Werewolves are part human, part beast. They reside in human form until the presence of the full moon, and then transform into a primal beast, that will destroy and ingest anyone and anything in its path. Because of this dual existence, werewolves are often thought of as an entity containing a dual personality. Because of the trauma that is induced from such a treumendous physical change, the human part of the werewolf often does not remember the change or even the events that have passed, and only suffer something of a "hang over" the next day. Some werewolves even live in complete ignorance of their disorder until the very day that they die.
