Origin: Native American (Plains Tribes)
Chichipischekwan (or Rolling Head) are an undead creature in the form of a decaying, fearsome head, that rolls around, trying to find victims (in some cultures), or to revenge the person who killed them (other cultures).
They are formed from a violent act of murder, usually a person killing their spouse in a particularly malevolent way. The head of the deceased then follows the murderer around until it devours them or causes their own death.
Some cultures believe the creature can be killed by drowning, while others believe it can only be killed by justice served to the killer, or by complete destruction of the head.
