WARNING: Spoilers are unmarked.
- The pure Adult Fear in Mary's voice when she realizes it's not John in her baby's nursery.Mary: "SAMMY!"
- The Woman in White attacking Sam. We get a glimpse of her real face, and it is HORRIFYING.
- Jessica's blank, bloody stare when she burns on the ceiling.
1x02 - Wendigo
- The titular Monster of the Week attacks in the dead of night in the middle of an isolated part of the woods. Oh, and it can unlock doors and get inside your house. And you never see it from the front standing in the light; you only see the the characters' reactions to it when it appears. Good luck and sweet dreams if you live in Wendigo territory.
- The old man who managed to survive a Wendigo attack as a boy and was not only left with scars but, like several victims of beasties in this series, had to "forget" that it was a monster and lie to himself that it was a bear attack.
- The worst part is that the wendigo Was Once a Man. And it can think.
1x03 - Dead in the Water
- The ghost of Peter Sweeney dragging his victims down into the dark water is terrifying enough, but the idea that he can get at you from any source of water; a bathtub, a kitchen sink... ::shudder:: And a reminder that this was just a child ghost, one with a very strong grudge. The idea that a child is that angry, to slowly kill all your loved ones, so that you feel despair, just before he comes after you...
1x04 - Phantom Traveler
- The very idea of Demonic Possession is Nightmare Fuel. You might be a little scared or nervous about something important or scary to you, and then a monster from Hell takes your body for a joy-ride and will do whatever it wants with it, and the odds are vastly against you ever being released even if you die while it's riding you.
1x05 - Bloody Mary
1x06 - Skin
- Shifter!Dean tearing his skin off. The worst part may well be when he pulls out his own teeth. "Hey Man Nice Shot" just makes it all the more effective.
- Shifter!Dean chasing Becky through the house and eventually tying her up, with the implication that he was going to rape her.
1x07 - Hook Man
- "Aren't you glad you didn't turn on the lights?"
1x08 - Bugs
- Bugs in the shower. Bugs all around you if you fall into a pit by accident. Bugs crawling in your ears, in your eyes, swarms of bugs... And then the skies fill with them and your only option is to hide and try to last the night.
1x09 - Home
- The dreaded Cymbal-Banging Monkey clanging as the poor repairman's arm gets caught in the garbage disposal unit.
- The poltergeist trapping the young boy in the fridge. Adult Fear to the max.
1x10 - Asylum
- One scene features a few seconds of a random ex-patient twitching writhing violently in a straitjacket. Sam and Dean finish talking about something and walk away, camera pans out, and then it's like something straight out of Silent Hill.
- The moment where the evil psychiatrist comes out and attacks Sam.Don't be afraid. I'm going to make you all better.
- The Girl of the Week being trapped in a locked room with an terrifying ghost. A lesser person would have gone into hysterics.
1x11 - Scarecrow
- The Monster of the Week is terrifying enough; a pagan god that hunts you through the forest, takes you, skins you, and wears you for a year until its next victims come along. But even worse is the seemingly friendly townspeople that will give you a free meal, fix your car, and send you into the forest to become food for their god.
1x12 - Faith
- The Reaper's creepy smile as it rips the very life-force from its victims is horrifying. Then there is its terrified victims running for their lives away from this monster that nobody else seems to see.
1x13 - Route 666
- Cyrus Dorian's water-logged corpse falling from his truck in a sudden jump-shot is as quick as it is startling.
1x14 - Nightmare
- Max is shown killing his step-mom, in Sam's vision, by telekinetically plunging a knife into her eye. Perhaps the most disturbing part is what he says before it happens:Mrs. Miller: Max, I'm sorry!Max: No, you're not. You just don't want to die.
1x15 - The Benders
- There's a lot of creepy Eye Scream in this show. In this episode, Dean gets tied down and interrogated by the titular family who threaten to burn his eye out with a hot poker. Then Pa Bender tells pint-sized Missy to keep watch on Dean...which she does by holding the point of a knife about half an inch from his eyeball. If you listen carefully, you can hear Dean's voice break as they torture him.
- The sheer terror that the Victim of the Week goes through as the Benders hunt him through the forest, laughing at his fear and stumbling attempts to escape or fight back, ending in them putting him down like a wounded animal. Plus, all the junked cars and pictures on their trophy wall indicate they've been doing this a long time...
- Everything in the house seems to demonstrate that the Benders are COMPLETELY INSANE. The bones hung up on the ceiling, the jar full of human teeth, the pictures the Benders took with their dead victims. We hear Pa Bender doing...something in the kitchen. We never see exactly what it is he's doing, but the sounds alone are terrifying enough to keep you up at night.
1x16 - Shadow
- The Daevas are some of the most terrifying things ever featured on the show. They have no physical body, they are the shadows and they will tear you to shreds while you are completely unable to fight back. After all, how do you fight a shadow?
1x17 - Hell House
- Mordechai Murdoch is scary, but the real Nightmare Fuel here is the idea of a Tulpa. How many monsters exist in the Supernatural world just because somewhere, somebody believed in them enough?
1x18 - Something Wicked
- The image of the Shtriga sprawled over little children, drinking their souls as they lie there, helpless, is terrifying. Even worse is the knowledge that she has done this before, and nobody managed to stop her there. She claimed what looked like 10-20 children and, according to Sam who saw the records of the towns she last victimized: "[She was] just getting started."
1x19 - Provenance
- Melanie Merchant killing her parents and siblings in their beds with a straight razor is scary. But the noise she makes when she finds Sam and what her face does? Sheer Nightmare Fuel.
1x20 - Dead Man's Blood
- Vampires. One day, you are out for a drive with your sweetheart and you see a man passed out on the side of the road, so you stop to help. Next thing you know, you're in an abandoned building, being ripped to shreds by a pack of hungry monsters while your girlfriend is being turned into one of them.
- What they do to that poor girl is probably one of the darkest things that has ever happened in the whole series.
- Also their eyes in the lights of the truck as John pulls up to the confrontation with the nest.
1x22 - Devil's Trap
- It might be Fanservice for some, Fan Disservice for others, but the scene where Dean is bleeding to death (HIS ORGANS ARE MAKING SQUELCHING NOISES) is made even worse by the "Daddy, please..." with him crying and the blood running freely from his mouth and Azazel letting John come back up to make him watch...
- Tessa's true form looks like a cross between a ghost and a corpse that's been underground for a hundred years.
2x02 - Everybody Loves a Clown
- The Monster Clown and how he takes his victims; their children let him in. Because after all, Everybody Loves a Clown.
- When the Rakshasa reveals himself in his human identity, he removes his sunglasses to reveal creepy white eyes and his smile literally stretches ear-to-ear right before he goes invisible and starts attacking. It's a really good thing he isn't wearing his clown outfit at the time or it'd be so much worse.
2x03 - Bloodlust
- A female vampire is decapitated in the beginning. Gordon nearly gets decapitated by a vampire but Dean shows up in time to decapitate the vampire instead. And then there's when Eli bares his teeth and gets menacingly close to Sam or when he and another guy assault Sam in his motel room.
2x04 - Children Shouldn't Play With Dead Things
- The Pet Sematary vibe that Angela gives off makes her creepy, but her sudden switches from serene calm to murderous rage are terrifying, especially when she goes after a victim.
2x05 - Simon Said
- Dean being roofied into putting the gun to his head. Finding out about his suicide/death-seeking nature just makes it a hundred times worse.
- Webber and the terrified, mind raped Tracey, when he's making her undress herself in the car so that he can rape her before he makes her jump off the bridge:Webber: I want you to listen to me very carefully, okay? When we're done here, I want you to head over to the edge of that dam, okay?Tracey: Okay.Webber: And when you get there, you're gonna think you can fly. And you're just gonna step right off. [strokes her face] You can fly, can't you?Tracey: [starts sobbing again] I-I think so.
2x06 - No Exit
- The sheer terror that Holmes' victims must have felt, locked in those iron coffins as he whispers to them and strokes them, lingering and exclaiming how soft they are. Dean pulling out a bloody hank of hair and scalp makes it even worse, how did Holmes actually kill and dispose of them?
2x07 - The Usual Suspects
- The ghost with the slit throat trying to talk.
2x08 - Crossroad Blues
- Knowing what one goes through near the end of their time as seen in this episode (and later personally by Dean in "No Rest for the Wicked"). If it wasn't bad enough that you'll always be seeing the faces of everyone you see suddenly take on the appearance of rotting corpses as a reminder that your time is almost up, you also have to eventually face those damn hellhounds...
2x09 - Croatoan
- The calmness, bordering on creepy serenity, that the Croats show, right before they start screaming and coming at you with the first sharp thing they can find. And what it must have been like for those few sane people as their friends and neighbours turned on them;Duane Tanner: I...I saw Roger McGill being dragged out of his house by people we know! They started cutting him with knives!
2x10 - Hunted
- Once again, Gordon manages to be completely terrifying without ever raising his voice or loosing his cool. The scene where he tells Dean how he tortured a demon that was possessing a young girl for information stands out.Dean: What happened to the girl it was possessing?Gordon: She didn't make it.
2x11 - Playthings
- The sight of the man who fell down the stairs; head turned completely around, arms still outreached trying to catch himself, mouth gaping open like he's screaming but nothing but blood coming out. It's enough to give anyone nightmares.
2x13 - Houses of the Holy
- It has to be said, this show has a disturbing ability to make near-rape scenes a thousand times scarier, like this episode with the man about to rape the woman ("I'm sorry! I'm sorry, it's just I've never done this before.")
- The other two victims were disturbing as well. The first one who kidnapped two college students and buried them under his basement, dead or alive we don't know, and the second who was grooming a thirteen-year-old girl over the Internet. If "the Angel" hadn't stopped them
2x14 - Born Under A Bad Sign
- The near-rape scene. Maybe it's because we don't know Sam is possessed at this point, maybe it's because it's one of the leads doing the near-raping, maybe it's the size difference, maybe it's because Jared Padalecki is scarily good at being menacing and Alona Tal was fantastic at acting terrified... There's a subtle but very noticeable contrast to how he normally acts; the way he hunches just a little and is generally the nonthreatening of the duo, and all of a sudden his body language is a bit more aggressive and his smile just a little too gleeful, almost a Slasher Smile compared to his usual quick, wide, and innocent one. The scare comes at least in part from the fact that you are aware that the 6'4" Sam could easily take down the petite, untrained Jo with no real effort just before he proceeds to do so. Plus, demons have superhuman strength, right? In "Phantom Traveler," one even opens a door with two tons of pressure on it. So if they had sex with a human, especially non-consensual sex, it could result in a painful case of Death by Sex if they weren't holding back. Poor Jo really dodged a bullet here.
2x16 - Roadkill
- The ghost of Jonah Greely, who Dean describes as "[looking] like he lost a fight with a lawnmower."
2x17 - Heart
- Madison's eyes when she turns are pure beast, not a single trace of anything human left in them.
- The idea of being a werewolf is scary as hell. You may not even realize you are one, even as you continue finding the bodies of those people you either like or dislike that you have killed at night and don't even remember dead around you, until one day a hunter comes to put you out of your misery.
2x20 - What Is And What Should Never Be
- Djinns have been tricking people into staying in their own heads, happy for "years," whilst outside they're slowly dying. On the other hand, imagine if Dean's dream was real; what if Sam had had to watch his brother kill himself, raving on about monsters and how the whole world is a dream?
- The idea that the Seven can get you to act on things you are capable of doing, but don't because of common sense and survival instinct. The woman who killed, just to get the shoes, something we are all capable of, but don't do, because of common sense.
- The part where a hunter was brainwashed to down a jug of drain cleaner while the titular seven demons roared with laughter and his wife hysterically pleaded him to stop was possibly the most disturbing scene in the whole series. It's the "poetic justice" bit that makes it even more disturbing, because you can't help but understand why the demons would love it so much — it's rather like how Bobby got Possessed!Sam to drink beer with holy water in it.
- The bodies of the people touched by Sloth...just sort of withered, with the veins visible.
- Another moment that's a throw-away line by Bobby who says that two of the Seven Sins' victims will survive, but they have a life-time of therapy ahead of them. 99% of the time a demon's meat suit dies as a result of the possession, and you'd think that the few who survive would be the lucky ones, but they aren't. Their lives have been forever altered by their experience, they will be traumatized and might actually break down from the guilt of their actions while possessed or the fear that it will happen again. Nobody comes out of demonic possession the same, either they die or they are changed for life. To be specific, the two surviving victims are (respectively) the one who forced the family to sit on their couch until they starved to death and the one who expressed a desire to sexually assault Tamara. Vessels are often aware to some degree of what their bodies are being used for. The Sloth vessel may have realized that the family was going to die when he left them, and the Lust vessel may have heard her own voice saying what the demon wanted to do to Tamara.
3x02 - The Kids All Alright
- Not the Monster of the Week, but the image of a mother, with complete, cold calmness, driving to a lake with her daughter, getting out of the car, locking the doors, and then releasing the emergency brake. Finding out what the kid really was made it less scary.
- The first time the Monster of the Week is revealed the rear view mirror (pictured above). Combine the Creepy Child with that little flash and ugh.
- Even without the monster faces, the Monster of the Week were creepy even when standing there and doing nothing. Their dead expressions, similarly child-like tone of voices, and their sudden outbursts of white-hot rage when separated from their victims.
3x03 - Bad Day at Black Rock
- The gruesome fate of Wayne once he loses the Rabbit's Foot. Gory Discretion Shot helps, but not as much as you'd think.
3x05 - Bedtime Stories
- Anyone who fit the fairy-tales had to act them out. The old woman was the worst part.
- The worst might actually be the "Big Bad Wolf". This innocent guy was forced to murder multiple people because he had a tattoo of something a little girl mistook for a wolf. Unless he ran, he probably went to jail for what Callie forced him to do.
- If they hadn't stopped her when they did, Dean would have slashed that poor guy's stomach open, not realizing that he's being controlled, or at least influenced to play out that series of events.
- Though there are thankfully no casualties with "Cinderella", the poor girl had her stepmother suddenly flip out and abuse her. Assuming that her stepmother isn't normally of the wicked kind, she's likely going to be horrified when she learns what she did to her stepdaughter.
3x08 - A Very Supernatural Christmas
- Sam's fingernail being pulled out.
- The dungeon under the Monster of the Week's house, the filthy tools on the walls, and the blood covered sack that starts screaming when Sam and Dean touch it.
- Whoever was in that sack was alive, but not yet in too bad condition to be merely groaning in pain. He hadn't been finished off yet, or brought to a state of near death, so he was likely in there in fear, waiting in pain and fear, to escape.
3x09 - Malleus Maleficarum
- The opening sequence involving a woman's teeth falling out of her mouth.
- Whenever witches use maggots. Especially that scene with the hamburger.
- The first witch's arms being slashed open vertically and deep.
3x10 - Dream A Little Dream Of Me
- Bobby's nightmare about being chased through his old house with his wife, covered in blood and screaming at him the entire time, the house shaking as she bangs on the door to get at him.
- Dean's Doppelgänger, especially after Dean supposedly kills him. He gives Dean the Black Eyes of Evil and...Demon!Dean: You can't escape me, Dean. You're gonna die. And this...this is what you're gonna become!
3x11 - Mystery Spot
- All of Dean's deaths. It's played for laughs, but the ways Sam tries to save him, only to have it blow up in his face, and kill Dean in some other way. For months on end.
- Sam, after Dean's temporary-real death. Completely emotionless, driven, almost robotic. Impressively precise in a sociopathic way (it's mentioned he took out a ton of demons and a vampire nest in the intervening time), but it's still disturbing the way he patches himself up without a sign of emotion.
- Even worse was when Sam "killed Bobby". Sure it turned out to be the Trickster, but Sam did that on a hunch that it wasn't really the man who had become his adoptive father. What if he had been wrong
- Let's not forget the subtle suggestion how his grip on reality was slipping. At one point in the montage, he's in a hotel room eating and across the table is a plate with a bacon cheeseburger and fries (Dean's favorite).
3x12 - Jus In Bello
- Lilith is total Nightmare Fuel. Not only is she possessing a little girl, younger than 11 from the look of it, she annihilates the police station and kills everybody that Sam and Dean saved. Horrible, and then it got even worse in Season 4...
3x13 - Ghostfacers
- Freeman Daggett appearing in the camera with glowing eyes is a hell of a Jump Scare.
- Poor Corbett's fate. His terror as Daggett has him tied up in his basement with corpses dressed in party hats and ancient rotting birthday food. Then Daggett killing him while whispering: "It's OK."
3x14 - Long-Distance Call
- This entire episode is Nightmare Fuel. First the Monster of the Week sucks people's souls out, has a maw full of needle teeth, and unhinges his jaw like a snake to feed. Then it goes into a speech about how it used to barely be able to feed itself because back then people looked out for each other, "they had community" and because people were more willing to accept strange things back then. Now, all he has to do to feed is pick up the phone. "You've never been so connected. And you've never been so alone." Chilling, and even worse when you realize that in a way he is actually right.
- The scene in Lacey's bedroom. Her "mother" talking to her through the computer, ending by saying: "I'm right here with you." The screen goes dark and through the reflection we see a woman appear and reach out for Lacey, and after she rips the computer's power cord out it turns back on and starts endlessly typing "Come to Me" over and over and over again. Perfectly understandable if you don't like watching that scene in the dark.
- The Crocotta manipulating that poor fireman into nearly killing Dean by pretending to be his daughter, and Dean into nearly killing an innocent man by pretending to be John. How easy it was makes it even worse.
3x15 - Time Is On My Side
- What about almost the entirety of this episode? You've got a guy's guts literally spilling out, another guy being shown his still beating heart and Sam's puppy dog eyes nearly being gouged out with an ice cream scooper!
- How the boys deal with Doc Benton is terrifying, burying him alive. He'll be down there until his body parts rot and he falls apart, maybe even longer then that. Maybe until there's nothing but dust left.
- The final moments when Bela realizes just how screwed she is. The smug overconfidence has completely disappeared and she becomes like a scared little girl. It gets even worse when the clock reaches midnight and we hear the horrible howls of the hellhounds and all Bela can do is look out the window, knowing that she cannot escape.
3x16 - No Rest for the Wicked
- The very end of the episode with Dean chained up in Hell with hooks in his side and shoulder. Even worse when you read the Word of God regarding this scene and learn that that particular place is "the waiting room." Meaning it got worse than that, far worse.
- Worser and worser, Dean being torn apart by hellhounds. Lilith's child-like laughter, mixed with Dean's pain-wracked screams, throughout that entire scene makes it even more horrific.
- Little Girl Lilith. Despite the complete horror of a cute kid killing her pet and her grandfather (after killing her grandmother) juxtaposed with her wanting to be pushed on the swings or having birthday cake every day, what about when the little girl's NOT possessed anymore? Not enough therapy IN THE WORLD to get over what she went through.
- The flashes of Hell that Dean keeps experiencing. They only last a second but each one shows his bloodshot and terrified eyes in a blood-red light, as around him there is what sounds like the screaming of a million people at once.
- The aftermath of the diner when the Angels are done with it. True they were Demons, but seeing them with their eyes burned out of their sockets and the one survivor nearly incoherent with fear, you know that whoever did this does not mess around.
4x02 - Are You There God? It's Me, Dean Winchester
- The unexplained Noodle Incident between Bobby and the two little girl witnesses:Girl One: You walked right past that door.
Girl Two: The monster had us. And you didn't find us.
- The return of Henriksen, and learning that when Lilith killed him and the rest of the survivors in "Jus in Bello" it took 45 minutes...
- Meg revealing that after she died as a result of Sam and Dean exorcising her, and not recognizing that she was possessed in time, her little sister committed suicide after seeing her older sister's broken body in the morgue. Reminds you that not only the meat suits have their lives ruined by demons, their loved ones do too.
4x04 - Metamorphosis
- Jack after transforming into a Rugaru, his lined face, red eyes and sharp teeth. And the horror that he turns Travis into.
- Travis trying to burn Jack and his pregnant wife Michelle alive. Horrifying on its own, but when you take into account that Travis is a hunter it's even worse, he is meant to be a good guy and yet what he tries to do here is worse than anything even Gordon Walker ever did. A reminder that Hunters are not always the good guys.
4x06 - Yellow Fever
- Lilith in Dean's hallucination revealing that every month in hell is actually 10 years. The terror in Dean's eyes as he realizes who has just grabbed onto him is another truly scary moment, even Azazel didn't scare him that much. She also asks Dean if he does remember what happened in Hell. The thing is, though he's terrified, he doesn't seem to be scared of the horrible memories, or at least doesn't remember fully, meaning that whatever happened down there was so bad that Dean blocked it from his memories.
4x07 - It's the Great Pumpkin, Sam Winchester
- The razor blades in the candy in the opening scene.
- A few minutes later in the same episode, the potential Halloween Shout-Out with Jenny getting her face boiled in the now-scalding apple tub.
- Only for a moment, but the creepy mask in the art room that seems to be designed with blood coming out of its eyes and mouth.
- The stoner getting dragged into an open coffin when Samhain locks them in with the newly arisen zombies, and the sudden explosion of blood that comes out of the coffin a few seconds later.
4x09 - I Know What You Did Last Summer
- Anna crying "Her face!" while looking at Ruby sends the imagination into overdrive. The results can be nightmare-inducing.
4x11 - Family Remains
- The brothers believe a family who just moved into a new house is being haunted by a ghost. Turns out the "ghost" is a human girl who lives in the walls. Most episodes, you can calm yourself down by reminding yourself that monsters aren't real, but not this time...
- The screams that both the Girl and Boy in the Wall make when they attack really stick in the mind after the episode.
- In that same episode, when it's revealed what happened to Buster the dog. Heck, the savage smile on their faces as they tore a live rat apart with their teeth.
4x13 - After School Special
- The boy jamming the Jerk Jock's fist down a food processor.
4x14 - Sex and Violence
- The sex scene with the siren. It's a beautiful naked woman until you see its reflection as a lumpy, hairless, gray-skinned thing with a snake-like nose and a rotted mouth. Imagine having sex with that.
- Hell, imagine being put under its spell and tricked into murdering your loved ones, before it leaves you behind to spend the rest of your life in prison with the realization of what you've done.
4x16 - On The Head Of A Pin
- Every scene of Dean torturing Alastair. Especially the utterly dead look that Dean has throughout the entire episode, he's clearly letting out a part of himself that he would rather didn't exist, and suppressing the better parts of him just to be able to get through it without breaking down.
- One of the worst moments came when Dean forced the salt down Alastair's throat. Considering that eating ten or so table spoons of salt could kill you within an hour.
- When Alastair gets loose, Dean goes completely limp the instant Alastair gets a hand on him. He's not even trying to resist. Thirty years' worth of conditioning, huh?
4x17 - It's A Terrible Life
- The guy microwaving his head to commit suicide.
4x19 - Jump the Shark
- The ghouls slicing Sam up while eating him alive. Gross, and Squick.
- How each Winchester discovers that Adam has been Dead All Along. Dean finds his corpse Gutted Like a Fish, while a captured Sam learns he had been Eaten Alive by Ghouls wanting revenge on John Winchester. Can double as a Tear Jerker when you remember Sam saying it's In the Blood.
4x21 - When the Levee Breaks
- Sam's detox telekinetically slamming him across the room, and when every vein in his face turns black with demon blood in his reflection.
4x22 - Lucifer Rising
- Azazel's slaughter of the nuns in the cold open.
- Castiel. While not outright terrifying, the Broken Angel-ness starts bad (normally straitlaced Cas organizing hippie love-fests?) and just gets worse (normally straitlaced Cas turned organiser of hippie love-fests... Who is entirely unruffled, telling past-Dean about how he's effectively human and takes amphetamines as "a perfect complement to that absinthe," while on the way to what he knows is his death?) Unsettling, even by Supernatural's standards:Dean: Are you...stoned?
Cas: Generally, yeah.
- There is something deeply unsettling about Lucifer when he's walking about wearing Sam. It hits the Uncanny Valley in so many ways.
5x06 - I Believe the Children Are Our Future
- The idea that someone could die just cause you tell the wrong kid Lies to Children is both this and Paranoia Fuel.
5x11 - Sam, Interrupted
- The wraith hallucinations, where Dean sees everyone's reflections as rotting faces. Then there's the sketch of the wraith in Martin's journal — thanks for that, Martin! Then there's its M.O. of driving people insane so that it can feed off of them and, once it's used up a victim, it kills them in a way that makes it look like the patients simply killed themselves. Who knows how many mental institution patient "suicides" were actually the work of a wraith that was never caught?
5x13 - The Song Remains The Same
- Michael killing Anna is...not a pretty sight. Hint: it is not just as simple as impaling her with an angel blade. It is probably the most excruciating death of an angel in the whole series.
5x14 - My Bloody Valentine
- That couple at the beginning was nightmare fuel in its pure, distilled form; none of the Horsemen are family friendly, but Famine is a very special case. According to an interview even Ben Edlund, the writer, was disgusted.
- The scene at the end where the guy is lying dead in the deep-fryer. His whole upper body was in there. The implication being that, since he was earlier shown sticking his hands in the fryer to get to the food within, once he either ate his deep-fried hands or lost use of them, he stuck his face in to eat more.
- Watching Sam slowly falling apart over the episode as Famine's influence makes itself known and his addiction to demon blood starts coming back to haunt him can be particularly unsettling. Especially when the two demons show up to capture him and he completely loses control.
5x19 - Hammer of the Gods
- A collection of the most powerful pagan gods are so terrified of Lucifer that they meet together to create a plan to stop him. This includes Odin, Kali, Baldur, and Mercury (the Roman form of Hermes). What happens when he shows up to the gathering? A one sided slaughter the likes of which is rarely seen in Supernatural.
5x21 - Two Minutes to Midnight
- Death. When first we hear of the Four Horsemen, it's assumed that they're demons. This is very much so not the case when it comes to Death. The guy scares the ever-living crap out of Dean Winchester, who takes crap from NO MAN. Then there is his introduction. As "O Death" plays, a nearly skeletal man steps out of a car and quietly walks down the sidewalk. Someone bumps into him and blames him for it. Without a word, the man brushes off his shoulder...and a second later, the guy who bumped into him drops dead. This is Death.
- Sam acts a little bit off during most of the episode.
- Dean's nightmare about Azazel coming back for Lisa and Ben.
6x02 - Two and a Half Men
- A shifter poses as women's husbands while the husband is out of town, has sex with them, and comes back for the baby nine months later. This has resulted in divorces in some cases. And he is perfectly willing to kill the woman and her husband to get the kid back.
6x03 - The Third Man
- The effects of the Staff of Moses on the dirty cops — turning into sacks of blood, filled with boils and locusts eating out their brains. Castiel torturing the kid — aptly named Aaron — to check his soul could also qualify.
6x06 - You Can't Handle The Truth
- Sam's increasingly cold behavior. In one occasion, when interrogating the sister of one of the victims, Sam shows a total lack of empathy and appears to get a kick out of it when the sister breaks down in tears and confesses to lying. The deaths also count (the first one being a girl asking for the truth, but it Went Horribly Right and she killed herself and the second one being a Dirty Old Man drilled to death by the truth-cursed dentist in a fit of rage after confessing to having sex with said dentist's daughter Melissa while she was at his house for his own daughter's sleepover, knowing he wouldn't get caught, and he didn't. Said dentist later committed suicide himself.)
6x13 - Unforgiven
- Arachne's disfigured face. You can't tell if Arachne come that way or if they were from burns. And don't even get me started on the eyes. And since Arachne apparently breed, what did Roy mean when he told Sam he was considering turning him?
6x14 - Mannequin 3: The Reckoning
- The episode had possessed Murderous Mannequins stalking people then killing them. The worst part was when they moved on-screen. At least one of the wikis for Supernatural changed its first recap picture for its page on the episode (that of a mannequin smiling after killing someone) because it was a little too unsettling for some people.
6x16 - ...And Then There Were None
- The hissing parasitic "Khan worm" that crawls into your ear and makes you kill people. At least you can see 30-foot monsters; this thing can hide and strike from anywhere. Plus, it looks nasty.
- Castiel's vessel melting and the scene where he unbuttoned his shirt to reveal Purgatory souls are clawing at him from the inside, trying to get out. Becomes even worse if you allow yourself to think of how many of said souls have encountered and been killed by the Winchesters, how many of them see the Winchesters and want revenge...
- The episode introduces the Leviathans, who spread out into the water supply, infecting anyone who comes in contact with it. Think twice before you take that next drink from a water fountain
- Not only that, but the fact that anyone could be one of them, and you wouldn't know until it's too late. And then there's those mouths
- The Leviathans' Slasher Smile and maniac glee. On the other hand, it's a Moment of Awesome for Misha as an actor.
7x03 - The Girl Next Door
- The ending. The Leviathan taunts its victim and says: "Plain old people taste fine, but everything is better with cheese", then upends a pot of melted cheese onto his head and, while the victim screams, reveals his Leviathan face right to the camera as he moves in to eat the dying victim. Repulsive.
7x09 - How to Win Friends and Influence Monsters
- Bibbing. A Leviathan that has pissed off their boss enough gets a bib put on them and is then forced to eat himself. It has got to be one of, if not the, worst ways to die the series has depicted, even if it can only happen to the bad guys. From Bad to Worse: Leviathans are nigh invulnerable and regenerate when injured. Now think about that. You'd be trying to eat yourself faster than you can heal and, if you were too slow, would have to do it again.
7x16 - Out With The Old
- The cursed teapot causes a woman to pick up a super-heated metal teapot with her bare hands, then pour the super-heated water into her own mouth. What makes it worse is that you can see her horrified expression as she pours.
7x17 - The Born-Again Identity
- Sam's hallucinations of Lucifer and the Cage. You'd think the meat hooks, chains, and constantly being told that nothing around you is real would be bad enough. No, the visions have to get so bad that Sam is incapable of sleeping, has to be institutionalized (however briefly), and comes close to dying of sleep deprivation. It also veers into Fridge Horror territory when Lucifer does things like call Sam "bunk buddy." It makes you wonder what exactly happened down there.
7x19 - Of Grave Importance
7x21 - Reading Is Fundamental
- The scene where the Leviathans effortlessly kill angels in a truly horrific way.
7x22 - There Will Be Blood
- The Leviathans' plan. Unlike other evil plans in the show, that tend to focus only on supernatural aspects, Dick Roman is manipulating numerous parts of everyday life. He's taking control of the media, food companies, and more. Why? So he can manipulate everyone on the planet into becoming stupid, complacent, overweight sources of food for the Leviathans, and set up slaughterhouses so every human in the world can be used to make a massive meal for the Leviathans. Oh, and he's doing it in ways most people aren't even aware of until it is too late. Once you bite any of the tainted food he's put out there, it is so addictive, it is probably too late for you. But at least you'll become so stupid you probably won't care you're being eaten. To make it worse, Dick is putting chemicals to change people in every food with high fructose corn syrup, so almost every piece of food you can buy will turn you eventually into a Leviathan's meal. The scariest part of all this is that they consider humans (over 6 billion of us) to be a limited resource.
- Most of Crowley's actions. Torturing Samandriel, blowing up one of the future prophets leaving Kevin covered in their blood, and cutting Kevin's finger off. Keep in mind, one of those future prophets covered in Ludicrous Gibs is a little kid. This episode proves that while Crowley may be affable, he is most definitely EVIL.
- Castiel's situation regarding Naomi's "little chats." Not only is he being forced to spy on the Winchesters against his will (literally, he's compelled to answer Naomi's questions while in her office), but he doesn't even remember doing it.
8x10 - Torn and Frayed
- The scene where Castiel flashes back to a time when Naomi strapped him to a chair and seemingly lobotomizing him.
- Chuck's fate, according to Castiel. He is dead and we don't know why or how. It's horrifying when you think what Crowley did to the OTHER prophets, including Kevin. Did Crowley torture Chuck to death? Did he just kill him? Chuck was portrayed as weak and frightened in most of his appearances. Less horrifying when you find out The Reveal in Season 11 that Chuck is not a prophet, but actually GOD! One wonders if Crowley even tried to confront Chuck and what happened when / if he did. Hilarity Ensues when King of Hell tries to torture God?
- Actually, it's likely that Chuck's "death" was actually him going Somewhere at the end of "Swan Song." He isn't actually dead, he just left. Plus, since Cas didn't know Chuck was God, it's easy to see why he'd think Chuck died
- In the Bible, prophets ascend straight to Heaven when their work is done, without dying. Some of them become angels (Metatron used to be a human prophet according to most angel lore) but they do just vanish.
8x11 - LARP and the Real Girl
- The Monster of the Week. The way it just pops out of nowhere provides a genuinely terrifying Jump Scare, and the deer-skull it uses makes the head seem unnaturally long. Of course this gets a little less ruined when it's revealed to be a fairy, in the form of Gilda who Charlie has a teeny bit of a crush on.
8x17 - Goodbye Stranger
- The opening, in which Naomi has apparently been forcing Castiel to kill copies of Dean over and over again as a conditioning strategy. It's bad enough that the first thing the viewer sees when the episode begins is Castiel dispassionately killing a pleading Dean, but when the camera pans up to reveal a room filled with a huge number of Dean-corpses, the situation becomes even more disturbing.
8x19 - Taxi Driver
- When Hell is re-revealed. It's no longer just a abyss of smoke and chains, it's a literal torture dungeon where you're tormented by demons taking the form of people you loved. One woman was so broken by it she kept saying "You came, I prayed for it, you came, I prayed for it" to Sam. All with the sound of souls being eternally tortured. Actually, the re-introduction is even worse than that, when you remember that Crowley previously mentioned that after taking over, he changed Hell into an endless corridor where people are forced to queue for all eternity. Now it's looking worse than ever before, cruel and twisted just like Crowley himself has become.
8x21 - The Great Escapist
- What Naomi and her angels do to the Biggerson's diner that Castiel arrives in. Everyone is massacred except for the waitress, who is sitting on the ground with her back against the counter and HER EYES BURNED OUT AND BLACKENED and whimpering over and over in a pleading voice: "You need to stop. Please. You need to stop." Not to mention the moments leading up to it. Castiel is rapidly flitting through various Biggerson's diners around the world, all with the sound of people laughing and having fun. Then the sound just stops. He looks down to a table covered with blood, then turns to see the entire restaurant he was in just minutes before, completely massacred.
8x23 - Sacrifice
- Crowley's Evil Plan. Actually, Crowley in general is nightmarish in the whole Season 8. Previously, he walked a fine line as Affably Evil, but now he no longer has any need to broker fragile alliances built on mutually assured destruction with the boys against Lucifer or the Leviathans: He's the last Big Bad on the playing field, and he has no reason to hold back. Need an example? Check out the climax of the season, where Crowley intends to systematically slaughter everyone that Sam and Dean ever saved, in order, to get what he wants. This Evil looks a lot less Affable now.
- Hael goes from being a cute, quirky angel who built the Grand Canyon herself to a fucking monster. Seeing her seething, covered in blood and glass, ranting about how she'll "make Lucifer's fate look like child's play" is horrifying.
9x02 - Devil May Care
- Abaddon in her very first episode of Season 9 has proved she is Nightmare Fuel. She wants war with humanity, for Demons to rule the earth, and is prepared to string up hunters just to get Dean's phone number, and unlike other Demon leaders like Lilith and Crowley she's willing to get with the times and equip her soldiers with assault rifles and wear kevlar body armour herself. Demons with assault rifles. That alone qualifies as Nightmare Fuel. And even worse is what she wants from Dean, Abaddon wants Dean as her new meatsuit, Squick factor of a girl being inside Dean's body added onto what she plans to do if she gets her hands on him:Abaddon: Oh. Well You know I've loved this body since the moment I first saw it. You're the perfect vessel, Dean, you give a girl all sorts of nasty ideas. So go ahead and play hard to get, and I'll peel off this no demons allowed tattoo, and blow smoke up your ass.Dean: Oooh, well I gotta tell you between you and me, it is a horror show up there.Abaddon: It can get worse, trust me because once I'm on top I'll make you watch. And I'll use your body. Have you ever felt an infant's blood drip down your chin? Or listen to a girl scream as you rip her guts out, because you will. You and me, lover. We're gonna have a grand old time.
9x15 - #Thinman
- Roger murders Casey because she wouldn't go out with him. Even more terrifying, this sort of thing is Truth in Television.
9x21 - King of the Damned
- Dean slowly slipping into a homicidal mindset after getting the First Blade.
9x23 - Do You Believe In Miracles?
- Perhaps the most horrific moment in Supernatural: Demon!Dean is born.
- Dean fighting the Jerkass boyfriend outside the bar. He roughs him up, yeah, okay but then he keeps going. And going. You can practically hear the man's skull cracking, and Dean just keeps going. By the time he stops, the poor bastard is barely conscious.
10x07 - Girls, Girls, Girls
- Rowena's Attack Dog Spell makes its first appearance here. Basically, it completely screws your brain and causes you to bleed from the inside as you're bound to do anything Rowena orders you to do. Horrifyingly, the spell is virtually invulnerable (the only person who can remove it is Rowena herself) and, as the finale shows, affects freaking angels.
10x09 - The Things We Left Behind
- The loan sharks should not have pushed Dean too far
10x13 - Halt & Catch Fire
- The episode has a lovely scene where the ghost of the week cranks up a kid's music so loud that it causes it essentially turns his brain to mush and causes his eyes to burst out of their sockets, complete with blood streaming from his eyes. Kind of brings new meaning to the term "death metal."
10x22 - The Prisoner
- Dean, on full Roaring Rampage of Revenge mode, effortlessly massacres the entire Styne family and returns to the bunker, where he kills not only Charlie's killer and the grunt with him, but the kid they had brought with them because, as a Styne, evil was in his blood. The worst part of it is the fact that he's so blissfully calm, with the same cold tone whether threatening someone or cracking wise. The worst part is when Dean at the beginning says he isn't sure if it's the mark warping his mind, or his own repressed rage at Charlie's death. Even worse, killing the boy is practically a callback to Cain wiping out his descendants, even an innocent child, just because of the potential the boy had to be evil. Dean is now just a pair of black eyes away from being the same as the Father of Murder.
10x23 - Brother's Keeper
- At the end, when Darkness bursts out of the ground like a gigantic demon cloud, spreading outward and consuming everything in its path, including the Winchesters
- Everything about The Darkness is heavy Nightmare Fuel. It took God and all the Archangels: Michael, Lucifer, Raphael and Gabriel, just to imprison The Darkness, meaning that even together five of the most powerful beings in creation could not kill it. Repeat; GOD could not kill this thing. And now it's loose
- In addition, there's the fact there's no dialog from this thing. No ominous words. Just an unending, unearthly screeching.
- What's more is that even Death is afraid of this thing. Remember, Death considers Lucifer to be a bratty child throwing a temper tantrum, God!Cas a wannabe, sees the Leviathans as amusing, and claims that he will reap God. The Darkness? He refuses to reap the person carrying the Mark of Cain not because he can't, but because if he did, he would release the thing.
- Fridge Brilliance after you watch Season 11. Of course Death fears the Darkness. She does not know him, which means that she was locked away before he came into being. Death received the knowledge about her indirectly, probably through God, as he and the Darkness have never met eye to eye. Lucifer, God!Cas, the Leviathans, even The Big G are all under his watch. The Darkness is not.
- The Darkness infects people encompassed by its initial release and slowly turns them into amoral monsters with black veins running from their hearts up to their heads. They know it happens, they can spread it just by spilling blood onto others, and they have virtually no will of their own.
- The baby which Dean and Sam save in this episode? Her name is "Amara". Anyone who has listened to news leading up to the premiere immediately realizes that the baby is the Darkness in human form. If they haven't, the Mark of Cain on the baby's shoulders will tell them.
- Crowley is informed of the release of the Darkness, and we learn that it is only considered to be a fairy tale by demons. The scary part? Soon after the release of the Darkness, all of Hell heard screams echoing from Lucifer's Cage. In all likelihood, BOTH Michael and Lucifer were screaming in horror, meaning The Darkness is so wicked that two of the most dangerous beings in the Supernatural universe are terrified of it.
11x02 - Form and Void
- Amara literally eats souls. No wonder Michael and Lucifer were screaming from the Cage when she was let out.
- The episode ends with Crowley bringing Amara more victims, including children.
11x03 - The Bad Seed
- After a group of witches reject Rowena's offer to join her new Coven, Rowena casts a spell from the Book of the Damned that causes them to erupt in sores, boils, etc. and reduces them to dust.
- Amara begins to eat the souls of Demon, which Crowley provides to get on her good side, but he is seriously reconsidering his plans after she eats her first nanny's soul. By the episode's end, Amara is now an adolescent and says she is still hungry. And Crowley is right in front of her. You better ditch Hell, Crowley, and do it quickly.
11x06 - Our Little World
- The Reveal that happens during this episode: The Darkness is God's sister.
11x09 - O Brother, Where Art Thou?
- The opening scene. The Darkness comes across an evangelist gathering and taunts them before she wills a fountain nearby to spit out blood. Oh, and summoning a dark cloud that burns everyone present. The evangelist asks if she is God testing for their resilience. Nope, He is not the only one in town.
11x10 - The Devil in the Details
- Lucifer got out from his cage. And he is in Castiel's body.
11x17 - Red Meat
- Of all the ways that Sam has / almost died, being slowly smothered to "death" by a frightened and paranoid man they had just saved is probably the most gruesome way he could've gone.
11x18 - Hell's Angel
- Amara directs an attack towards Heaven. Cut to Heaven, where the angels can only watch helplessly as a mass of black smoke strikes them down like bowling pins (in first-person view!). And yes, this is Heaven we're talking about. The safest place in the universe is being trashed to the ground. Is it any wonder that The Darkness is The Dreaded?
11x20 - Don't Call Me Shurley
- It's awesome as well, in-universe and from an acting standpoint, but the second Chuck goes still and suddenly we're confronted with GOD. As in, the one that wiped out the world once, that destroyed Sodom and Gomorrah. It's a small shift, but VERY chilling.
- God tells Metatron that he created worlds to try to prove to Amara that they could be something better, showing her that they didn't need to be alone. She responded by destroying them. How many times did it happen?!
- The infectious fog from the season premiere returns, and is just as terrifying as before, especially when Amara uses it to communicate through one of the infectees. Even worse, it's no longer black smoke. It looks just like normal fog, which means people wouldn't even know they've been infected, or even to stay away. At least people with a bit of sense would stay away from the ominous black smoke.
11x22 - We Happy Few
- Everyone teams up to beat the Darkness. The witches first blast her with electricity. Result: she is mildly annoyed and makes the spell backfire on them. The angels collectively subject her to a Holy Hand Grenade. Result: she comes out none the worse for wear. The demons physically harm her directly. Result: she is weakened, yay!...except not. She enters the Men of Letters bunker, limping but still in power, as the Winchesters, Lucifer, and God try to seal her back into the Mark of Cain. Result: every single one of them is curbstomped and the Darkness even makes sure that they lose their only hope when she mortally wounds God.
- We only see the aftermath, but good lord whatever Lucifer did to Rowena will definitely make you squeamish. He completely burned her down to the bones, all while bashing her skull until it tethered away. What we see is a charred skeleton on the floor with red marks and blood scattered everywhere.
- As if all the tearjerkers in this particular episode weren't enough, the final act has Sam following burning footprints into the nursery that Kelly set up earlier, where he hears a ringing angelic frequency. He looks and sees someone...or something...huddled in a dark corner. He moves closer, then stops and gasps at what he sees: A small, naked young man who gives off Glowing Eyes of Doom as he smiles evilly at Sam.
- Castiel being confronted by the Shadow (as it's identified in the following season's "Byzantium"), the "friendly neighborhood cosmic entity" that rules the Empty that takes on Cass's form in order to talk to him because seeing his true form will make Cass "claw his eyes out." It's not long before Cass becomes deeply unnerved by this thing that looks like him, demanding with barely-contained fear that it get away from him. Instead, the Shadow decides to mind rape Cass, sending him to his knees. Misha Collins' screams of pain as he's telepathically violated will stick in your mind.
13x7 - War of the Worlds
- Parallel!Michael. Unlike the version of Michael from the main reality, who was willing to cause the Apocalypse but wasn't inherently evil, per se, this version of Michael is unrepentantly evil to extreme extents, taking pleasure in torturing Lucifer, expressing pride in what he has done to his reality, and makes it very clear that he will do it to the main reality too if he manages to cross over into it. He scares Lucifer so much that the latter goes to Castiel and begs him for help in stopping Michael.
- Also, the torture scene at the beginning of the episode. Michael shows no remorse or regret for his actions, and takes pleasure in causing Lucifer pain. Lucifer's bloodcurdling screams don't help, either.
13x09 - The Bad Place
- The titular Bad Place. It's an alternate dimension populated by monsters, similar to Purgatory...except it's worse. The final scene of the episode has Sam and Dean standing in a giant, dinosaur-like footprint, and as they head out into the jungle, we hear a loud roar...and even louder footsteps.
13x10 - Wayward Sisters
- The kaiju that finally makes it appearance just as Dean and Sam are escaping.
13x17 - The Thing
- If anyone thought the Leviathans and the Shadow were the only Eldritch Abominations in the Supernatural universe, then this episode proves them wrong, as Sandy, the woman the Winchesters are trying to help, turns out to be possessed by Yokoth, self-proclaimed "Star of Madness," "Ravager of Galaxies," and "Mother of Faceless Hordes." Worse, she wants to summon her mate, Glythur, to the main universe and have him possess Dean.
- What little we see of Glythur is not a beautiful sight.
13x23 - Let the Good Times Roll
- Lucifer's Villainous Breakdown after Jack declares he is not his father on learning that Lucifer cut a deal with Michael to return to the main universe and leave with Jack while Michael gets to raze Earth is terrifying. It's actually very similar to how Ego treats Star-Lord in Guardians of the Galaxy Vol. 2. He screams in his son's face (causing Dean, Sam, and Castiel to cover their ears in pain while he's at it), pretty much disowns the boy himself, then uses his blade to cut Jack's neck and siphon his power.
- In order to defeat Lucifer, Dean says "yes" to Michael on the condition that it's a one-time deal and that he remains in control of his body. Following a Hope Spot after Lucifer bites it, Michael clearly starts to fight from the inside, with Dean groaning "We had a deal!" Finally, Michael takes him over completely, smiles, says "Thanks for the suit," and disappears.
- The final shot of the season: Michael giving off Glowing Eyes of Doom as he looks right at the camera a la the end of Michael Jackson's "Thriller" and makes a Psychotic Smirk.
- The ending: A distraught Nick, fresh off of murdering the man who was possessed by Abraxas (who murdered his wife and son) and realizing he enjoys his murderous deeds, prays to Lucifer, who manifests within The Empty as a black skeletal shape before displaying glowing red eyes that look right at the camera before the Smash to Black.
14x17 — Game Night
- Nick works a ritual to summon Lucifer from The Empty, and Lucifer manifests as a winged humanoid comprised of swirling black matter encasing white light, all the while showing glowing red eyes.
14x19 — Jack in the Box
- Jack causing worms to eat a preacher's face and body from the inside out. Yeech.
- The many usages of the Creepy Child.
- There's something skin-crawlingly freaky about the combination of a demon with a jolly old Slasher Smile (particularly if they have glowing eyes), just because you know they're contemplating how many fun ways they're going to torture you to death.
- Most humans (even the possessed ones) who look at the true form of an angel will have their eyes burned out and can even die from it if the angel is powerful enough.
- The anime version can get away with a lot more gore than live-action, and the creators knew it. Notably, the adaptation of "Devil's Trap" cut out the car crash at the end since Dean getting tortured by Azazel was sufficient to hospitalize him.
- Lucifer, any time really. First, he isn't the "devil" most people perceive. He's brutally honest, straight up with the Winchesters (and especially Sam) about his plans. Problem is, there's nothing they can do to stop him. Even the Colt, which was said to be able to destroy just about anything, can't kill him. He's just a really nice guy who just happens to have the end of all human life on his agenda.
- In general, Soulless Sam in Season 6. Imagine having a brother/sister who's been dead for about a year, then suddenly comes back and their behavior is just off. They keep pretending to be fine and assuring you nothing's wrong, but it just doesn't seem right, their behavior is cold and careless, it looks like the person you knew and were close to but it just isn't them and you FEEL it. That must be how Dean felt about his brother coming back soulless from Hell. For some people, this might be Paranoia Fuel or generally just creepy.
- The Comic-Con trailer for Season 10 finally reveals a hint of what Demon!Dean will be like, and he's freaking terrifying. Stalking Sam through the bunker, trying to kill him with a hammer, and all the time taunting him like every Demon enemy the Winchesters have ever faced has done to them. Also scary because this trailer confirms that the old Dean is gone, and he may not be coming back.
