Zombie is a term used to denote an animated corpse brought back to life by mystical means such as witchcraft. The term is often figuratively applied to describe a hypnotised person bereft of consciousness and self-awareness, yet ambulant and able to respond to surrounding stimuli.
According to the tenets of Vodou a dead person can be revived by a bokor, or sorcerer. Zombies remain under the control of the bokor since they have no will of their own.
Zombie fiction is now a sizeable sub-genre of horror, usually describing a breakdown of civilization occurring when most of the population become flesh-eating zombies – a zombie apocalypse.
The monsters are usually hungry for human flesh, often specifically brains.
