Rather unfortunate if so, as aphantasia has been known about since Galton discovered it in 1880.
That's not really what the article is about: "Patients whose primary visual cortex was destroyed can still imagine, so the old idea of imagination as reversed seeing fails."
Knowing a thing exists is not the same as knowing how it interacts with other things.
It's been "known about" but mostly ignored in research until recently, and most people who know about their aphantasia probably learned about it in the last 10 years because it was extremely obscure.

There reason it is being talked about now is exactly that so many of us learnt about it from a study in 2015 and the subsequent interest.

Aphantasiac here, happy to discuss or answer any questions
What does you mother look like?
I have total aphantasia and this is how I usually answer: it's like having a picture of my mother in my head, only for it to be obfuscated by an opaque veil, and there's a system in my mind that can peak behind it and feed me informations. In the end: I can never visualise her, but I can "query" informations, and when I see her I match her immediately with what I know her to look like.
Does it apply to audio as well? If you think of a song you know well, do you feel like you "hear" the music in your head, as though playing back an audio file?

If you think of a movie scene you've seen, what is that like? Can you recount what was in it, even if you can't "picture" it? Or does this also prevent you from recalling the details of the scene?

People's ability to "hear" music ranges from nothing at all to being able to "play back" close to what they heard. For my part, I have aphantasia, I can't hear the sound I heard, but I can "play it back" in my own voice (which is distinctly less pleasing).

As for movie scenes, I rarely tend to remember specific scenes - I tend to remember concepts and dialogue - but when I do remember a scene, I can often describe it in detail, and I can sketch out scenes, be it from movies or real life, that I remember well with a lot of spatial detail.

I suspect I probably do remember less of visuals than people without aphantasia because I don't really get much value from it, but I definitely can.

Not the person you asked, but a fellow Aphantast: I cannot imagine visually at all. End-of-Yoga-class imaginary journeys are completely useless for me. I'm also faceblind. But I can imagine music I'm familiar with without any problem, and have a inner monologue (it blew my mind when I learned that some people do not). Also I have visual dreams, but nowhere near to the level of details that I have heard other people describe.

I image a movie scene: There is a man sitting at a table in a cantina. He has dark hair, slightly rugged clothes. Standing next to his table is a little green alien that targets a blaster at him. The person is sitting low, at an angle that prevents the alien from seeing that he has drawn his own blaster below the table. I know all of this, but I have no visual memory of it. If I had to draw what I see in my head it would be a blank piece of paper with arrows pointing at certain points, labeled with "Han", "Table" and "Greebo".

Some people have inner dialogues. Some authors are literally writing down what characters are saying in their head, and sometimes what they see them "do" as well.
Me here, inner dialogue frequently, inner monologue never (self-directed speech like "okay now I need to pick up the ...")

My inner dialogues almost always come with full fidelity, visual, audio, tactile, I can still smell the Marlboros on my dad's flannel even though he stopped smoking 20+ years ago.

Aphantasic here - I constantly have music playing in my head to the point of it being slightly annoying. If I really concentrate, I can separate out the parts like stem separation, but generally it's a fairly high fidelity recreation of the most prominent parts. There was a brilliant thread on Mastodon a couple of years ago where people (mostly musicians) were describing their inner-music abilities - mine turned out to be very ordinary. The only time mine ever approach what many of the others described is when I'm very slightly stoned - then my brain starts to compose original music at extremely high fidelity in basically any genre. I just wish I could get it out of there.
how is your proprioception? https://en.wikipedia.org/wiki/Proprioception

e.g. if you put your hand behind your back and move it up and down randomly, then stop suddenly, can you tell if it's stopped closer to your legs than your neck?

i cant think of a better test for it :( (clinicians?)

For my part (as someone with aphantasia) my proprioception is good, and to go further, my sense of space and my spatial reasoning is well above average.

I can also draw what I can't see pretty well from memory.

Can you complete tasks like answering the question "a square shaped piece of paper is folded once diagonally so two previously opposite corners are now on top of each other. Does the distance between the other two corners change during this fold?" I think most people would answer this by just imagining it, but I'd think the way I've described it is pretty hard to follow if you can't picture it. If you can answer the question, how do you do it?
I can't visualise things either and this is a task that my brain just solves for me analytically somehow. In this case I had to re-read it a few times and then knew the answer. I struggle with visual navigation but my brain compensates this with intuition (or whatever we want to call it) so I never really got lost but I'm unable to guide other people because that usually requires visual imagination (map, landmarks etc.)
(Also aphantasic)

I think about the axis on which the fold is performed. Because of “square” and “diagonal”, for the two corners to touch, the fold axis must lie on both of the “other two corners”. A reflection about an axis does not change points on the axis, both points are unchanged, so their distance is also unchanged.

Yes that's correct. How do you answer this one: a hollow cube lying with one face on the horizontal like a die on a table has a hollow pyramid inside with the same base horizontal on the bottom like a usual pyramid. Inside the pyramid is as large a sphere as will fit. A horizontal ray is cast from outside of the cube through the entire structure, passing through each surface it would hit. The location of the ray is not specified, only that it is horizontal.

1) State the order of the surfaces it hits/passes through if you choose to cast it at a point where it passes through the maximum number of surfaces in the structure.

2) Is it possible to choose a different point where it would still pass through the cube but would pass through a different number of surfaces? (such as by missing the pyramid or sphere or both). State the distinct counts of how many surfaces it could pass through depending on where you cast it horizontally, like how many different counts exist. (Being tangent does not count as passing through a surface.)

I would answer this question by just picturing it and moving the ray around in my mind. How do you do it?

This is a bit more stream of thought, hopefully that is helpful.

The pyramid can’t take up all the space inside the cube, only another cube could do that. So there must be some points that are “inside cube, outside pyramid” and other points “inside cube, inside pyramid”. The pyramid is given as wholly inside the cube so there are no “outside cube, inside pyramid” points. Same for sphere inside the pyramid. So it’s

    { out-cube | in-cube out-pyramid | in-cube in-pyramid out-sphere | in-cube in-pyramid in-sphere }
I struggle parsing the ray description, “horizontal” must meaningfully constrain the ray somehow (otherwise it wouldn’t have been mentioned), but I don’t know what that changes. Then I think about facts I know about rays - they can be uniquely specified with two points, or one point and one direction - oh, and we are given the direction is always “horizontal”, so we only need one point. The ray goes on forever so every “in” is “enter+exit”, so add 2 for every “in”. So it’s

    { out-cube (=0) | in-cube(2) out-pyramid (=2) | in-cube(2) in-pyramid(2) out-sphere (=4) | in-cube(2) in-pyramid(2) in-sphere(2) (=6 }
1) Maximum, that’s 6, from the last option, so “cube, pyramid, sphere…”, have to exit the innermost first, so “…sphere, pyramid, cube”. I don’t know where this ray is positioned, “halfway” might be a good guess, or maybe pyramid is half of square and circle is half of pyramid so “a quarter way up”.

2) Distinct, that’s `0 2 4 6`. `0` doesn’t count because we want “still passes through the cube”, so 3 counts exist. Thankful that “tangents don’t count” so I don’t have to think about them, because nothing immediately comes to mind on how to handle them.

yes this is correct. Thanks for writing that out, it's really interesting to read how you solved this without picturing it.

It's a bit surprising to me that it was unclear what I meant by horizontal/level, I thought this word is well-known and easy to understand. Here's what I mean by horizontal: For me, it means that with respect to the ground, the ray isn't rising or falling as it travels, i.e. it's level (like a plane flying in level flight with respect to the ground, not rising or falling). This constraint doesn't really matter I guess, except that I said that the cube is also level on the ground on one of its surfaces, so since you have to cast the ray in a horizontal/level way, you can't cast the ray at an angle through one of the corners so it goes through the opposite corner of the cube, since - if you think of the ray like a plane - you can only move the angle of the ray side to side not up and down, it stays in level flight = horizontal, so you can't cast it through both opposite corners if the cube is lying flat on the horizontal on one of its surfaces. As I just wrote this paragraph, I pictured what my description of casting through both corners the would look like and why it's not level with the ground anymore. I guess it's harder to follow my words without picturing it.

You mentioned it's not clear how being horizontal constrains the ray, based on what I wrote and what I meant about it being level, is it now clearer how this constrains some of the rays that can be cast? (Like how you can't cast a ray through the opposite ends of the cube now)? Or is that hard for you to follow? For me I think maybe my words could be written in a bit confusing way but I think someone can understand them if they can picture what I referred to. Without that mental picture it could be difficult though.

Your words are not unclear! You are doing a fantastic job of using words that work very easily with mental imagery, and but not at all without. I said I didn’t understand horizontal because without mental imagery I have no “floor” for the ray to be parallel to - I could have found something to be the referent for the horizontal if I had to, but once I thought I had explained why “horizontal” was mentioned I stopped trying to figure it out further.
That's really interesting, thanks for your answers!
It kind of becomes a set of math facts, and my brain does this spatial thing where I "feel" like I am doing the task with my hands even though, of course, I am not. I have a really good spatial sense. I can pretty reliably draw floorplans of places I have spent a couple days in, at least in spatial relation if not exact size. I'm very good at identifying potential furniture reconfiguration of rooms. With my wife it is an interesting dynamic - she has such a rich inner visual life that for something like thinking about a new piece of furniture, or a move of existing, she needs me to tape out the new layout. Her visual memory of the space blocks here from imagining the new possibility, or it is so deep that she need to reconfigure everything visually. I just am aware of the alternative
I’m pretty sure I have this. How did you find out?
When you look at something and close your eyes, do you also not "see it" immediately after?
1. Can't remember which way you came from just after a few mins of passing the same street. 2. Can't recollect your mother's face by closing your eye, but can recognize when you see. 3. Don't remember faces unless seen them for many times. 4. Can remember a favorite color. 5. Don't have a consistent handwriting.

Do these symptoms count?

When you close your eyes, can you make any visualization whatsoever? Not the press-fingers-into-eyes stuff nor from-memory visualization, but just anything. When I close mine, I can let my brain wander with little intention/feedback and my mind will create giant megastructures that I kinda sorta fly through. It's fully continuous almost like I'm zooming into a fractal.
99.99% of the time, it’s just black. Seeing things like you’re describing sounds like a super power.

The 0.01% of the time, I have seen blue lights. Without trying to look around too much, it’s something like this:

https://m.youtube.com/watch?v=-OzQ0zAtFL0

This has only happened a handful of times, maybe 5, definitely less than 10. I was in my mid-30s the first time it happened, at some house learning transcendental meditation. I opened my eyes for a second, thinking they were shining some lights to make it seem like something was happening. Sadly, I was never able to repeat this through meditation, but it has happened a few times as I try and fall asleep. I wish I could trigger it on demand. It’s super cool when it happens.

I'm fairly but not perfectly aphantaiac (I dream without images; I can see briefest flashes of people's faces if I've known them for years). The discussion is often flattened to "can't picture anything" but I also have some cool inner-mind tricks: namely, I have rich access to my inner senses of touch and hearing. To a lesser extent, I can imagine flavors well -- well enough that it helps me in the kitchen at the least. What about your other senses?
So you self-diagnosed yourself as unable to do something, based on what you imagine being able to do is like?
I posted a question but apparently it was shdow bnned automatically by HN. Here it is again if anyone cares: https://sharetext.io/j3wjsivi
yeah looks like it triggered a keyword filter to mark it as dead to me. Or a few people flagged it.

Either way it seemed relevant enough to me that I vouched for it.

Thanks for vouching, it seems to have helped.
I still think this is fundamentally about how difficult it is to describe qualia.
Aphantasia is a real thing. As are probably many other differences in how our brains work. But the difficulty of describing qualia is likely why we are so unaware of them. And why even the "known" ones remained largely obscure until the age of social media
Aphantasiacs seem to be able to describe visual qualia as adequately as anyone else when the visual stimuli are currently present. But we do see descriptions differ between aphantasia and baseline in two cases: when the visual stimuli is recalled from memory, and when the visual stimuli is imagined. If it was about the difficulty of describing qualia, I don’t think we would see a difference between “visual stimuli present” and “visual stimuli recalled or imagined”.
Yeah I agree - how would you ever know if this is real or if it's just some people saying "sure of course I can visually imagine things, just like dreams" and other people saying "omg I can't visually imagine things at all, it's just like dreams".

I guess you can maybe do better than nothing but it doesn't sound like they have got very far. Also...

> Why This Matters

Come on guys at least try.

In my experience the people who most doubt aphantasia tends to be people who clearly have aphantasia.

I have aphantasia, but I have also during meditation had one experience where I could clearly see an imagined scene vividly, and the experience was nothing like when I "imagine" things and can't see them.

I know I wasn't sleeping because I was aware of the sounds in the room I was in for the duration.

But I also see images when I dream, but that one experience was far more vivid than any dream I've had.

Aphantasia is fake. I can “see” when dreaming, ergo the brain simply (adaptively) suppressing the same only when awake.
The most important thing to remember when discussing this stuff is that how you experience reality can be drastically different from other humans.

I’ve worked as a professional photographer for twenty years and I visualize absolutely zero with my eyes closed. It’s only recently that I learned of aphantasia. Even on most psychedelic journeys I don’t have closed eye visuals, NN-DMT being the consistent exception. Everything is more of just a “knowingness”.
What’s it like to dream while you’re sleeping? Do you ever “see” anything then?
I can't visualize at all when awake, but I have been into lucid dreaming in my past and my dreams were visual and more detailed than real life (no bad lenses for the light to go through, I guess). I can also visualize a little bit when on either edge of sleep. I've been noticing that the occasional images that I see in that state are becoming more colorful and detailed. I'm hoping that means actual phantasia in my future, but that's probably just wishful thinking.

I should add that the only things I've ever been able to see when fully awake that didn't come through my retinas are auras (I went through a "learn to read auras" phase a long time ago) and ghosts. Or at least things that I'm assuming aren't actually real, like images of a friend who died before I knew about it and a woman who watched me watch TV for a few weeks. So this might mean that I'm not a complete aphant, or it might mean (based on this article) that sometimes those brain regions/processes can still align for me occasionally.

I do see images when I dream. It can get pretty immersive. Brains are wild.
I've had dreams where I was "there" and it felt like being present in a scene in a very real way (for a dream). But ask me to close my eyes and visualize a blue table with a red apple on it and its nothing but phosphenes at best.
Have you worked mostly as documentary photographer, or did you also do stages setups, like portraying people? I am only a photo enthusiast without any mental images and I struggle with portraits. Since I know about aphantasia I am wondering whether it has something to do with the absence of mental images.
Honestly, I’ve done it all. I’ve shot thousands of headshots and portraits and hundreds of events. I’ve not typically been a “conceptual” photographer such as somebody like Art Kane. I started on film and moved to digital in 2003 before I was shooting professionally. I get more of an “idea” in my head, however I don’t “see” a final result. Digital has helped immeasurably to refine my work more quickly. Just as I “know” what a red fire hydrant looks like but I do not “see” an image.
As somebody who only has closed eye visuals in deep meditation or in dreams, I would maybe describe what you call "knowingness" as "abstract representation"?

As a kid I've always been really good at these "imagine how this shape folds in 3d" kind of tasks, and I would generally say I am above average at imagining how things relate to each other in 3d. I just can't turn it into an image in my mind's eye

Yes this. I have, based on a battery of spatial reasoning tests I took years ago, way above average spatial reasoning capabilities. I also notice a lot IRL that others do not, based on anecdotal evidence.
I have aphantasia as well, but have had visuals once during meditation, much clearer than in dreams. I've never managed to repeat it. Does it happen regularly for you? Any tips?

Like you my spatial reasoning is very good, but no image.

This makes no sense if you can visualize things when you’re dreaming your brain has no problem visualizing things it’s just correctly suppressed when you are awake
It's not suppressed for the vast majority of people. If you consider that "correct", odds are you too have aphantasia.
This is always a hot topic on HN.

My takeaway from all of the discussions is that the ability to 'see' an imagined visual representation of something exists on a spectrum from absolutely nothing ever, into a minds eye abstract idea of an image (like a melody heard in your mind rather than your ears) toward a full ability to see an image overlay in the visual space. There's a lot of debate as to whether this is a trainable ability.

I've just spent the past 20 minutes thinking about how I do it, I can do both eyes closed and eyes open, at work, I mostly talk with my eyes closed actually because my thinking style is generally quite visual. I then spent 15 minutes trying to figure out how to explain it, and it sounds a bit nuts...for eyes open there are generally 2 things involved for me, one is what I could describe as "disassociating from my eyes" my eyes are open but somehow my brain just kinda suppresses the image into what becomes an out of focus low contrast blur, and then my eyes typically look up a bit. The images themselves appear in an area that feels like it's in the top of my head where a darker area has formed, in that space I can think about what I want to visualize, or my brain serves me images if I'm thinking. I googled around a bit, according to this research folks who have strong minds eye report a few different places that they use to build the image within, some people report they built it out in front of them, other like me build it "inside", other folks report other spots: https://www.biorxiv.org/content/10.1101/2025.09.30.679629v2.... - this one is also pretty interesting: https://www.sciencedirect.com/science/article/pii/S105381002...
Appreciate it. I don't really miss it much (though it explains various things about my preferences, such as finding visual descriptions in books extremely boring unless the language used itself interests me), but that one experience did drive home that I am missing something, and so occasionally I do try to experiment to see if there's any way I can trigger that experience again.
I've also had this kind of topological knowingness which I couldn't name. Another comment here says "schematic conceptual" which captures what it feels like for me.

Another good explanation here is that it's all taking place but that last step of creating the visual is suppressed (as intended) while conscious as that would be hallucinating.

I feel that I could visualize internally but there's a curtain pulled over the visualization part of it. It's there, i feel it but it's blocked from my sight somehow. I've built intuitive ways to probe the imagination so I technically experience my image-less visualization. However, when I attempt to visualize something more complex (there are a lot of elements or minutiae) I'm reaching my intuitive limits. When it comes to auditory imagination, I can literally listen to a song from my own head all day long with no effort.
I sometimes called it "textual memory of an image", but I also liked TFA with "we experience these as an awareness of a set of spatial facts"
I always assumed that when people say "imagine this image..." that it was about the contextual nature of it. Only several months ago did I learn that aphantasia is a thing and I'm among the ~4% of the population in this group.

With psychedelic journeys I do get visuals but they are indescribable. My pet phrase for it is "swimming with God" (disclaimer: I'm an ardent atheist).

(comment deleted)
Exactly the same here. When I learned that other people actually could visualise things, it made me realise why I've spent my life being a commercial photographer and camera developer. Capture the images - I guess most people get this for free to some extent
I am confused. You can't recollect a friends face? You can't imagine the feeling of sandpaper? You cant bop to a melody in your head?

The "mind's eye" isn't an actual image. It doesn't pop into view like augmented or virtual reality. It is imaginary.

How do you know that? Honest question.
>I don’t have closed eye visuals

Nobody does, this is all unfalsifiable nonsense, it's an artifact of the language used to describe imagination.

This kind of matches my experience. Not sure if I have Aphantasia, but my mental visual imagery is pretty sparse and not that well formed.

And yet, I can somehow imagine the look of a specific person or thing. I can't really see it as a vivid image, like actually seeing something in real life, but I have a sense of imagining it as visually distinct from any other image.

My audio imagination is top-notch though, I can replay songs and sounds in my head perfectly and vividly.

[delayed]
> Engineering types most commonly are strong in conceptual thinking. You can imagine complex systems and how they connect but it’s hard to describe and linearize this into words. You have to translate. Again it’s sort of an imagined picture but not really.

I guess I have that ability, in that I can relatively easily figure out spatial relations or can map out code mentally. The photorealism I am a 0 on.

Is linear thinking just a stream of conciousness thing where you basically list attributes? If so then I guess I have that too.

But id still describe myself as an aphant.

According to Ed Catmull surveying Pixar staff, there doesn't seem to be much more than a minor correlation between ability to visualise and artistic ability.
I can personally watch a movie in my head, eyes open and I’m super not artistic but very engineer oriented. To the point that I realized I should be dropping software for mech eng
Anyone who doesn't believe this is real needs to explain the well-documented cases of acquired aphantasia. Good luck with that.
The article is only about the absence of mental images, but the same is true for all other senses as well. People might be able to recall or imagine images, sounds, smells, tastes, feels while being awake or not. And it can be in all permutations, tho, vision affected seems to be quite common.
I've got a moderate form of Aphantasia, where there are images in my head, but I'm unable to fix them in place and extract information from them. So I might think you have green eyes, but if you tell me they are brown, I wouldn't be able to refute you from my own memory.

Practically, it means I'm rubbish at remembering people. I've developed some techniques that help, but if someone changes their look significantly, it's very hard for me to identify that it's the same person.

I'm still learning how this has impacted by life, and strategies for working with it. As a simple example, my wife's family was really into cars, so when I got to know them I learned all about cars. When I met my wife, I couldn't identify a single vehicle on the road, except maybe a Hummer, but after 2 years, I could quickly pick out the make and model of 95% of traffic.

Looking back, I can see this is because rather than remember what different cars looked like, I created a taxonomy of ALL cars in my head, and became able to sort any vehicle I saw to fit there somewhere. So when I identified something, I wasn't matching it against previously seen things, but rather eliminating all the things it couldn't be to arrive at the remaining possibility.

A couple weeks ago, Neil deGrasse Tyson had neuroscientist David Eagleman as his guest on Star Talk. David discussed his friend and co-founder of Pixar, Ed Catmull, has aphantasia and that Catmull tested the directors and animators at Pixar, discovering that many of its top artists are also aphantasic! [0]

They have a theory that artists who have to struggle more during the training and developing of being able to express on medium develop into better artists.

I thought that I'll never be able to tell what non-aphantasia people see and how they perceive things. I see full blackness with some noise, but I can't visualize a thing.

This was until I tried some magic mushrooms (psilocybin as main ingredient) and I was shocked that with my eyes closed I was able to actually see things, mental imagery, objects, etc. After the effects wore off, the blackness has returned I couldn't see anything anymore. To me this is proof that aphantasia is real as I was able to compare it to a different state of mind where visualization is possible.

It's quite unfortunate that research on psychedelics is limited due to the insane war on drugs.

Same but in reverse, a certain psychiatric medication turned on an internal monologue I've never had before and it drove me absolutely, literally insane until it wore off. Never again. The most inane, moronic commentary about my day to day life as it happened, like Barney speaking through me. I normally experience the world wordlessly, mostly visually, and construct ideas and actions that way (thinking about, say, getting a glass of water, I'll picture the process), so having internal speech suddenly thrust upon me was awful.
I haven't tried mushrooms, but had some medical trouble and with very high fever + medications there was times of rathr vivid visualisation while awake which I never experience otherwise - full blackness as well.

Wouldn't recommend getting sepsis just for that though.. mushrooms seem safer

Also an Aphantasiac, the quote

> “we experience these as an awareness of a set of spatial facts.”

really resonates with me, as to how it feels inside my brain. I'm also really good at shape rotation and spatial reasoning despite not being able to literally picture the environment.

my pet theory is that there are just different places in the stream of consciousness your attention can rest and mine cannot be pointed at the 'mental machinery' that actually produces the images but instead rests at a higher level of abstraction after the visual signal is integrated into the representation of the 3d world that gets used for tasks like shape rotation.

I also don't have an internal monologue most of the time, but I can consciously will myself to do it, and then it is hard to get out of that mode, analogous to the 'you are now breathing manually' meme. I can do it but it feels annoying and slows down my reading and thinking.

Now that we have agentic systems the analogy of the internal monologue being a subagent is probably a good way to describe it, yeah i could read the thinking trace word for word, but most of the time it feels like existing at the level where the data that gets extracted from the stream of thought gets integrated.

Honesty it's so interesting to me how many different ways of experiencing the use of your brain we exist. Sort of reminds me of how there is no single method of crawling a baby learns, there are a bunch of different ways to do it and children just discover one and go with it. Walking seems to be different in that there basically is one good way to do it. I guess there are a lot of degrees of freedom in how the process of being can run on the brain.

It has been a lot of fun talking to those who are Aphantasiac. I am the complete opposite to the point where I think almost exclusively in imagery and when talking to folks I translate visuals to words on the fly. For a long time when people said that they saw black when they closed their eyes I assumed that meant that they choose to "see black".

So whenever I chat with someone with is Aphantasiac being able to compare and contrast has been a treasure trove. Hobbies, careers, romance/relationships, what we like to read/watch, what we are good and bad at. Having our two extremes allow us to do rapid research see what is opposite and what isn't.

And then in the same way I will describe smells by how they look like they will describe stuff to me that I struggle grasping without visualizing it and that is a joy.

High five brother, I find these threads fascinating, because even within the group of people who have hyperphantasia like this, our experiences differ wildly.

"Describe smells by how they look" - that's synesthesia maybe! A bridge too far for me - I'm more likely to describe what the situation I was in when I smelled a given scent most memorably, rather than how the scent looks.

I also explain things verbally by referencing an internal picture and describing it, and find tacit knowledge very difficult to express in that vein.

I'm pretty sure I have this, for all senses, and I only just learned there's things other than iñner eye (which I only learned of a few months).

If people have an "inner taste" or "inner hearing", why bother eating a sweet or playing music?

> Asked what sits beside the television, they answer without hesitation, but “we experience these as an awareness of a set of spatial facts.”

This helps me understand what little I do seem to have.

Maybe the most vivid thing that I can imagine is the world map, but... I wouldn't call it visual. But I can recall that Europe is east of US, and Italy looks like a boot.

Perhaps it is just spatial facts.

> If people have an "inner taste" or "inner hearing", why bother eating a sweet or playing music?

Because the interior version is strictly inferior to the real thing, at least for me. It's, maybe, 80% as good, but that last 20% is a real humdinger.

Especially for music, I have a hard time hearing it in my head and not playing/singing/drumming along with it. Currently working on "Winds of Change" by the Scorpions as practice, and it's basically been playing in my head for the last 72 hours.

I do have to listen to it occasionally to refresh, but it certainly makes learning music easier... if not infuriating. Looking at you Lou Bega, and Rob Thomas.

80% is still pretty high!

Does 80% mean "tastes like a dull chocolate bar, but still basically a chocolate bar", or more like "like a nice chocolate bar but somehow 20% less enjoyable in some looser way"?

Perhaps this is why I can't identify the beat in the music.

Like a nice chocolate bar, but echoed - so I can remember what it tastes like enough to want one, but not satisfy the urge to actually have one. Ephemeral, rather than satisfying.
How do you decide what you're in the mood to eat?

For me, I sort of imagine the sensation of eating something and observe how I react to it. If it's a strong positive reaction, that's what I'm in the mood for. Otherwise, if it's kind of a more bored reaction, I cast my mind out for another idea and try again.

A test was recently mentioned to me, regarding aphantasia vs visual thinkers.

Imagine a cube that has a red top and bottom and front face, and all other faces are blue. How many edges are red on one side and blue on the other?

Now, in solving that, if you are a visual thinker, you may have actually mentally "turned" the cube to "look" at the other side. I can exactly pinpoint doing that in my mind, to count the edges I couldn't "see" from the front.

> you may have actually mentally "turned" the cube to "look" at the other sid

As a visual thinker, I could have rotated the cube if I wanted, but I actually looked at all sides at once, if it makes sense. I could "see" all sides of the cube at the same time. I am not sure how common this is, but in addition to seeing it as an "image" I can sometimes, not always, also sense the total structure of a construct and be aware of all of the physical "sides"

I never find the ability to visualize things, or imagine voices or sound, too interesting, as I have never used those abilities to do anything practical. I do not rehearse words in my head before talking, or create an image in my head before drawing art.

Doing art teaches you that you only have a general sense of what a lot of objects look like. People need reference for almost everything they haven't drawn before, and can struggle to understand the proportions of things they're directly looking at.

I built a house recently, I'm not sure how much fun that would've been if I couldn't visualize things before building certain features, yes I built it off plans but they're not 3d so being able to draw a 3d image in my head is extremely helpful.
It's funny, when I heard the idea that some people can't visualize things I was unbelievably jealous. Until my mid-30s I had extreme hemophobia and if I just glanced at a cut, a surgery scar, or even walked into a hospital my mind would fill with visual memories or imagined images of wounds, blood, and who knows what else. Then I'd pass out. Even looking at an ultrasound would make me very woozy.
You are hopefully aware though that this is not the norm. Many (if not all) artists tend to visualise their work before and while they are doing it.
Watch people draw, and you'll realize that can't be true, or at least is a very incomplete description of what's going on.

People have processes they go through to eventually get to something reasonably correct. Systems for drawing people, perspective rules, etc. These get extremely elaborate. They shouldn't need any of it if they could fully visualize the scene. They'd just need to copy that image to paper.

You'll hear people say things like "trust the process". They are struggling with what they're drawing looking wrong to them, until they're fairly far along and the shapes are fairly complete. Even when they're doing things correctly, their brain isn't recognizing it.

> They are struggling with what they're drawing looking wrong to them, until they're fairly far along and the shapes are fairly complete.

In general I agree, but not always. I have a friend that has always been very good at drawing, and when he starts drawing it's immediately obvious that he has a precise idea of what he's are going to draw. People often gather around him when he draws, because it is entertaining it look at him, it feels like uncovering a frame cover with dust or something.

I assume it is not uncommon among professional drawers.

Yep, I often find the hardest thing is coordinating the hands to produce what the brain is showing. My frustration often stems from the meat gloves just not being fast or accurate enough to keep up.

(Designer/illustrator/animator, now software engineering.)

When away from my instruments - guitar and piano - visualizing playing whatever pieces I'm working on is enormously valuable in that when I return to the instrument my retention is significantly improved compared to when I don't visualize my playing. I'm pretty sure this has been tested in RCTs, but I don't have them readily available.
I, for one, find it very practical.

I do a lot of thinking by visualizing relationships between concepts in a kind of graph. When I draw, I visualize the scene first. When I build widgets in my wood shop, I visualize the result and all intermediate states. When I was writing 3d renderers (a long time ago), it was immensely helpful to visualize the points and triangles in my head.

People with no imagination are rewriting my industry as well
Haha, but the subject is not people with no imagination. It’s people whose imaginations aren’t visual.
I see
We don't... at least not in our minds anyway.
Insensitive comment for this thread, but I suspect on purpose ;-)
I think it's quite the opposite, they live in an imaginary world with no consequences.
I'm aphantasic. I dream normally, seeing all sorts of imagery. I have accidentally had a couple lucid dreams in my lifetime, which got me interested in the methods to trigger them intentionally, all of which have failed.

The Wake Back to Bed (WBTB) method has been especially frustrating, because I'll see my usual nothing when my eyes are closed, but then for the very briefest instant I see a dream image that immediately disappears the moment I notice it.

I wonder whether whatever makes my brain aphantasic is also responsible for switching off those almost-lucid images.

I have no clue if I'm aphantasic (I genuinely have trouble feeling like anyone describes anything resembling my experience in conversations like this), but I had many years of lucid dreaming from being prescribed medication for my insomnia as a kid. It started out being pretty much every night, and then slowly became less frequent until nowadays it's maybe once every month or so.
"Wake back to bed" works for me. I don't do it intentionally, I often wake up between 3 and 5, use the bathroom, go back to bed. It only triggers a lucid dream maybe 5% of the time but I've never had one without that.
I am in the quarter of aphantasics that report no imagined sensations of any kind, no inner sound, smell, taste or touch. I do have some very basic imagery occasionally while dreaming, a bit like Dali’s drawings. Never faces. I am also remarkably bad in remembering faces (or names) but recognise them just fine when recent. I don’t think in words, shapes, or relations. I think in words that are on the tip of my tongue and make sentences in their “rhyming”.
I'm also aphantasic and dream normally. The only time I've been "awake" and been able to visualize anything was the few times when I briefly woke up in the middle of the night and when I closed my eyes I was able to see a room in vivid detail but everything was in grayscale. This has happened multiple times and is probably more connected to being in sort of a "between-state" of waking and sleeping than the ability to actually visualize with my imagination.
I'm also aphantasic and dream normally.

I have some intermittent ability to lucid dream. I have noticed that if I am acting as a "passenger", the imagery is vivid and I will be able to recall everything. Sometimes something in the dream will prompt me to think. It might be entering a phone number, or reading text. As soon as I engage the process of thinking, the imagery goes away. Long lucid dreams for me rely on me being able to remain in the passenger seat.

In my waking life I consider my aphantasia similarly - I can imagine things and get the briefest of a "snapshot" of an image, but any attempt to hold onto it means it vanishes - I don't know how that's related but I suspect that it is.

I know this is different to how I am wired for sound, because I have inner music, inner voices, etc. I can replay music at will, change voices, investigate and modify them, all with perfect quality of audio recall. Earworms can be really annoying ;)

FWIW I’m exactly like you. My ability to replay music sometimes surprises me.

Sometimes I’ll hear a song on the radio I haven’t heard in decades and be able to anticipate tiny details precisely (like, “here’s where the harmonica comes in in Karma Chameleon” or “here’s where the fretless bass is gonna bend a note”. You?

I'm also aphantasic and dream normally, and I once got really into lucid dreaming for a ~semester in college.

My best successes would occur after drinking a cup of coffee and immediately taking a nap before a study session.

It was great, I "learned how to fly" and could "morph" my dream into whichever direction I wanted.

One thing stuck out though: whenever I would try and focus on something, I would see a black dot enter the center of my vision. The more I tried to focus, the larger it got. If I focused on an area attentively enough, such that the black circle became all encompassing, I would wake up.

After a few times of this, I could start to notice the focus, and then sort of relax out of it, and thus continue the dream.

It feels like the black dot is my real-life vision coming into focus, and "winning" over the visual aspects of the dream. It's always continuous from black dot to eyes opening.

I rarely lucid dream now, but I've noticed a similar thing happen whenever I try to read text - the black dot appears and I wake up.

Wish I still had unlimited time to go back to sleep!

I'm not aphantasic, but that's exactly the experience I get when coming out of a lucid dream. Except it's my expected surroundings not black. Gets a bit weird and inceptiony when it's the wrong surroundings! Given the number of cultural references along these lines, I suspect it's not uncommon.
Focus takes training, just like physical exercise, it is a super power to be harnessed.

You can train yourself up by looking at your hand, then building a body, then building a room, and maintaining all of it. When you are strong enough, you walk outside.

My lucid dreaming has always been when I'm in danger, like this description of a Sadako dream

https://medium.com/luminasticity/beating-up-sadako-82c5fb3f0...

So I've never been able to trigger a Lucid dream in any particular method but often when I am being attacked it's like the adrenaline makes me think wait a second this is a dream. Some times if I get scared enough and wake up from a dream I can then make myself go back to that dream to confront the thing that scared me (but knowing it's a dream so I have the upper hand)

shikantaza (zen meditation, basically) has significantly improved my ability to visualize.
Interesting to me that three different people have responded with the same "I'm also aphantasic and dream normally" start to their message.
When you express you have aphantasia to someone, one of the most common questions is whether you can dream. As someone with it: Yes I can dream. They're so real they are lifelike. And not just visually. In my dreams, reality and history itself can be different and to me, history didn't change. It just is.

I rememeber in one dream I was some sort of captain and I saw one of my closest friends. We'd been crewmates for the past 40 years and I remember all my memories with him and why I trusted him with my life. I was 22 when I had the dream.

That's fascinating. Do you gain access to facts or knowledge that are verifiable afterwards? Have you ever become fluent in a foreign language for a dream?
In my experience, it feels real but the feelings doesn't really hold up to scrutiny. It's more like the set of a play than a real world, where a thin facade evokes all the right cues in the audience but couldn't actually be used to trick someone into thinking it's real.
I don't have aphantasia but I sometimes also have dreams that are so realistic that when I wake up I feel as if it was some type of alternative reality. In some cases it is also as if I am watching a "movie" where the life I am experiencing is not my own, but I will still know each person.
It is a good question because aphantasics that can dream normally are far less likely to engage in the sort of "aphantasia is just semantics" denalism that is largely disproven given modern science and online discourse. I.e. it is a very strong credibility signal that what follows is not just cope / self-delusion, but actually potentially useful and interesting self-report.
Doesn’t help with the NPC allegations
I am also aphantastic, and I don't even get to dream properly. I had a dream perhaps no more than 10 times throughout my life, and almost always due to some unusual circumstances (very rough hangover, grief, broken heart). Even experiences with rather high doses of psilocybin or LSD were profoundly non-visual for me, and I made several attempts to get there.
How’s your sleep quality? I (aphantasic) only ever dream on weekends when I sleep in over 8 hours (rare), and having to get up to pee after 4 hours also cuts in.
Depends on the coffee intake and stress; when I am on vacation, I sleep 7-8 hours without waking up. I am lucky that I don't need to pee during the night, though.
Question for visualizers: is imagery held steady in your dream, or does it constantly shift and morph?

I’m aphantasic and like I’ve seen many people report here, I can kinda almost conjure up images but can’t hold them steady even for a microsecond. It immediately disintegrates and can’t be brought back.

In my dreams the imagery always shifts, but not in the same way. It’s held enough to be recognizable before changing into some other random nonsense like happens in dreams.

(I dreamt last night a StarCraft 2 YouTuber I follow was spamming raven auto-turrets over some people from a helicopter, which they shot down with a machine gun, and the youtuber survived the crash but he didn’t look at all like himself and that confused me, but we were in an Italian castle, and I was hiding from gangsters, but my boss had traveled to Italy and we were in a hospital where he was getting “torso reduction” and I put my hand on the small of his back, and it was my wife)

Certain types of meditation training involve specifically this faculty - the ability to hold a particular image steady in the visual imagination. Having the ability to vividly imagine a visual scene or a simple geometric shape is very much a muscle which can be trained; the brain is very plastic in this regard.
My experience is similar.

I have dreamed visually, sometimes vividly, but not so common these days that I awake remembering a dream. Lucid dreams rarely - and almost exclusively as a flying dream, like at some point I just realise I can fly and then I'm in control for a while until I wake up. Fun when it happens but I have no idea or technique for making it happen.

When falling asleep I can have random visuals but I can't control them, and trying to do so tends to kill them off.

Yeah it does feel somewhat like the rational and external sensory processing parts of my brain are maybe suppressing the inner-generated imagery.

I feel like when asked to 'imagine an apple', some part of my brain is sort of visualising an apple, I just can't "see" it. In other threads about aphantasia, normies have wondered how we enjoy reading. But I have always loved reading fiction and, like with the apple, I get absorbed in the book and am imagining it in some sense, just not 'seeing' it.

People with aphantasia probably overestimate how good it is.

I have quite good visualisation ability (based on spacial reasoning tests and ability to visualise complex software systems in detail) but it's not like seeing something in real life; there is much less detail. Though on the plus side, I can manipulate the scene flexibly; I can zoom in, rotate, hover but a lot of detail is missing.

It's not blurry, it's more like what happens when you watch an AI-generated video of a four-legged animal walking and you didn't immediately notice that there was a fifth leg which popped out briefly before disappearing again... Or a bunch of mice are running around and one of the mice splits into two. It has a similar kind of quality where it's not constrained by the laws of physics and I only really see what I choose to focus on. What I'm not focusing on essentially disappears; for example, the animal I'm visualizing could have a fifth leg but I wouldn't notice as I'm not focusing on that. I can zoom into some detail and it becomes clearer/more realistic but I sacrifice the big picture view. It's not uniformly vidid like something I see but every part of the image exists on a spectrum of how real it looks.

Though I think the emotions are the similar to what I actually experienced (if it's a memory) so it feels like re-living the moment.

“Science” this is not. It seems closer to religion. “Rewriting” imagination is an amusing oxymoron.

This distinction consists of sharing visions and describing your interior life that is ultimately intangible, beyond words, and unknowable to other human beings. There are no diagnostic criteria or indications, but drugs sometimes play a part.

Commenters in this thread are making claims about these but even further, judging and speculating on the interior lives and abilities of other people, hypothetical people, people you haven’t met. These seem problematic.

Aphantastic people of HN. Do you struggle remembering things in detail? My gfs family is all aohantastic and they just realized that it’s why they tell stories that are all a bit inaccurate. They remember the story but when placement, colors, shapes, etc come up, they can’t really tell you what it was. Comes up in weird ways
Yes. It’s called Severely Deficient Autobiographical Memory (SDAM).

I suffer from it quite badly. I can remember broad and important details, but struggle to remember even moderate details from anything beyond the past 2-3 months, with sharp falloff after that.

Once I started using Immich and was able to see my old photos from across adulthood and childhood (I used to just dump them onto HDDs), I experienced a sharp reconnection with myself and my past.

Maybe they could find something similar (Apple Photos, Google Photos, Immich, etc.)!

My internal thoughts are verbal and don't see pictures as a normal part of my inner though process.

When someone says "imagine a pink elephant in the room" I don't see a pink elephant, but instead have an inner dialogue to the effect of "ok, so there's a pink elephant in the corner." I may also recall an image of an elephant, but it's not pink and it's not really in the room.

When there is a concrete thing that I have a memory of ("picture a squirrel", specific things from holidays, etc.) I can see flashes of still images from those. I don't see a generic squirrel, but a specific image/memory of a squirrel I have seen.

I have general placement/shape awareness but not so much colours or other specific details. I can infer things like colour from context, or have a thought to the effect of "that building was white" but I don't really see the building as white.

Yup, I consider it just bad (narrative) memory compounded by aphantasia. Can watch a film or read a book and barely remember what was there the next day. Same for life events, with exception of very strong emotional triggers, or very well-connected systems - ie could describe better some system I was building 15 years ago than what last christmas was like (i assume it happened, there are pictures).

For me, recall is bad, but recognition is OK - things 'come back' easily with hints or photos. But I guess that's how memory tends to work, and motivation to plenty of pictures/videos.

There is the theory of too many people being born, with not enough souls to populate all those bodies.

In that theory, people without an inner monologue and without imagination are soulless, real life NPC.

To me, this inner world is an essential property of being human.

That theory sounds rather esoteric and arbitrary - defensible in some circles I'm certain. Lack of visual imagination or inner monologue does not in any way imply lack of 'inner world', nevermind the lack of essence of being human, whatever that is.
Let’s do a quick survey for aphantasics:

1. How’s your audio-lization? Can you hear music (accurately) in your head? Can you pick out instruments, pause, rewind, etc?

2. Can you visualize pure motion? Maybe you can’t visualize a woman clearly, but can you visualize the motion of a woman doing, e.g., jumping jacks? (For me, I can see complex motion clearly without seeing any underlying shape, if that makes sense)

3. Can you visualize just colors? I discovered that I can conjure up colors without any associated shape. Takes a bit of patience but the color eventually arrives. Quite a thrill for an aphantasic!

1. It's kind of like humming or singing, just internally.

2. Only via memory recall and even then its not stable and I don't "see it" with what my eyes are seeing/processing but more with the memory/recollection part of the brain. As such I can't visualize a unique image of that, but can construct one internally, often recalling different memories/images of the various parts of what I'm constructing.

3. No. I can't visualize (or really "see") colours on their own. When visualizing a colour I recall things that are that colour from memory (an apple, grass from a particular place, the Windows XP background, etc.). It's not that I don't know/remember that something is a specific colour, just that that part is not recalled/imagined visually. Or when I do recall colours of objects/pictures I can't hold onto that image.
