Anyone ever hear of this? Apparently it's a neo paganism thing where people identify themselves as non human but rather as a spirit, animal or dragon or something like that. There's actually a reported cases where people identify as dragons, eat only gems and rocks and die. Perhaps on a related note due to the identity issues of the transgender community, apparently there are a LOT of transgender otherkin.
Learned about all this from a friend who is transgender, otherkin and vore (sexual fantasies about being eaten).
The world is an interesting place.
