Most Disturbing Scene in Fiction

[blackrave]

A Serbian Film. What part, you ask? Well, I would answer that but I have blocked out most of memories surrounding the film. Just look up the synopsis.

It's hard to pick one moment, I think you can safely say that it is whole movie
Must ask what you used to block the memories?
I've heard drinking a glass of cold, refreshing bleach can do a trick, but I'm a bit scared to use this method, due to harmful side effects.
