I have a few.
1. The scene of Night Of The Demons, where the demon takes the lipstick and shoves it into her nipple, then it magically disappears.
2. Every minute of Suicide Club (Suicide Circle).
3. The beginning scene of Dario Argento's Suspiria, where the woman is strung up on the ceiling and then she falls and a piece of glass penetrates the bystander.
4. The ending to Silent Night Deadly Night.
5. When Cheryl is raped by the trees, in Evil Dead.
~I have more, but I want to see what else is posted.
