There's probably plenty of identical threads to this, but I was wondering - What was/were the scariest moment(s) in your life?
One of mine would be when I was watching Derren Brown's Seance. Throughout the show, my wardrobe door was shaking and rattling. In the show, something made the participants scream and at that point the door started shaking violently until it burst open! I nearly shat myself and was still screaming when i realised it was my big brother who'd been behind the door.

When my apendix burst, I was lying there normally, all of a sudden, I scream, well, I THINK it was scary.

Being shot.
