As a Christian who believes in spirits, demons, angels etc. I am fucking terrified of demons. I have grown out of my fear of monsters, zombies, ghosts, and all that shit to be honest. But the one thing I'm still afraid of is demons, simply because there's a good chance they could be real. I can watch any horror movie, about murderers, torturing people, gore, monsters, creatures, ghosts or whatever, and I'll sleep a good night's rest without fear. But if you show me a good scary movie about demons haunting somebody/a family, I turn into an instant pussy.
