I can basically do a Google Street View of places I’ve been before, seeing what I’d be seeing if I was there. It’s not as clear as being there and having my eyes open, and th animation is jerky, but it’s in color, and I have the same spatial sense of where things are relative to where I am mentally standing.
For the most part, I can’t “think” about things except maybe mental math. I see things, and I talk to myself in my head.
