#5 Ahmad Suradji
The Indonesian serial killer admitted to murdering 42 girls and women from 1986 to 1997. His murder spree was prompted by a dream, where he claims his father told him of a ritual that would make him a mystic healer.
According to the dream, if he murdered 70 women and drank their saliva, he would be granted powers. He used his status as the local shaman to lure young girls and women. After murdering his victims, he buried them in a sugarcane plantation near his home, with their heads facing his house — an act he thought would give him more power.
