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.
It's very sensitive to attention/intention: asked to visualize a person, I'll mostly imagine the face and general build – not even picking specific clothes – unless that person is very associated with some outfit. But if I think more about some specific prompt – say, "what were they wearing at some recent event", or "think about their hairline" – I can call up (or pick) reasonable details.
I suppose you could say it's no more vivid than it needs to be, and with concentration it becomes more vivid/detailed, but never quite like the solidity of a photograph. (Well, maybe while deeply concentrating with eyes closed, or half-asleep, or actually dreaming, there can be moments of seeming realism...)
