Voodoo

Voodoo is a mysterious religion practiced in Haiti and Brazil, whose origin seems to be the Guinea or Dahomey. Voodoo ceremonies are under the protective deities (beneficial or evil) and this practice of using animal sacrifices (chickens, goats, sheep and birds).
After absorption of a beverage prepared by the high priest, the followers begin frenzied dances that lead to the trance state. The high priest has the power to resurrect the dead who are thus transformed into Zombies. Wes Craven has directed in 1987 a very interesting horror film on the subject of Voodoo: The Serpent and the Rainbow, cleverly mixed with political intrigue on the Tonton-Macoute.
