A zombie is a dead person that is brought back to life through a curse (voodoo, necromancy) or a mutation and has recovered some vital functions like movement.
They are near-mindless, possessing little reasoning power, though many can perform "remembered behaviors" from their mortal existence.
Zombies are omnipresent in the folklore of Ha´ti, where they are created by voodoo, an african type of black witchcraft. More recently, zombies films have exposed new theories according to which man-made virus or genetical experiments are held responsible for the creation of zombies. Such films put a strong emphasis on flesh and blood : rotting bodies and their attendant maggots, as well as the still-warm gore resulting from savage, often cannibalistic attacks upon the living.
