When I was young child attending a Methodist Church our pastor left to become a missionary in Brazil, he came back for a visit the following year. He showed the Church many Videos and audio tapes of demons being exorcised from natives. I remember the quiet hush of everyone watching and listening to these tapes, these negative spirits that would speak from the natives mouths, (and some of these natives were still children) watching this would send chills down your spine. I do remember him telling us that all that were involved had been practicing with negative voodoo.  The local witch doctor had control of most of the village there. I also remember him saying that one young male had more than ten spirits living in his body, the boy was very very ill until they were removed.  linn
