What was the most frightening thing thats happened to you?

The most frightening thing that's ever happened to me was getting bit my a dalmation in the third grade. He practically took my whole left cheek off. Almost all the way threw too. Lucky he left a very thin layer of skin left on the inside of my cheek. I can feel the scar inside my mouth and still till this say i get  scared of dogs. Well big dogs when they jump on me and stuff.
