This is primarily an autism focused question, although allistics please do chime in if you have something interesting to say!
I’m not referring to stuff like Therians or “not feeling human”, although those are deeply fascinating topics. No I’m strictly referring to finding the task of imagining the human form (in say “daydream stories”) to be unpleasant/uncomfortable.
When I was real young I was REALLY uncomfortable imagining the human form. No problems with animals and weird creatures thought up by toddler me, those didn’t make me uncomfortable!
I brought this up with my IRL friend who’s also autistic. He also experienced something similar!
Anyone else also do this? I kinda want to just… Talk about it. It’s interesting.

supposedly it’s harder for our brains to make up faces, if you do the blind spot thing and get someone’s head in your blind spot the thing that auto-fills the blind spots fucks up and doesn’t do a face
the difficulty could be the issue for some people but it sounds like there’s more going on as well. acting is kind of like lying, maybe there’s something with that.
Personally I don’t have trouble thinking of faces, so I don’t think that’s the case for me here.
