The undead are beings in mythology, legend, or fiction that are deceased but behave as if alive. Most commonly the term refers to corporeal forms of formerly alive humans, such as mummies, vampires, and zombies, which have been reanimated by supernatural means, technology, or disease. In some cases, the term also includes incorporeal forms of the dead, such as ghosts.
