Otherkin is a subculture of individuals who identify as partially or entirely nonhuman. An umbrella term for this would be alterhuman. Some otherkin believe their identity derives from non-physical spiritual phenomena, such as having a nonhuman soul or reincarnation. Some otherkin give non-spiritual explanations for themselves, such as unusual psychology or neurodivergence, or as part of dissociative identity disorder or being plural. Many otherkins say they are physically human, but not all.
