Zombie

A zombie  can be either a fictional undead monster or a person in an entranced state believed to be controlled by a bokor or wizard. These latter are the original zombies, occurring in the West African Vodun religion and its American offshoots Haitian Vodou and New Orleans Voodoo.

Religion

West African Vodun

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. "Zombi" is also another name of the Vodou snake lwa Damballah Wedo, of Niger-Congo origin; it is akin to the Kikongo word nzambi, which means "god". There also exists within the West African Vodun tradition the zombi astral, which is a part of the human soul that is captured by a bokor and used to enhance the bokor's power. The zombi astral is typically kept inside a bottle which the bokor can sell to clients for luck, healing or business success. It is believed that after a time God will take the soul back and so the zombi is a temporary spiritual entity. It is also said in vodou legend, that feeding a zombie salt will make it return to the grave.

Haitian Vodou

In 1937, while researching folklore in Haiti, Zora Neale Hurston encountered the case of a woman who appeared in a village, and a family claimed she was Felicia Felix-Mentor, a relative who had died and been buried in 1907 at the age of 29. Hurston pursued rumors that the affected persons were given powerful psychoactive drug, but she was unable to locate individuals willing to offer much information. She wrote:

“

What is more, if science ever gets to the bottom of Voodoo in Haiti and Africa, it will be found that some important medical secrets, still unknown to medical science, give it its power, rather than gestures of ceremony.

”

Several decades later, Wade Davis, a Harvard ethnobotanist, presented a pharmacological case for zombies in two books, The Serpent and the Rainbow (1985) and Passage of Darkness: The Ethnobiology of the Haitian Zombie (1988). Davis traveled to Haiti in 1982 and, as a result of his investigations, claimed that a living person can be turned into a zombie by two special powders being entered into the blood stream (usually via a wound). The first, coup de poudre (French: 'powder strike'), includes tetrodotoxin (TTX), a powerful and frequently fatal neurotoxin found in the flesh of the pufferfish (order Tetraodontidae). The second powder consists of dissociative drugs such as datura. Together, these powders were said to induce a death-like state in which the will of the victim would be entirely subjected to that of the bokor. Davis also popularized the story of Clairvius Narcisse, who was claimed to have succumbed to this practice.

The process described by Davis was an initial state of death-like suspended animation, followed by re-awakening—typically after being buried—into a psychotic state. The psychosis induced by the drug and psychological trauma was hypothesised by Davis to re-inforce culturally-learned beliefs and to cause the individual to reconstruct their identity as that of a zombie, since they 'knew' they were dead, and had no other role to play in the Haitian society. Societal reinforcement of the belief was hypothesized by Davis to confirm for the zombie individual the zombie state, and such individuals were known to hang around in graveyards, exhibiting attitudes of low affect. In 1988, Wes Craven, director of the Nightmare on Elm Street horror series of movies, filmed The Serpent and the Rainbow, which diverges significantly from the book.

Davis' claim has been criticized, particularly the suggestion that Haitian witch doctors can keep “zombies” in a state of pharmacologically induced trance for many years. Symptoms of TTX poisoning range from numbness and nausea to paralysis (particularly of the muscles of the diaphragm), unconsciousness, and death, but do not include a stiffened gait or a death-like trance. According to psychologist Terence Hines, the scientific community dismisses tetrodotoxin as the cause of this state, and Davis's assessment of the nature of the reports of Haitian zombies is viewed as overly credulous.

Scottish psychiatrist R. D. Laing highlighted the link between social and cultural expectations and compulsion, in the context of schizophrenia and other mental illness, suggesting that schizogenesis may account for some of the psychological aspects of zombification.

South Africa

In some South African communities it is believed that a dead person can be turned into a zombie by a small child. It is said that the spell can be broken by a powerful enough sangoma.
