@Suck_on_my_Presence Jaws did, I lived near a lake. Took me a while to realize the lake was really much too small for sharks, but the movie gave me vivid dreams.

Alien terrified me, as the house I lived in had long dark hallways where those beasts or eggs could hide. Saw the film when video2000 and Betamax were still competing. I never found xenomorphs in my house and terror faded, but the franchise stayed with me including Disneyfication.

What actually scared me more was Poltergeist. What a terrifying world, house, family, setting, glow from behind closed doors and the TV sucked you in to the other side.

Return to Oz

Childhood trauma all over the place…

ET. I’d have nightmares so bad that my dad had to sleep in my room because I was so terrified of him (I’d dream he was walking on my bed). He still freaks me out!

To be clear, it still terrifies me.

I enjoy the rest of the movie but this is one of the greatest horror sequences ever. A remake that truly surpasses the original.

EDIT: I have to give a shoutout to the movie that had the most real world effect on me. That would be Arachnophobia. I couldn’t function normally for months. Sitting on the toilet. Putting my shoes on. Sticking my hand in a bag of chips. I was a wreck.

Volcano (1997) terrified young me. How could anyone sleep peacefully when lava could just appear out of nowhere?

Needless to say I never lived even remotely close to any kind of geologically active area, let alone a volcano.

The Evil Queen disguised as an old lady in Snow White

At the height of the cold war, 87 or 88 iirc, a movie came on HBO called Dreamscape. It’s WW3 imagery really blew my mind, I recall having dreams about it for ages. I’d turned it on because a few weeks before I’d really enjoyed Innerspace with the same lead actor, but this was a bit different lol

Yes, the danger must be growing For the rowers keep on rowing And they’re certainly not showing Any signs that they are slowing

TELL THEM LARGE MARGE SENT YA!

Darkness falls.

It’s a movie about the tooth fairy but the tooth fairy is actually an old woman who used to collect the teeth of the children in her village until the townspeople burnt her alive and then she became a spirit who was essentially the tooth fairy but if you ever saw her she’d kill you.

It’s cheesy as hell but it was terrifying when I was younger

Who framed Roger rabbit, the scene with the judge guy putting a shoe cartoon into the acid barrel.

Terminator 1

Listen, and understand! That Terminator is out there! It can’t be bargained with. It can’t be reasoned with. It doesn’t feel pity, or remorse, or fear. And it absolutely will not stop… ever, until you are dead!

This fucked me up more than any monsters… This thing just has one mission and it’s relentless

In hindsight, it was irresponsible to watch Robocop as a 10-year-old.

Gremlins, when they transformed

It wasn’t a movie per se. I thought it was when I was a kid, though. It’s an episode of “Friday the 13th: The Series” called “The Executioner”.

I was like maybe 6 or 7 at the time.

It starts with this guy in prison you see them take him to the electric chair and attempt to execute him. They botch it and the warden or whoever pretty much goes “oops, well by law we did technically carry out your sentence so you’re a free man now”

He then goes on to become a dentist and uses a “cursed electric chair” as his dentist chair to take revenge on the world.

This gave me a real fear of going to the dentist on top of just being a kid and being scared to go. Still hate going to the dentist (who doesn’t I guess)

I used to play Myst at the time and that even made me feel uncomfortable in the Time Machine room with the dentist chair at the first island.

edit: I watched it again as an adult and it was corny as hell
