I agree with all the above. Candyman for sure; couldn't look in a mirror at nighttime for months after that.
As a kid, probably as an adult too: Poltergeist clown scene, Poltergeist face scene, Poltergeist closet rescue, Poltergeist static tv scene, every Poltergeist scene with the old woman in it, Poltergeist closet tornado scene, well any scene in Poltergeist with wind and strobe lights.
I stole fizzy lifting drinks. :(
