Haunting of Hill House

"Haunting of Hill House on Netflix."

"Scary as hell."

"Bent Neck Lady makes the hair on my neck stand up on end every time."

"Same with the ghost looking for his hat. Or whatever was down in the cellar."

~ Pretend-Cucumber-711

Hereditary

"Hereditary"

"That one scene near the end in the dark bedroom…is essentially a reverse jump scare. Something is there the entire time and it’s just a matter of when you notice."

"Sent chills up my spine."

"That movie stuck with me for days."

Doctor Who/Torchwood

"I have two contenders, from the Doctor Who universe..."

"'Blink' from Doctor Who."

"'Children of the Earth' from Torchwood (all 5 episodes)."

"Both are the stuff of nightmares, but in very different ways."

"'Blink' will make you not sleep at night, while 'Children of the Earth' will deeply disturb you."

~ Common_Sense_Dudd

"The first few seconds I was exposed to the Weeping Angels in 'Blink' I thought it was a dumb, silly conceit."

"By the end of that episode I knew I would have nightmares for months."

~ codyish

"'Children of Earth' was amazing. There was so much complexity to it, and the way they solved it was downright horrifying."

"The 456 just felt so real with their motives, and were really dark compared to other Who-niverse villains."

"It wasn't that they were trying to build a galactic highway, or were trying to save the universe. Just that (SPOILERS) they were drug dealers/addicts and would kill millions if the didn't get their supply of children."

~ NinjaBreadManOO

Paranormal Activity

"Paranormal Activity."

"I was not prepared and only 12 years old."

"Traumatized for years!"

~ Sudden-Star-7190

Buffy the Vampire Slayer

"Buffy the Vampire Slayer episode 'Hush'."

~ Malk_McJorma

"The gentlemen were some of the best villains."

~ Sudden-Star-7190

Room 1408

"Room 1408 creeped me out."

"I usually don't find hauntings or ghosts scary, but this one was something else."

"Left me really uneasy when trying to sleep after."

"I had to keep a light on. I'm 46."

~ hartschale666

The Twilight Zone

"I find the The Twilight Zone episode titled 'Living Doll' to be particularly creepy."

~ Ill_Fisherman5547

"Talky Tina was so creepy."

~ peachesfordinner

"The Twilight Zone episode—'Mirror Image'—with the woman at the bus station who has a doppelganger still creeps the sh*t out of me."

~ BurningSlash88

Ghost Ship

"Opening scene from Ghost Ship."

~ teslatinkering

"This movie is 21 years old, I’ve only watched it once and I still remember this scene vividly."

"Props to the creators because I can’t say that about many movies."

~ PainfulPoo411

X-Files

"The X-Files."

"Episodes 'Home'—inbred family in Pennsylvania—and 'The Host'—the Flukeman."

~ True-Mousse4957

"I was going to say season 3, episode 12—'War of the Coprophages'."

"Only due to one little thing."

"Mulder is in a lab with some scientist looking at the weird cockroaches. They're just chatting away when a cockroach walks across 'your' TV screen."

"It's made to look like it's an actual cockroach walking across your in real life screen. We don't even have cockroaches like that in my region of the world, but it still freaked me out for a second."

~ STROKER_FOR_C64

The Blair Witch Project

"Not gonna lie."

"I saw The Blair Witch Project in the theatre after watching some MTV documentary on it the day before."

"I thought it was real and I was afraid to walk to my car."

~ heavymetalsculpture

Are You Afraid of the Dark

"There's an episode of Are You Afraid of the Dark—'The Tale of the Dead Man's Float'." 

"It's about a school that was built on an old cemetary and there is some sort of creature thing thant comes into the pool while some kids are swimming."

"I still think about that episode every so often."

~ streetsoulja31

"There’s that one episode—'The Tale of the Frozen Ghost'—where a kid froze to death at some point and the ghost kid just appears and says 'I’m cold' in such a weird inflection…."

"It still creeps me out now. And whenever I am cold, that’s the only way I can say it in my head."

"Man that series had no business being that scary!!"

~ mistresssweetjuice

For me, children in horror can always produce the creepiness factor.

Who doesn't feel unsettled after seeing the twins in The Shining?

So what movies or TV episodes creeped you out?
