“Possession, he matter-of-factly explained, is the fourth stage of demonic activity. First comes encroachment, where a negative spirit is given an opening to a human being, either through voluntary means, such as a satanic ritual, or through involuntary means, such as a curse or the performance of an unholy act. The second stage is infestation, when the demons first haunt a person’s house. The third stage is oppression, when the spirits begin trying to take over the person living in the house. The final stage, after possession, is death.”
