I HATE horror films, but when I was about 15 and just seriously getting into religion, I decided to watch The Exorcist (the 2000 edition) on my own. At 1 in the morning, with the lights off. I had nightmares for months, and when I was watching it I kept looking over my shoulder just to check that there was'nt some freaky 9 year old in pyjamas with green eyes standing behind me.
Torture for me is not cutting my bollocks off - it's having to watch The Exorcist on mushrooms.
