When I was young I decided to scare myself by reading The Exorcist while listening to Black Sabbath's first album in a candlelit room with some herbal helper. It worked.
Later I saw the film and was suitably terrified. A few years later I visited a friend and he had The Exorcist video on while chatting with some others. He was pretty loud and I asked if he could tone it down while I watched the movie - I never forgot his reply: "Who cares? It's just a girl in a room going GRARRGH the whole time".
I tried watching again but the spell was broken. Turned out it actually was just a girl in a room going GRARRGH :)
