I was forced to go to a charismatic church as a kid. We're talking speaking in tongues, cast out demons, and all that bullshit. As such, The Devil was present in a lot of my childhood fears.
I was convinced I could feel him breathing on my face at night in bed whenever I did something "wrong".
I hated this Santa Clause decoration that my grandmother hung in my bedroom window every year (we lived in first floor apartment facing the street). When the streetlamp outside of my window hit it at night it looked the head of the Devil in silhouette.
I hated it when my family watched Unsolved Mysteries or things like that because there was always a chance they would do a segment on demonic hauntings or shit like that.
Religious trauma is a hell of a drug.
