There are many references to ghosts in Mesopotamian religions - the religions of Sumer, Babylon, Assyria and other early states in Mesopotamia. Traces of these beliefs survive in the later Abrahamic religions that came to dominate the region.^[23] Ghosts were thought to be created at time of death, taking on the memory and personality of the dead person. They traveled to the netherworld, where they were assigned a position, and led an existence similar in some ways to that of the living. Relatives of the dead were expected to make offerings of food and drink to the dead to ease their conditions. If they did not, the ghosts could inflict misfortune and illness on the living. Traditional healing practices ascribed a variety of illnesses to the action of ghosts, while others were caused by gods or demons.^[24]
