Demonomania is a noun that refers to an obsession or fixation with demons or evil spirits. It can also refer to a mental condition characterized by a preoccupation with evil or malevolent beings. The term was originally used in medical contexts in the 17th and 18th centuries to describe a supposed disease in which a person believed themselves to be possessed by demons. In modern usage, the term is often used in a more figurative sense to describe an intense and irrational fear or fixation on something considered evil or malevolent.
