“Your mother's in here, Karras. Would you like to leave a message? I'll see that she gets it.”
― Pazuzu , 'The Exorcist' (1973)
After combing through movie lists from IMDB to Reddit, I think I've created the most complete collection of horror movies that climb inside your skull and mess with your brains.

But I've also included horror films that rely on the disintegration of the human psyche, and films where characters begin to lose faith in what is strictly real.
