I can’t generally “literally see” my mental images. But on a few rare occasions in my life, I did. I don’t know why, and it was brief, but at least I can easily believe now that some people do it all the time.

When it happened to me the few times it was an otherwise very mundane day and it felt very natural. It was overlayed onto whatever else I was looking at and could persist with eyes closed.

Honestly the experience kind of cheapened art for me to an extent since you either have that cheat code or you don’t.
