       | 
       | I can't draw well but I can draw anything. I know the concepts
       | and can poorly draw the approximate.

         | So I might imagine an Apple as a circle but if I need it in

         | and able to see the red, the stem, peel it with a small knife,
         | add a chunk taken out because it was bitten, etc.

       | The article kind of comes off as spammy/scammy and I fully

       | 
       | I have a propensity for staring at points in space and
       | daydreaming/visualizing to the point where it thoroughly annoys
       | my wife. Right now I am rotating a small grey elephant wearing
       | blue boots and a red blanket with gold edging on the blanket in
       | my mind's eye whilst staring at the HN web page and there is not
       | a single thing anyone can do to stop me from doing it. It's also
       | free which no doubt irks a number of CEOs and founders who have
       | yet to figure out how to monetize it.
       | 
       | I have a family member who describes themselves as "visual
       | primary" but during conversations of what this means woefully
       | admits that they need to "see things" to know what they look
       | like, cannot visualize rotating an elephant nor picture what the
       | underside of a soup bowl might look like if they had never looked
       | under that particular soup bowl but had looked under many other
       | soup bowls throughout their life. I liken the ability to
       | visualize as my first encounter with NeRF "Yes, it's like that!
       | Seeing things from other angles even though you'd never seen that
       | particular angle."
       | 
       | The human mind, it is quirky to say the least. Quirky in that I
       | can now rest easy because the amount of HN karma I have
       | accumulated has taken on a pleasant shade rather than the jarring
       | visual noise it previously was when it was below 2000.

       | 
       | Once when I was in elementary school falling asleep on a desk
       | during study hall (just closing my eyes and pushing into my arm)
       | and concentrating on the cool color blast thing that results.
       | 
       | Then like a year ago with my head on a pillow in an odd
       | configuration. Both times I thought I had an insane dream that
       | was so vivid I ended up telling people about it and they were
       | confused and thought I was crazy.
       | 
       | I've never been able to repro it and eventually I just gave up
       | and forgot, thinking it was some blip. Gonna try this out again.
       | I've never been able to "see" things in my mind for as long as I
       | can remember. Even dreams are mostly felt, not seen.

       | showed me it didn't exist. Everyone who claims to have it just
       | has WEAK visualization and trying harder to visualize will give
       | you the same results. It'll take a while, think of it as a
       | muscle. Use it or lose it.

       | So, wait, are people normally actually seeing images, with their
       | eyes, when they imagine what something looks like? Like, the
       | brown-blackness of the back of your eyelids gets replaced with
       | something you actually see, like it's projected there?
       | 
       | I can imagine what something looks like, and I guess I sort of
       | 'see' it, but closing my eyes doesn't make it any more real. It
       | doesn't seem to involve the eyes or any part of the visual system
       | at all - it's somewhere else in my head.

         | 
         | Most people are like this, with variation in the degree of
         | vividness and control. Some people can make realistic detailed
         | scenes, for other people it's harder and their images are often
         | blotchy or lacking in detail and colour. I'm in the latter
         | group.
         | 
         | If you don't have any of this at all and you're surprised by
         | the whole idea, you are probably aphantasic.

         | If I remember correctly, aphantasia is inability to visualise
         | images, objects or memories in the mind, and this seems to be
         | what the author actually refers to. The alternative, to
         | actually perceive imagery with the eye that isn't there is
         | usually called hallucination. The article doesn't get at this
         | difference and seems to be based on Youtube videos about
         | aphantasia.
         | 
         | If you've ever had a dream with vivid first person eyesight
         | (like most people during dreams) then it's easy to see that we
         | should be very capable of producing high quality visuals
         | without external stimuli.
         | 
         | I've been practicing on this kind of thing as it's a technique
         | for dropping into a lucid dream. In my case, I manage to find
         | some kind of repeat pattern in the visual random noise of my
         | closed eyes. Slowly and consciously I manage to see clouds or
         | waves on an open sea, maybe add color. Then I can try something
         | more advanced. If going to sleep, these images get more vivid
         | and might classify for something called hypnagogic
         | hallucinations[0], but then it's not quite the same level of
         | conscious involvement steering what to see. In any case, it's
         | nowhere near what I'd imagine as useful for an on-site photo
         | session, more like a high effort meditation.

           | Try your meditation routine while sitting in a warm shower
           | with a visual focus. That for me gives me the same intensity
           | as the true hypnagogic level visualizations while still
           | having close to full mental faculties.
           | 
           | Some people report being able to use audio patterns as an

           | describe for rotating a die, and I can place that abstract
           | visualization in the 3D space I see before my (open) eyes.
           | 
           | I think it's more likely that others describe this abstract
           | visualization as "seeing" although they don't really see it,
           | as opposed to them really seeing it as if it were real. As
           | you say, it's difficult to describe. It's like a memory of
           | having seen something, and people might describe that as
           | really seeing (because it's like a memory of really seeing),
           | but in fact it's not.
           | 
           | It's like hearing a song or other piece of music in your head

           | (for instance multiplication tables).
           | 
           | Once I was on an exam and I could not understand my own

           | was happy that my memory image was accurate although
           | frustrated for not managing the space in the page properly.
           |

           | 
           | Sometimes I have to write things down to see them and

           | same. But recently I also learned that my wife just sees
           | words when reading a book whereas I see a "movie".
           | 
           | Also I will project words in my mind to inspect them visually

           | biology.
           | 
           | But from this thread I still get the idea there are people
           | that really really see things, whereas for me it stops at
           | "visualizing". Which does help when composing a picture but

           | 
           | One weird thing I often did (or try to do, doesn't always

           | until I sort of got convinced there was a massive boulder
           | looming over me. It would feel quite real and I'd really feel
           | the massiveness and it would make me feel very small and even
           | make me feel adrift. Strange, this thread actually made me
           | remember, didn't really do that for a long time now.

           | I think I'm the same. It's as if I can imagine a geometry,
           | but it doesn't have any texture or colour. It's not black,
           | not grey, not brown... It's a shape in its pure form, maybe

           | 
           | However, I can imagine music and actually hear it. I had this
           | a couple of times where I "replay" a song in a foreign

           | parse out more lyrics than before. All inside my head.

             | But familiar music can be played back in my head with only

       | Rubbing your eyes doesnt make you not aphantasic, any more than
       | looking at a bright lightbulb for a few seconds or unblinkingly
       | staring at a single image on a bright tv for a few minutes (which
       | is actually more effective if you want to clearly see colorful
       | and bright shapes with _closed eyes_ -- doesnt change your minds
       | eye, which is different), and whats worse is that it will damage
       | your eye!

       | 
       | But, is that seeing images in your head, or isn't it? Must you

       | say they can visualize.

       | A bit OT: I'm curious what, if anything, people here see when

       | 
       | I usually see one of the following:
       | 
       | 1. Just the brown/black of my eyelids, with some slight
       | variations in darkness.
       | 
       | 2. A blob of white light. It looks a lot like what you'd see if
       | you were in a dark room with a sink full of water that is
       | draining, and there was a drop of some glowing dye in the water
       | which is circling the drain and expanding.
       | 
       | 3. Gears, pistons, linkages, pulleys, wheels, etc forming
       | elaborate moving mechanisms. I have no idea what the mechanisms
       | are doing or if any of the mechanisms are sensible or even
       | possible. I'm very much not mechanically inclined and so this is
       | the most puzzling nighttime visualization to me.
       | 
       | 4. Plants. I seem to be flying low over land with patches of
       | grass, flowers, and trees. The scene is quite detailed, with
       | individual leaves and blades of grass visible, and any gaps
       | between things filled with things farther behind, giving a strong
       | sense of 3D.
       | 
       | 5. Animals. Unlike the plants of #4 that I see in a full
       | environment if I see animals they are just kind of there against
       | the brown/black background. Sometimes they are normal animals,
       | and sometimes they are weird creatures that belong in science
       | fiction or mythology. The animals often morph into other animals.

         | Not Zen, but there's "kasina" meditation that sounds similar to
         | this. You might stare at a light source or a colored disc, then
         | close your eyes and watch the afterimage. Repeat. That's it
         | really - very mechanical.
         | 
         | That can lead to wakeful closed-eye hallucinations, some of
         | which are described here:
