History NightmareFuel / TeenWolf

* The death of [[spoiler: Void/Stiles]]: they scream in agony for a moment before their body petrifies, cracks, and crumbles into dust.

** And there's the flashback of Nogitsiune's first rampage, killing gaurds and prisoners alike. At first we see the aftermath of his initial rampage, filled with bodies ''everywhere'' and the scene where a group of people fleeing Nogitsiune through the halls. Eventually they run down the stiars to find a locked gate, with ''Nogitsiune still catching up to them''.

* [[spoiler: Void Stiles]] leading the Oni through the hospital in a murderous rampage in "The Divine Move"
* The death of [[spoiler: Void Stiles]]: they scream in agony for a moment before their body petrifies, cracks, and crumbles into dust.

* In-universe example: ''Devoid'' had big bad wolf Peter Hale freaking out right along with the rest as Stiles vomited up literally an entire person's worth of bandages.

** So much of this episode is disturbing mainly because, even without the supernatural elements, it still provides a pretty realistic demonstration of Japanese internment camps during WWII.

* Riddled starts out with Stiles held captive in a basement, with a bear trap on his leg and an inhuman, heavily wrapped up figure taunting him. Turns out it was just a dream, and he was ''only'' in the woods at risk of dying of exposure to the cold. Later, as he's having a brain scan, he has another vision in which the same figure, the [[BigBad Nogitsune]], forces him to answer a riddle, takes his bandages off to reveal he looks like Stiles underneath. A power surge happens at the hospital, and Stiles is seen leaving the hospital with an out of character look on his face. Ladies and gentlemen, Stiles [[DemonicPossession has left]] [[SplitPersonalityTakeover the building]].

** Generally the Oak Creek camp was a terrible place to live in. The lack of respect and proper supplies, the doctor selling much needed drugs to the black market, [[spoiler:the government covering up the cruelty and slaughter]]...

-->'''[[EvilSoundsDeep What has a neck]] [[OffWithHisHead but no head ?]]'''

* In "Echo House" the mental facility itself. It's dreary, depressing and very frightening -- and that's ''without'' it being a supernatural hotspot, which it apparently is also.

*** Scott's face says it all during this scene. Not only is he understandably horrified, he's completely speechless. He's downright ''terrified'' of his best friend.

** Adding to this, the following episode has Evil!Stiles pretending to be out of the fox's control, only to reveal himself to them once they're alone. He then proceeds to give a ReasonYouSuckSpeech to Scott while [[ColdBloodedTorture twisting a katana in Scott's abdomen.]] If not for [[BigDamnHeroes Dr. Deaton's intervention]], Stiles would have killed his best friend.

** [[spoiler: And, on the other hand, another fridge horror dose comes if those implications are true: Ethan and Aiden [[SelfMadeOrphan killed their own family]] to free themselfs from their abusers.]]

* The abuse [[spoiler: the Twins endured in their previous pack is kinda horrifing when one starts thinking about it. One, the abuse ranges from physical to emotional/psychological to even implied sexual. Its also implied they are born werewolves, so their families were more that likely part of their pack, which makes it even more horrifing, because their either stood and watched or even participated of the abuse]].

** [[spoiler: And special mention to one of them for responding to a NeckSnap by forcing its neck back into alignment, as if that was a mere annoyance.]]

* We see the creatures fight in the very next episode. [[spoiler: Indeed they are MalevolentMaskedMen, and seem to be after another Dark Spirit, and seem convinced it is Kira that they want. And they're [[ImplaceableMan not going to stop or let up until they have what they want.]]]]

** When the lights go out after Kira defeats Barrow, [[BlackCloaks several]] [[MalevolentMaskedMen figures]] materialize out of nowhere and attack Isaac. According to the promo for the season, there might not be people behind the masks.

* We're introduced to William Barrow in "Galvanize", a notorious mass murderer who blew up a bus full of teenagers because he claimed they had [[spoiler: glowing eyes]]. He's already creepy with that and his unhinged personality. But then he's admitted to surgery for what the doctors assume is a piece of shrapnel, and it turns out that it's really [[spoiler: a tumour full of LIVE FLIES]]. ''Holy shit''.

** And then there's his dream near the end of 3x13, he wakes up in a dream next to Lydia. [[spoiler: He sees ''something'' at the door. She starts begging him not to open it. Whatever it is has even Dream Lydia frightened. Just what is behind the door is left horrifyingly ambiguous.]]

* Stiles' hallucinations are pretty creepy to - he starts having nightmares and sleep paralysis, which is already disconcerting, but then he stops being able to read because you're not supposed to be able to read in dreams. Which means he never really knows if he's dreaming or not.

* 3x13, has Allison [[spoiler: having visons of Kate. She's alot scarrier then before.]]

** Another promo for 3b features someone staggering down a hallway, intercut with scenes of Lydia attempting to scream while unable to open her mouth, Allison petting a wolf's corpse with dead eyes, and a creepy apparition of the sheriff. The hallway opens into a blank white room with a sink and a mirror, revealing that the person is Stiles - and he's ''covered in blood.''

* The scene with Isaac's father. He initially comes across as okay if a little intense but when he asks about Isaac's grades, he see the fear flash across Isaac's face when he has to say he is failing a subject. Mr Lahey starts throwing plates around and telling Isaac to clean it up and then throws glass at his face and nearly blinds him, all the while never raising his voice above a soft sadistic tone that shows how much he enjoys terrorising his son. The look of absolute terror lets us know that this has been going on for a ''very'' long time. The worst part? There is nothing supernatural or mystical about it. Isaac's dad was just a vile sadistic monster who managed to be the most despicable and horrifying person on a show filled with supernatural creatures.
* The scene where Isaac's father is ripped apart and eaten by the Kanima. He completely deserved it and much more but it doesn't make the way he gradually realizes what a horrible situation he's found himself in any less chilling.

*** Just the fact that everyone else's hallucinations are enough to push them over the DespairEventHorizon, but Isaac is so used to being abused that he just lays there and accepts it.

* Whenever the full moon comes around, there's the subtle changes in Scott's behavior. He gets more aggressive, angrier, and at times his body language is downright predatory. It's unsettling to see that from a person who is otherwise a pretty NiceGuy.

* The sneak peeks for the season 3b include Stiles freaking out while a person tries to escape from a white screen and his classmates appear possessed. Playing in the background is a creepy child-like voice and the last lines we hear are Stiles saying "Wake up!" while the child sings "Life is but a dream"

Isaac's dad was just a vile sadistic monster who managed to be the most despicable and horrifying person on a show filled with all sorts of creatures. It's even worse when You realize that there are plenty of parents like that in the real world and some are even worse.
