3. Demonophobia
This is one of those fears where the name makes it obvious what the fear is of. Demonophobia is an irrational fear of demons and everything evil that hides in the dark. While everyone would probably be afraid if they saw a real demon only a demonophobe would be so afraid that they worry about running into one and would be afraid to spend time on their own or watch a scary movie, just in case.
