80's for me, as someone else said being a kid when these came out has an effect.
Very few movies make me jump and outside of seeing Fall of the house of Usher when I was 3 or 4 (I'm told I had nightmares for a short period after) only one movie has really scared me. That would be In the Mouth of Madness. The special effects weren't good even for their day but something about the twisting of the mass perception of reality really got to me.
Notable mention for the end of Prince of Darkness when he turns over in bed. An 11 year old me and my mother were watching this alone in the house together on the love seat. That scene causes her to scream out, I screamed out, and the dog who had been sleeping on the floor beside the couch jumped up there with us. Wish someone would have been filming that sequence, I'm sure it looked as stupid as it felt.
