The original place where zombies come from African lore. Zombies are someone who was under the control of the magical will of the sorcerer. Today it means a dead human with no soul. The word zombie comes from Kongo Zumbi or zombie that means fetish or enslaved spirt. One story told by Jan Knappert in Natal.
A Zulu man called Sipo told how his brother Vamba who became ill and walking like an old man. He shortly died and his body did not go through the normal process of the dead with rigour mortis of the body was soft. Sipo was uneasy by this and thought this was the work of magic. The next day after being buried Vamba grave was opened and the body gone everyone knew that there this was work of the magic. Sipo went searching for a powerful sorcerer in his homeland. Eventually, in hushed tones, one particular person has pointed out to him an influential man with a large farm. Sipo waited at the gate until dusk at this time the people stop working and went home. Sipo saw an army of silent workers shuffling in the fields. The workers were silent during working. Sipo saw his brother and he went to him and saw his grey face and could not talk his tongue was slit. Sipo brought his brother back home and Vamba died again shortly and his body shows the process of the dead body.
