I do, but I haven't practised the skill much lately so it's not as vivid as it used to be.

It's more like a second virtual desktop than superimposed; it takes up the same coordinates, but there's a clear distinction between "real" and "imagined" objects (unless I'm particularly tired, but that's closer to "hallucinating" than "visualising").

I used to be able to visualise things in positions relative to real objects, but at the moment I can only manage floating in the air, such that focusing on the position of imagined objects de-focuses the background, either relative to my field of view (so it moves when I move my head) or in a defined position in space (so it doesn't move when I move my head – though obviously this is limited by my ability to instinctively judge positions and distances, so it often doesn't quite work right when things are moving in complex ways, or I'm moving fast).

That's blowing my mind right now. First I thought people who can visualize to the point of actually seeing what they visualize were pretty rare. For me what I visualize takes place in a mental space: it's a clear mental image, not a literal visual image.

Have you always been able to do this, because you mention practising this skill? Also, does this only happen after focussing on something, or does it happen spontaneously when thinking? I imagine it would be pretty distracting if someone says for example, "don't think of scary thing X", and then the scary thing manifests visually for you because you are thinking about it.

That sounds about right. For me, "don't think of a pink elephant" results in the image of a pink elephant, though if I'm not concentrating on its location it's just… somewhere.

I think I've always been able to do it – but I haven't been doing it as much since I stopped playing with toys, going outside and generally doing activities where such a thing would be useful, so it's less instinctive.

Uh yeah, same here. Like, I can remember what my daughter looks like as she sleeps in her crib, but visually what I see (with my eyes closed) is just blackness. I've always thought of it as something akin to a prerendering buffer or virtual display context in my mind. What the parent poster is saying makes me think that for them its more like experiencing an actual display, which seems like it would get really confusing layered onto the visual input from their eyes.

The only time I've ever experienced anything like that I was trying psychedelic mushrooms for the one (and so far, only) time, and so it was literally a hallucination.

That's an excellent analogy! The mental space is exactly like a prerendering buffer. When asleep and dreaming, there is no overriding visual input, so the stuff in the mental space gets rendered. And I guess some people can access this even when sensory input is present. That must be wild.

I had many conversations in the weeks following my original discovery, and this comment thread reflects them perfectly.

Me: There's no way everyone actually sees things and I made it 30 years without knowing.

Everyone else: Yeah I see things.

Me: but, like really see or just remember features?

Everyone else: <some variation of quality, but it was always described visually and everyone agreed it was basically like seeing>

I put "see" in quotes in my original comment simply because that is how everyone I spoke to described it; that it's clearly not physical vision, but it's also clearly a visual experience. I have absolutely zero visual experience when I close my eyes, and I never have, it is simply emptiness.

You seem to describe dreaming as if you experience that visually too, while not being able to do it while awake. It's worth noting that this is not uncommon for people with aphantasia, which is why it is the inability to _voluntarily_ invoke your minds eye. Many people can still dream visually, however I do not. I go to sleep and then simply wakeup with nothing but emptiness in between (not an experience of emptiness as time passes, but more like a time skip).

Yep, imagining/visualizing something goes without an actual visual experience for me. I've always assumed the same thing applies to most people, but I guess I do have some degree of aphantasia.

I can imagine something, but it's like rendering a layer with the opacity brought all the way down to 0, but my "mental computer" knows it's there and can tell its shape, color, all its features & details in 3D space... without seeing the actual visual image.

Dreaming on the other hand is usually multi-sensory and especially visual for me. Much like being awake or in a VR environment, but with internally generated input.

Have you spend time really consciously investigating your sleep? To the point of interrupting it with alarms etc..? I'm someone who's very interested in my dreams: for years, every night before sleep I wonder what I will dream, sometimes I get lucid during the dream, and when I awake my first instinct is to recall my dreams. I think this is why I dream so much. I wonder if the same thing applies to visualization and whether or not aphantasia is "curable" through consciously exercising visualization.
