So this doesn't necessarily have to be violent or even real I. E in movies, tv shows etc but what image/s is burned into your mind and hasn't left you?
As a kid in junior School this boy was running fast tripped over smashed his mouth on playground. He was screaming blood and teeth everywhere. Still see the teacher picking him up blood going over her light coloured coat.
Weirdly another image that has stuck in my mind is a scene from snakes on a plane. Where huge Python wraps around the guy and eats him head first. Snakes are my phobia without doubt and that movie is so silly but that scene has stuck with me more than any other, even more brutal movies.
