I was hyper-visual and had a photographic memory before losing all my vision when I was 29, so I recall visual memories all the time. I can replay whole movies and shows in my head at a moments notice, and I tend to need a visual description of things just so I can visualize it in my head before interacting with something. Always curious about how people look, and I actually come up with my own color map of my surroundings. Like I tend to just have a feeling that a surface is a specific color to differentiate it from other things around me, and I'm always surprised when someone with vision tells me the actual color of the thing and it goes against the color that I've inadvertently assigned to it.

My mind also loves creating vivid detail based on audio description and filling in the blanks with movie and show scenes I've watched after going blind, and it's gotten to the point where I have a hard time remembering if I've actually physically seen a specific scene or not since I have such a detailed version of it in my memory, complete with color, effects, compositing and blocking, character expression and action, then I have a super wieerd feeling when I find out that it was all from something I saw after going blind. It's a bit of a trip, especially when discussing scenes in great detail with my partner or friends with vision and figuring out how much I got right with my own mental mapping of a scene versus the actual visuals.

I think this is a sign of creativity and of being a visual thinker. Maybe it might be a bit of synaeathesia too.

Yes! Hell yes, and I recognise a lot of things that other people have said here.

I have been told that when I went blind some of the people I knew really well were told to keep talking about how the world looked on the basis that it helps to keep the memories alive. They did that and it was honestly torture, it was like being teased, I hated it. I had been very very visual, I was training to work in television camerawork, and being told what the world looked like was depressing. I have done the same thing with some of the people I mentor and they don't like it either, you have to be careful how you do it, but it has benefits long term.

The thing is it worked and just like you I have what feels like completely vivid memories of what things look like. I guess it's possible at this stage those memories are rusty and wrong but it doesn't feel like it, and as much as possible what's in my head seems to jive with the reality everyone else lives in. I was older so maybe it's easier to do that but it's not something I would ever want to lose.

I’m glad I’m not the only one who does this :P

Yes, I tend to do this when it’s something I can’t see or can’t see very well. I try to recall what it used to look like when I could see better.
