Most interesting thing I learned about myself in the last decade (thanks to that one post by the Facebook guy): I have aphantasia, which explains like 90% of my thinking.
So! I’m pretty sure I have hyperphantasia ... and I’m fairly sure I don’t have a milk voice :)
I was actually quite relieved when I found Einstein’s description of how he experienced thought:
Amazing! Do you also not have memories or is that just him? I would have thought factual memories would still be possible. "I had eggs for breakfast." "I was friends with So-and-So in college."
