Nightmare on Elm Street (the whole premise)
Poltergeist (The Clown Doll scene)
The Ring (When she climbs out of the TV)
Ju On (goosebumps throughout)
Blair Witch (very personal kind of movie - I couldnt imagine going camping anytime soon in a remote place after that...)

for adult movies, Manhunter was one of the scariest for me when I saw it.

Another vote for The Exorcist. It was quite an unnerving experience back in the day.

And so was Frankenstein. I never saw the uncensored version until the DVD release a few years ago. Karloff's encounter with the little girl at the river is horror sublime. I've always been a big fan of the old Universal horror classics.

the evil dead

I was 10 when i saw "Ghost Story". I had nightmares for weeks, I still can't watch it if it's on tv. 22 years later!

Children of the Corn...

That music creeps me out.

I remember losing a few nights sleep after seeing "The Wizard Of Oz" when I was little.

"The bad monkeys are going to get me."

When I was about 12 years old I saw the 1960 version of H.G. Wells' The Time Machine on TV. The film came to a part where the world of the far future had evolved into a peaceful, idyllic, pastoral Garden of Eden with beautiful people (the "Eloi") who seemed a bit stupid but nevertheless happy. I figure I must have started the puberty process by then because Yvette Mimieux was oozing sexuality (remember, it was filmed in 1960) and I was smitten. ;) http://www.nndb.com/people/783/000043654/yvette4-sized.jpg

All of a sudden an awful sounding siren-horn starts blaring and the Eloi drop what they are doing and mindlessly congregate at a strange rock outcropping, at which they enter subterranean entrances and flock inwards. When I caught on to what was happening it totally freaked me out: the Eloi were nothing more than cattle being summoned into the Morlock slaughterhouse!!!! That really, really got to me and I had nightmares for weeks.

Four creepy John Carpenter movies - Halloween, The Fog, The Thing (Remake), Prince of Darkness

The Changling

Two for me in particular:

Black Christmas

It came out some time in the 70's, I saw it when I was young and I still look up when I walk by the attic.

Open Water

I simply lived in this movie the whole time it was on. I felt like I was there and couldn't imagine what it would have felt like to be left in the middle of the ocean.

Ah yes, Black Christmas. Watched that one by myself. Big mistake. Canadian movie too that really set the tone for the genre (sorority house and killers). Yep. Good one!

Some movies that gave me nightmares were;

1. PHANTASM

2. Carrie

3. The Exorcist

When I was younger Boris Karloff and Peter Cushing movies frightened me.

Two movies that scared the life out of me as a kid were:

1. "Lassie Comes Home" - the scene where they captured Lassie by throwing a net over the dog, but the scene was shot with a net being thrown over the camera.
2. "The Egyptian" - the scene showing a newly-constructed pyramid being permanently sealed with a lot of people still inside.
I think that's when I began suffering from claustrophobia.:(

Burnt Offerings, with Oliver Reed and Karen Black.

When I was 14 my cousin and I saw this at the theater back in 1976. Some people thought it was a silly movie but the chauffeur scared the hell out of me.
I had very bad nightmares about him that night. Brrrr.
Once in a while the movie shows up on TV but I still avoid it. After almost 30 years that damn chauffeur still creeps me out.

I did feel vindicated though, after posting my own review at Amazon.com and seeing there were others who were affected the same way....

Strangely enough, "Saturday The 14th".

I watched it when I was 5 (Almost 6) and the scene with the monster in the closet scared the piss out of me. For years after that, I could not sleep with the closet door open.

The Changling

I have to second this one. I saw this movie as a kid in the theater and remember actually screaming at one point! HAHA. Crazy Kid. But yeah its scary-spooky-ghost story.

I'm surprised that no one has mentioned any of the OMEN movies. I always thought the OMEN I and II were pretty scary, along with the Exorcist, Carrie and Jaws

Generally I have issues with zombie movies. But the most recent one that gave me nightmares was "The Ring." I'd be sorta half asleep, and all of a sudden think "did my TV just turn on to snow?"

I had to take my TV out of the bedroom for a week because of it. :eek:

Have to agree with "The Ring". Funny story about that. My girlfriend had just left earlier that week to be home for some family issues, so a bunch of friends took that opportunity to come visit me for the week. I was just days after having upgraded from a 20" Mitsubishi set to my new 46" Sony widescreen, and they wanted to watch some movies on it. Of course, one of them picked The Ring. So we watched it and then they left me all alone. With my big TV.

So yeah - that was one of the first movies to be watched on my new big screen. For weeks I couldn't stay up past 10:00 or so watching. I got over it. :)

Poltergeist...(mooommmie)...that tv screen still freaks me out

Nightmare on Elm Street (the whole premise)
Poltergeist (The Clown Doll scene)
The Ring (When she climbs out of the TV)
Ju On (goosebumps throughout)
Blair Witch (very personal kind of movie - I couldnt imagine going camping anytime soon in a remote place after that...)

I feel/felt the same way about all those movies too! :)

The only differences were with Nightmare on Elm Street, the part that creeped me out was when he was in the alley way chasing the girl (who gets gutted) and his arms reach all the way to the walls of the alley.

Other movies that gave me the creeps back then were:

Deadly Blessing (scene where a girl is sleeping and her mouth is open and a spider falls inside)
Carrie (the end where her hand comes out of the grave)
The Shining (watched this entire movie by myself when I was 10)
