Scenes that traumatized you?

Now obviously I mean that in a neutral way. But what I'm asking is, what particular movies scenes shook you to the core? Here's mine:

*The torture scenes at the end of Salo, or the 120 Days of Sodom

*The scene from High Tension where the mom has her throat slit and hand cut off

*The scene from the remake of The Hills Have Eyes, where cannibals first enter the mobile home and begin terrorizing the family

*The colonoscopy-bag-rip scene from The Angel's Melancholia. So gross and painful to watch. Makes me cringe everytime.

*The scene from the original Texas Chainsaw Massacre where that girl is placed onto a meat hook and then is forced to watch her boyfriend get dismembered

*The 'I saw her face' closet scene from The Ring. Well, okay, that scene doesn't bother me anymore nowadays. But as a kid, that scene messed me up.
