The Baku, or Dream Eater, is a fantastic, chimera-like beast originally from China. It is described as having the body of a bear, trunk of an elephant, eyes of a rhinoceros, tail of a cow and legs of a tiger, with a spotted coat.
Despite its ferocious appearance, the Baku is a helpful spirit who can consume nightmares or bad fortune from dreams. It is also said to prey upon the spirits of disease and plague. The Baku is so well thought of, some place a Baku talisman beside their bed to protect against bad dreams and evil spirits. It is said if you make a bed from the skin of a Baku, it will keep illness at bay.
