1.First and foremost, the "evil furnace" scene in Home Alone — which was so scary because that moment was completely unexpected.
2.But the furnace scene was child's play compared to the "Large Marge" scene in Pee-wee's Big Adventure. Ooof, that was also completely unexpected.
3.Can't talk about things that were traumatizing without mentioning the drawings inside of the Scary Stories to Tell in the Dark books — *shudders just thinking about them.*
4.You know what else was also traumatizing? When Grandpa showed up as a zombie in Arnold's dream in Hey Arnold!
5.And basically everything about the "Haunted Train" episode of Hey Arnold!
6.The episode of Salute Your Shorts with Zeke the Plumber was a whole other level of freaky.
7.Also a whole other level of freaky were the episodes of Courage the Cowardly Dog where the fetus-like thing whispered, "You're not perfect"...
8....the mummy ghost that yelled, "Return the slab"...
9....and when the horrifying violin girl turned around.
10.The Boy Meets World Halloween episode was really, really messed up.
11.So was the Boogeyman transformation scene in the Disney Channel Original Movie Don't Look Under the Bed, which really went there.
12.I think we can all agree that the episode of Rugrats with Angelica's "brother" was nightmare-inducing.
13.And so was that episode where Tommy turned into an adult baby monster.
14.Speaking of things that gave us nightmares, nothing was more ominous sounding than the original Unsolved Mysteries theme song.
15.If the theme song didn't make you crap your pants, then the episodes about ghosts...
16....and alien abductions surely did.
17.Also, it wouldn't be fair to talk about Unsolved Mysteries without talking about the witness interviews that were very unsettling.
18.Anyway, the Unsolved theme song was a straight-up lullaby compared to the Are You Afraid of the Dark? theme song.
19.Especially with the shot of the swing moving in the breeze as if the ghost of a small child was on it (so creepy with the theme playing in the background).
20.AND THE CLOWN!!!
21.The clown in the credits was nothing compared to the episode with Zeebo the Clown...
22....the one with the Pool Monster...
23....and, of course, the episode with the Ghastly Grinner. LIKE HOW WERE WE SUPPOSED TO SLEEP AFTER THAT?!
24.Mr. Toilet Man from Look Who's Talking Too that gave millennials everywhere an irrational fear of going to the bathroom at night.
25.Matilda was basically a horror movie for kids. The scene where she gets placed in the Chokey was nightmare fuel.
26.And the scene where Miss Trunchbull is chasing after Matilda and Miss Honey gives me anxiety just thinking about it.
27.Of course, there is no movie that deserves the title Kids' Horror Movie more than Return to Oz. Like, the Wheelers were creepy AF.
28.And, of course, the scene where Dorothy steals the potion from the room with the heads.
29.Another scene straight out of a horror movie? The scene where the Grand High Witch reveals herself in The Witches.
30.Equally as scary was Judge Doom's reveal in Who Framed Roger Rabbit — especially when he did the high squeal voice.
31.Speaking of high squeal voices, the guy with the prosthetic chin who appeared in the Perfection commercial sounded and looked so sinister.
32.The intro to The X-Files was just eerie AF (and I still get a chill up my spine when I hear it).
33.We don't talk enough about how scary the Goosebumps TV show theme song was, but even scarier than the song was the part during the opening when the dog's eyes turned yellow.
34.Of course, we can't mention Goosebumps without mentioning its most frightening character: Slappy the dummy.
35.And lastly, the most disturbing thing ever, when your Furby would start talking to itself unprovoked at like 3:00 a.m. (EVIL!)
