I do have a mind’s eye, and quite a capable one apparently. I’ve seen some people say they imagine in flat shades or even in black and white, I can imagine and remember things as clearly as I can see. I can imagine the cross section of an engine running. I can’t vouch that my mind correctly models firing order and timing of an engine of more than two cylinders but if I focus on one cylinder the details are right.

I also have quite a capable mind’s ear. Pretty much all day I hear my thoughts in my head as if they’re being spoken, I can also imagine music. I just tried it out by imagining the Top Gun anthem as played on the SNES’ sound chip with that orchestra sound that was used on the console quite a lot. Not a problem.

It utterly fascinates me that some people outright can’t do that.
