Can you visualize things in your mind as if they were physically in front of you? People with aphantasia cannot and they often can't remember visual events from the past as a result. Perhaps you have it too.
It's not very clear as I can't really see it in front of me, but it's in my head, and there's a different kind of "seeing" happening...
One evening I asked my 5yo daughter that when she imagines something in her head, does she see it almost like in real physical 3d? She said yes. I wouldn't say yes to that question. But again, it's so subjective...
I’m fairly normal in most other ways, mentally, with really high (tested) spatial reasoning, and a good-but-nothing-special (on HN, anyway) tested IQ.
Just badly deficient autobiographical memory.
I didn’t even realize there was anything wrong until my mid 20s. Turns out this is a relatively-recently-discovered disorder of some kind, and on reading accounts by people who have it, I was like “…oh.” Not super well studied, I think in part because it tends (incredibly!) not to actually impair living an OK life. You just don’t really remember it like a normal person does.
