Everyone saw their share of scary movies as a kid whether we should have been allowed to or not. One scene that I remember really getting to me was in Poltergeist 2 where the guy drank the worm in the tequila, got possessed, and proceeded to vomit out the ghost. The Link
Now that I think about it, the scene earlier in the movie with the dog (which basically sets up the final scene) is pretty much just as disturbing, if not more. So it's quite possible that The Fly 2 had the two most disturbing movie scenes I've ever seen. And ironically the MPAA didn't even consider either scene to be the "worst" in the movie, since it was the head-crushing scene which almost caused the movie to get an NC-17 rating.
I'm a old-timer, so most of y'all won't even be aware of this flick, but when I was a kid I saw a Vincent Price horror movie called "The Tingler". As I recall, the basic premise was that right after death a portion of the dead person's spinal column could be harvested and it would have a life of its own. Lots of scenes where a lobster-like creature (a foot-long piece of spine) would go around strangling people. But the scene that got me was a scene where the black and white movie jumped to Technicolor for about 5 minutes: in a bathroom the tub is filling up with blood. Blood is coming out of the faucet in the sink as well. And if I recall correctly, a hand comes out of the blood-filled tub (a la "Carrie" where a hand comes shooting out of the ground). I was somewhere between 6 and 8 when I saw that...had nightmares for weeks.
There were several scenes in Halloween, but I'll go with the one where the boogey man (Michael Myers) is standing in the yard behind the clothes line when Jamie Lee Curtis looks out the upstairs bedroom window. I don't know why...that scene just spooked me. And the mini alien popping out of the guys chest in the original Alien movie.
Star Trek: Wrath of Khan. The scene where they put the bugs into the guys ears. Freaked me out for years.
the tree scene, clown and guy eating chicken in Poltergeist. the troll suckin the kids breath in Cat's Eye. scarred for a loooong time after watching those!
Man, some good answers in here. Thriller, Large Marge, Zelda from Pet Sematary are all great answers. More recently, the scene in The Ring where they open the closet to reveal the dead girl with the gaping mouth and rolled eyes. I saw it in a theater and jumped about 4 feet and yelled JESUS CHRIST. A little embarassing. The ending to The Mist.
god damn tunnel scene on Willy Wonka and the Chocolate factory all those damn midgets and flying monkeys in the wizard of oz.
I have to second the flying monkeys in The Wizard of Oz! Flying Monkeys The Wizard of Oz was aired on television annually during the 60's. I remember leaving the room when the flying monkeys appeared; I was 6 or 7. The Exorcist: when that movie came out there had never been anything like it. They handed out barf bags at the theaters. I was in 7th grade and we sneaked into the drive-in to see it. Scary **** for 1973.
the movie Communion with the scene where the alien peeks around the door. ****, still freaked out to this day.
children of the corn (trailer) had intrusive thoughts of someone killing my parents with power tools/ kitchen appliances for much of childhood because of this movie.
Well, I was a big kid, but the end of The Blair Witch Project. Imagination can be scarier than anything they could have put in that scene. I never saw the movie but I remember the trailer for Amityville Horror scared the bejeezus out of me.
