i narrate to myself... a lot. sometimes out loud too, although less often if there are people around, or maybe as often except i try to turn it into a series of joking comments instead of just.. talking to myself. notably i don't have my own distinct headcanons for characters' appearances if they're in a text- or audio-only medium. i do tend to have some sort of vague idea of what i think people i talk to online look like if i haven't seen pictures of them, but usually it's based on their icons. i can't actually imagine reading a book/listening to a podcast/etc and having a unique idea of what the character looks like. same with voices for characters. my hc tends to be "whatever voice actor i hear first, as long as i like their voice." it's difficult for me to explain any abstract concepts relating to me in words unless i see other people's explanations and go "yes, like that, that is like me." difficult for me to conceptualize things articulately in general, but it's especially noticeable when i'm trying to describe a sensation or the way i do something or feel about something.
