And West Virginia University Religious Studies professor, demonologist and history buff Dr. Alyssa Beall runs down how humans have used myths and stories to explain the feelings that make our hairs stand up and our stomaches sink. Is possession a mental illness? Are demons pranksters from hell? Is your baby evil or just cranky? And why do we like to be scared and poke at the line between life and death? Also: demon dongs. Oh wow.
