…what does it mean if you keep feeling like a fictional character? I don’t mean thinking you’re a specific character, like otherkin stuff, or even identifying a lot with a specific character. I mean like, thinking-I’m not Karkat or Katniss, I know that, but I’m not any more real than Karkat or Katniss. Maybe even less real, because loads of people know who they are and hardly anyone knows me. I’m just some shitty-ass OC by an unknown author, that somehow tricked the world itself into believing I’m a real person. And at any moment the world and the people in it might suddenly realise it’s a trick.
Nngh, sympathy and witnessed, because I find I need to specifically avoid that line of thought entirely. (For me, it's "what if I'm just someone's RP character?" which leads to being unsure if anything is really-real if I let myself go down that rabbit hole. Also to being extremely unhappy with / hostile towards my hypothetical mun.)
"i'm not real" in any iteration generally maps onto the concept of depersonalization, or more broadly dissociation
