What character types in game are actually human?

Unless stated otherwise, all character types in the game are actually at their base level human. If you want that more specifically, the following character types are in some way or other human: dreamwalkers, elementals, protectors, psychic vampires, psychics, witches. Lycanthropes and half-demons have human blood and can be considered to be humans with extra bits, if you will. Spirits were human when they were alive.
