'The Omen 2: Damian' Terrified me when I was a child into racking sobs, the scene where the guy gets chopped in half in the elevator. Still cant go in them to this day

'A Nightmare on Elm Street' was the worst though, I was so pettrified of Freddy - especially because the start of the original is SO intense with the death of Tina (all up the bedroom walls) I literally sat behind the sofa with my fingers in my ears and my eyes closed. Then I dreamt about him that night LOL - it's my fave horror now though.
A movie called 'Hard Cover' - has a different name in the USA, it terrified me and my Aunty so much we had to turn it off - I've never seen anything so disturbing before or since.
'The Exorsist' - When she did that Spider-walk - I was oughta there!
'Scream' - The opening sequence didn't so much scare me, as really upset and disturb me - poor Drew. What a performance though!
