Otherkin are a community of people who identify themselves as non-human in all but outward form, contending that they are, in spirit if not in body, creatures traditionally associated with mythology or folklore. Belief in otherkin is related to the changeling concept. The therian, vampire, and draconic subcultures are related to the otherkin community somewhat, and are considered part of it by most otherkin, but are culturally distinct movements of their own despite some overlap in membership. Some may claim to be able to shapeshift mentally - meaning that they may experience the sense of being in their particular form while not actually changing physically. The existence of Otherkin is variably explained as being made possible through reincarnation, having a nonhuman soul, ancestry, or symbolic metaphor.
