How clear are the pictures normal people can visualize. Is it like seeing but with your eyes closed? Because what I can do is nothing like seeing. Visual memory doesnt appear like a vision. Just a vague memory. Can people actually see memories. I'm really missing out if so.

I'm baffled as well. I had no idea people could do that. I thought that was called hallucination. I can remember images, I can't see them. I think I'm missing the point somewhere.

Wow, I finally have a word to describe my mental experience. To others, I've described the vividness of my memory as like a wireframe. I can feel spatial relationships but I don't see them like a picture in my head. There are occasions that I can see color in my minds eye, but it's mostly greyscale.

How do you dream?

Rarely with any color. Mostly about moving through terrain and spaces, but the sensation is only partially visible.

I wonder if you can improve your visualization ability.

I stopped reading novels for fun about 5-6 years ago but this past year I've started reading at least one book every couple of weeks, and I feel that my ability to visualize things has improved.

On a related note, I wonder how you could measure one's change in visualization ability, since it's so subjective. I had a very difficult time answering the questions in the article, since I had no frame of reference.

I stopped reading novels for fun for about 4-5 years and this past year I've started reading at least one book every couple of weeks, and I think my ability to visualize things has improved.

> Close your eyes and imagine walking along a sandy beach and then gazing over the horizon as the Sun rises. How clear is the image that springs to mind?

Very clear; I see some cons cells, making up a list, whose CAR holds the symbol BEACH, the main connective of an abstract syntax tree describing the whole situation.

There was an interesting subthread on this, on another article entirely, a while back:

Meanwhile, I once answered a question from a person on Quora whose premise was that people can imagine "audio and visual" stimulus, but not "odor, taste, or touch". I suspect that was based on the asker's own peculiar dominant senses and style of memory, as I addressed in my answer:

i used to have this ability. i know i had it as a child. i remember visualizing fantastically complex systems. i seem to have lost it at some point in adulthood. i have no idea when. i started doing it again while using drugs, and this caused me to become aware that i'd lost an ability i once had. it was very hard to explain to people what this ability was, but i rememberd being able to visualize fantastically comple…

Of course insights from drugs may not always be fully reliable, but what drug did you take, and did you try taking more?

Almost everything gets better with practice. Memorization experts have often used visio-spatial 'memory palaces', imaginary places they can fill with items to remember. Simply trying to use that technique might help build visual recall flexibility.

Perhaps it'd separately be worth trying a sensory-deprivation soak-tank?

Yeah, that's a good way to put it. I can "feel" myself navigating my house in my mind, can draw a floor plan, etc., but I can't picture it. More like knowing "I can expect a chair there, or a wall there" or whatever.

I kind of suspect it might be similar to how blind people experience "visualizing" something where they've got the contours well-mapped in their head, but of course I have no way to know that for sure.

Yes. I find that when I imagine a scene there might be a lot of details missing without extra effort to imagine them. If I imagine a beach I might immediately get a detailed convincing image just like watching a video clip, with waves, birds, etc, because beach scenes come to mind very easily. But if I have to visualise some vague memory or novel scene I do get a very vague impression that isn't really an image at all. If I ask myself: "what's the carpet?", "what's on the walls?", etc, I can slowly add details until I get a proper image by piecing together memories.

On the other hand I am very bad at recognising people or visualising faces! Even if I try to visualise my own face or the faces of my parents or a celebrity like Bill Clinton I get something that's very uncanny, distorted and missing details. The part of your brain for recognising faces is signicant in size and very specialised, so it makes good sense that you might be able to visualise faces but not other scenes or vice versa.

BTW, I am a VERY visual thinker, I even do algebra in my head by imagining equations floating in space in front of me and moving terms around "physically". But I'm not an extrovert. If I can't visualise something (e.g. much of abstract algebra) I'm hopeless at it.
