OK, I had a story idea, of a girl who grows up feeling convinced that deep down, she's not human, she's a vampire. Then she finally meets a vampire, and convinces him to turn her. I'd envisioned her feeling similarly to a transsexual character, except it's species rather than gender that she feels confused about. But then when I tried to research otherkin, I get all this kooky stuff about reincarnation and souls and such. Do you have to have weird new agey religious beliefs to be otherkin? What would it look like if she was otherkin but didn't believe in souls and all that stuff?
