I would tend to use this definition for otherkin instead: Otherkin – An umbrella term that encompasses the belief that all or part of the personal identity is something other than human. This has been explained by mental wiring, past life memories, spirituality, etc. There are subgroups under this including, but not limited to, therianthropes, angelics/celestials, demons, vampires, fae, elves, dragons or walk-ins/multiples.

Maybe merge it with what you have?

Also, perhaps you'd like to include "re-awakening" along with awakening?

Re-Awakening – A term that I use to describe my personal experiences. I use this in place of “awakening” simply because I feel that I’ve always been different and that my otherkinness has always been a part of me. I did not “awaken” and become ‘kin, I was born this way and it’s an integral part of who I am and how I identify myself. Re-awakening implies becoming aware of something that's always been there.
