The aphantasia test: imagine a person rolling a ball across the table.
What color was the person's hair? If it didn't occur to you, you may have aphantasia.
(This ability, I assume, is key in reading books. It's like an ongoing movie in your head if you can do it. I can't.)
I do have a sort of movie playing in my head, but it’s not really a visual or auditory experience. It’s more like a running list of bullet points; a stream of facts. Visual descriptions are chock full of these facts, but they’re all usually inconsequential to the plot so I tune them out.
I find aphantasia very strange. I don’t lack a mind’s eye, but I do lack the ability to use it while conscious. My dreams are extremely visual and movie-like, but my conscious experience isn’t really visual at all. It wasn’t until recently that I learned “day dreams” are named that way because for most people they resemble dreams, but mine don’t at all.
I imagined what you said, but my thought was focused on the ball, and so the person was "unfocused", or "not as detailed" - I'm not even sure what gender they were.
Oh, and I'm colour blind (which is relatively common), so probably don't think of colours in the same way as others.
