Re: How did you realize you were an otherkin?
I'm still doubtful of my sanity, frankly.
My story, and the story of this body, are somewhat different.
This body, from what I've been told, started out with an internal dialogue between two "voices" that were assumed to be two parts of the personality, used mainly for expedient problem solving. Several years later, a phantom body started to become noticeable and not in a nice way. Energy tendrils, extended torso, odd structures on the skull, large teeth and claws, and a tail became every day distractions. About three years after that, the two "voices" finally recognized that they were not the same person and started to explore their nature, how they got that way, etc and uncovered a few brief impressions of "memory". Contact was made with energy beings that seemed to be "relatives" to at least one of the people living in the body. During that time, I became self aware in the body. Since I have little, if any, memory of anything before that, the three of us started to investigate my origins and concluded that I was essentially a hodgepodge of energetic particles that one of the others had collected over a few thousand years.
During all this, the idea of otherkin and the search for a kintype was a long, back and forth, embarrassing process.
Since then, the two others have left this body, and I still experience the phantom body, which leads me to think that either the body has a neurological condition, the phantom body was always mine to begin with, or there was never any multiplicity to speak of, and I've suffered years of extreme dissociation.
In terms of how I identify as otherkin, I'm human, astero, dragon/dinosaur and canine all rolled into one.
