Didn't think it was possible for a Disney series to venture into this territory? Ha ha, "Welcome to Gravity Falls" indeed.

[[folder:General]]
* The [[BlackSpeech creepy whispering]] in the intro, along with those unsettling chords and flickering subliminal imagery, and the dying/fading on the last note, from the intro will never cease to send a chill down your spine.
** [[spoiler:It's "Three Letters Back" in reverse -- the cipher for the initial end-of-episode codes. It eventually switches to other messages when the cipher changes accordingly.]]
* [[spoiler: ''STAN IS NOT WHAT HE SEEMS'']]
[[/folder]]


[[folder:Season 1]]
* Episode 1, "Tourist Trapped". A bunch of [[FairFolk gnomes]] wanted to kidnap and marry Mabel, a little girl, which is unsettling as it is. That's not even considering the fact they can be ''old'' even by human standards.
** They were rather feral when Dipper comes to rescue Mabel, one of them attempting to eat Dipper's face off.
*** And then there's the big gnome monster that they all form together...
* Episode 3, "Headhunters". [[spoiler:Wax Sherlock Holmes tried to outright ''murder'' Stan with an axe.]]
** [[spoiler:[[FridgeHorror Had Mabel not made a Wax Grunkle Stan, the real Grunkle Stan might have met his demise...]]]]
** [[spoiler: HE'S STILL IN THE VENTS.]]
* Episode 4, "The Hand That Rocks The Mabel", when Lil Gideon shows his true colours. He's unstable, violent and seems to believe that Mabel is secretly in love with him. Heck, he tried to [[spoiler: ''cut out Dipper's tongue and kill him'']] just to get to Mabel. And keep in mind Gideon is ''three years younger than Dipper''!
** It doesn't help for the fact that Gideon has the voice of [[WesternAnimation/TheMarvelousMisadventuresOfFlapjack Flapjack]] and while he sounds a tad goofy, it also proves to be quite unsettling.
* Episode 5, "The Inconveniencing", has ''so'' many...
** [[spoiler:'''POSSESSED MABEL''']]. It's creepy enough in concept, but actually ''seeing'' it...
** [[http://images2.wikia.nocookie.net/__cb20120605193113/gravityfalls/images/5/5c/S1e5_cooler_monster.png The cooler monster.]] ([[BigLippedAlligatorMoment Whatever happened to it, anyway?]])
*** It ''was'' presumably [[spoiler:just an illusion]].
*** Alex Hirsch's response when asked about the monster if it'll ever be explained? "No."
** When Dipper turns around and sees that his and the others' reflections have become ''skeletons''.
** The fates of the teenagers that the twins venture to the store with: Being trapped inside a television screen, a video game, a cereal box cover, and a hot dog ''[[AndIMustScream that's being cooked]]''.
** And judging by the sound effect and reactions of the characters watching, the cereal box one was a GoryDiscretionShot.
--->'''Cereal Box Bird''': I'm bonkers for eating you alive!
** More "GettingCrapPastTheRadar" than nightmare fuel. But it's really really surprising the show was allowed (being Disney) to get away with using the word "Murder" and showing two corpse outlines. DarkerAndEdgier Disney indeed.
* Episode 6, "Dipper vs. Manliness" we're introduced to the leader of the manotaurs! [[spoiler: Only for him to be DEVOURED on screen by the real leader SECONDS later.]] While on its own the scene isn't so bad, but you must think of how Dipper must feel knowing these creatures [[spoiler: REGULARLY eat their own as offerings]] It's implied that this isn't the first time this has happened. Doubles as a SugarWiki/MomentOfAwesome when he finally stands up to them however.
** When the Leader ''pulls a spear out of his chest'' with screaming and blood and everything. ''[[{{Squick}} Uhhh...]]''
* Episode 7, "Double Dipper", has two that particularity spring to mind. Firstly, the the copy of Dipper's (dismembered) arm bubbling and melting away, and secondly, [[BodyHorror Paper-Jam Dipper]].
** How about Dipper's dismembered copy arm in the first place? Think about it? A disembodied arm crawling towards you, not to mention the music that was playing in the background of that scene.
** [[spoiler:Paper-Jam Dipper welcomed his death. Apparently he was suffering from his deformities.]]
* Episode 9, "The Time Traveler's Pig", has [[spoiler:the Time Baby, a large headed, [[RedEyesTakeWarning red eyed]] baby that seemingly controls all of time.]]
* Episode 10, "Fight Fighters", [[AdultFear lands Dipper in a shockingly realistic "fight with a bully" scenario]], especially by Disney Channel standards.
** Rumble McSkirmish on a rampage in the real world has some of this too, in retrospect. He's basically acting exactly like you'd expect a character from a fighting game to act when loosed in the real world. (i.e. attacking everything in sight.) [[FridgeHorror Who's to say how many people might have gotten accidentally killed or maimed during this?]]
* Episode 11, "Little Dipper", has [[spoiler:Gideon return to thwart the Pines family and the Shack. He really loses his grip the whole episode and shows very {{Yandere}} tendencies.]]
** We also see [[spoiler:his mom, who seems to be very neurotic and dead-set on just vacuuming all the time. [[FridgeHorror Did Gideon drive her up the wall...?]]]]
*** He strikes some real {{Nightmare Face}}s, too.
*** The way Gideon screams at his parents, demands his father look him in the eye and grabs him by the face, etc., are all ''strongly'' reminiscent of a habitually abusive parent lashing out at a child rather than simply an outrageously bratty kid acting out.
-->'''Gideon's mother''': ''[[MadnessMantra Just keep vacuuming just keep vacuuming just keep vacuuming...]]''
** Then there's when he decides to shrink Stan...
-->'''Gideon:''' Heh heh heh...Hahahahah! WHAT AM I DOIN'!? I don't need ransom! I have ''this!'' I'll just shrink Stan and take the Shack by force! And if the rest of you get in my way... ''(Rips heads off Pines family figurines)'' SMASH!
* Episode 12, "Summer-Ween", has a monster who tasks Dipper and Mabel with bringing him candy, or he'll eat them. He's scary enough at the start, but his transformed state is even scarier.
** And to demonstrate he's not kidding, the Summerween Trickster [[spoiler: grabbed a random kid and ATE HIM WHOLE! And this is the first five minutes of the episode!]]
** The Summerween Trickster's actual face behind the mask.
** How much the Trickster looks like [[spoiler:[[Anime/SpiritedAway Noh-Face]] without his costume]].
** Stan's attempts to scare the two Trick-or-Treaters are kind of scary, even if the kids don't think so. His first attempt is to wear a mask that makes it look like his '''face is melting off his skull'''.
* Episode 13, "Boss Mabel." That poor, poor couple Dipper caused to go insane by looking into the [[DeadlyGaze Gremloblin's eyes]]. They're last seen carried away on stretchers in catatonic states, with their eyes wide in frozen terror. Yes, Disney openly admitted to MindRape on this show.
* Episode 15, "The Deep End", features a lifeguard who is [[SeriousBusiness so dedicated to his job]] that it's almost creepy.
** The [[http://gravityfalls.wikia.com/wiki/File:S1e1_dipper_with_signs.png dead, mummified looking merman]] seen in episode 1 becomes extremely unsettling now that the twins have learned merfolk are real, intelligent beings.
*** Most likely it's intended to be a reference to the Fiji Mermaids, a common carnival attraction about a century ago. Mind you, they were nightmare fuel in their own right, and usually consisted of a mummified ape sown together with a fish. Of course, the one shown in this episode IS human sized...
** The kid in the pool filter when you think about it for too long.
* Episode 16, "Carpet Diem." Soos is switched with Waddles, and while he's being hunted by Old Man McGucket, Waddles is off screen. Whatever he was doing, it resulted in a marriage proposal with a woman being so unbalanced that a mute, bumbling man with no indication of sapience can go from total stranger to marriage material in the space of a few hours -- and when he ''does'' start behaving like a human being, she's no longer interested.
** Some of the creepy expressions Waddles makes while in Soos' body.
** When Soos tells McGucket that he's a man trapped in a pig's body, McGucket replies: "That's what they all say..." in a very unnerving manner, suggesting he's [[FridgeHorror eaten other talking animals.]]
** [[ImAHumanitarian McGucket telling Soos he'll still eat him in his human body.]]
* Episode 17, "Boyz Crazy." The sole fact that [[spoiler: the producer of Sev'ral Timez has genetically engineered the band and KEEPS THEM LOCKED IN AN OVERSIZED HAMSTER CAGE]] is kind of frightening.
** The clones kept in test tubes. There was an adult, an older kid, a younger kid, a baby... and a fetus.
** Robbie brainwashing Wendy with his song. The backmasked message itself it pretty damn creepy, too:
--->'''Low Voice''': You are now under my control. Your mind is mine.
** Plenty of scare chords related to that above message.
** The manager of Sev'ral Timez. What a bastard. It's clear he's abusive to the people he creates.
** The shit-eating grin Robbie has on his face before he brainwashes Wendy with his song. He ''knows'' damn well that what he's doing is despicable and disgusting.
** Sev'ral Timez is released as babes in the woods. Candy says casually, "They won't last a week."
* Episode 18, "The Land Before Swine". When the Mystery Shack gang first comes across the pterodactyl's nest, ''several skeletons are seen nearby''.
** As the gang runs from the pterosaur, they pass a ''T. rex'' stuck in amber that wriggles its arms, suggesting that it might free itself someday.
** Also, Old Man [=McGucket=] [[spoiler: getting swallowed alive by the baby pterodactyl, and implied to have eaten his way out of it at the end.]]
** There's also the general fear of having a beloved pet being snatched away by a predator.
* From Episode 19, "Dreamscapers", we have:
** [[spoiler:Gideon ''winning''.]]
** The fact that Gideon wants the Shack so badly that he summoned a demon to do it. Not a "spirit" or a "monster" but an actual ''demon''. There's also the fact that the page about the demon in Dipper's book is bloodstained.
*** The way Gideon summons Bill is with ''backmasked words''. But if you reverse it, he's actually saying "Backwards message". Still doesn't make the actual scene any less creepy, though.
*** The fact that the unknown author of the journals specifically noted not to ''EVER'' summon Bill. Out of all the horrible things that haunt GF, this being scared the author the most. Its entirerly possible Bill is the "Him" the author speaks about in the first episode that is watching him.
** Mabel losing her cuteness...it's really not pretty.
** Gideon's glowing eyes and freaky incantation while summoning Bill.
** Bill knows [[http://youtu.be/TvWFY6mJpWA?t=1m lots of things]]... '''[[VoiceOfTheLegion LOOOOOOOTS OF THINGS]]'''
** Remember how Gideon was once angry enough to try to cut out Dipper's tongue with lamb shears? Bill [[TheToothHurts tears out the teeth]] of a deer and hands them to Gideon, who shrieks in horror and drops them all.
---> '''Bill:''' Deer teeth! For you, kid. [[LaughingMad Ahahahaha!]]
---> '''Gideon:''' Ah- ahhhh! You're insane!
---> '''Bill:''' Sure I am, what's your point?
** Dipper getting a hole blown through his body.
** Bill when he gets angry.
---> '''Bill:''' '' '''EAT NIGHTMARES!''' ''
** Bill leaving was incredibly creepy as well, complete with flickering and flashing imagery, and a healthy serving of scary sounds.
*** While he was leaving, his last words were "I'LL BE WATCHING YOU..."
*** Hell, just the fact that Bill wasnt ''actually defeated'', he decided to just leave, because he thought the Pines were amusing and worth keeping an eye on.
** TheStinger is the icing on the creepy cake. It's a view of a forest scene with "To Be Continued" written at the bottom, with an eerie remix of the theme song playing in the background.
*** If you look, you can see Bill's eye on some of the trees.
**** You can see his eye ''[[http://greenwithenby.tumblr.com/post/54901151462/hes-always-watching everywhere]]''
**** Take a look at Dipper's cap. [[FridgeHorror It's from the first episode.]]
** Before the episode even aired, Bill was a source of unnerving content. On Disney's website for Gravity Falls, the game "''Rumble's Revenge''" yields twelve special cryptograms. When transcribed, they read:
-->"i bet you're wondering who I a'''M'''."
-->"i don't give up answers easil'''Y'''.."
-->"i k'''N'''ow things. Fascinating things..."
-->"your reality is a game to me. And I like g'''A'''mes...."
-->"mischief is my '''M'''iddle name, but not my first....."
-->"th'''E'''re are six hints I will give you......"
-->"1. there is a secret soc'''I'''ety in Gravity Falls......."
-->"2. the Handyman know'''S''' more than he thinks........"
-->"3. gideon has '''B'''een searching for something........."
-->"4. what goes up '''I'''s sure to come down.........."
-->"5. dipper is p'''L'''aying with fire..........."
-->"6. i will be returning to Gravity Fal'''L'''s............"
* Episode 20, "Gideon Rises":
** The opening sequence.
** Gideon screaming at Waddles to get back in the corner, coupled with his terrified expression.
** [[spoiler: The giant robot Gideon]] definitely falls under UncannyValley.
** Gideon ''still'' retains his {{Yandere}} tendencies, and uses [[spoiler:the aforementioned Gideon robot to grab Mabel and demand she be his queen.]]

[[folder: Dipper's Guide to the Unexplained]]
* In "Lefty", Dipper spies upon a man who never turns right and literally does everything left. Then Dipper later gets him to turn around and [[spoiler:HE'S NOT HUMAN BUT A ROBOT CONTROLLED BY TINY GREEN CREATURES!!!!]] The huge [[spoiler:[[TheReveal reveal]]]] was really creepy and completely unexpected.
** And then [[spoiler:''THEY ALL COMMIT SUICIDE.'']]
* [[http://www.youtube.com/watch?v=96FEhn_N76Y The "Tooth" short.]] Or more specifically, the thing the tooth came from...
** [[spoiler: [[http://31.media.tumblr.com/3f972ba34bcb298717109a97b45936a6/tumblr_muu97iRipq1svxbupo1_500.jpg Here it is, if you're curious.]]]]
** The thing the tooth came from speaks backwards, and [[SchmuckBait if you are curious enough to translate it]]...
--> [[spoiler:"''You have disturbed my slumber. '''Enter my mouth, children! ENTER YOUR DESTINY!'''''"]]
** If you look closely when [[spoiler: The Head chases after the kids, you can see some SKELETONS hanging off the bottom of it. How many people died from this thing!?!]]
** Bear-O is a piece of work too.
* [[http://www.youtube.com/watch?v=NXrmRW_v1s8 The Hide Behind]] at the end of the short.
* Watching all of the shorts and then putting the pieces at the end of them together nets [[http://gravityfalls.wikia.com/wiki/File:Shorts_the_hidden_page.jpg this wonderful image]].
** Not to mention when you decrypt the Red Code along the edge, it spells [[spoiler: I WAS SO BLIND, HE LIED TO ME, THE DARKNESS IS NEAR.]]
[[/folder]]

[[folder:Shorts]]
* If you think about it for more than about a second, [[spoiler: Gideon's status in prison]] shown in the first Gravity Falls Public Access short becomes this. He's clearly got a huge amount of influence, and the people he's lording over are clearly pretty unstable, and coordinating a mass breakout is hardly beyond his means...
** That aside, the fact that a child who might be no older than 10 would be put in a maximum security prison with people who have probably done some horrifying things to end up there seems like a [[AdultFear big concern]].
* Octavia the 8-legged cow from "Mabel's Scrapbook". She looks harmless enough...until she zaps a passing eagle with her LaserEyes and eats it with her OverlyLongTongue.
-->'''Stan:''' ''Run.''
[[/folder]]

[[folder:Season 2]]
* In one of the trailers of season two, [[spoiler:Lazy Susan is seen on a payphone]] with [[spoiler:two men in face-concealing hoods approaching her menacingly]], all while creepy music plays.
** True to his word, Bill Cipher is [[ParanoiaFuel watching the twins.]]
* Episode 1, ''Scary-oke'', has a zombie invasion, [[spoiler:with poor Soos being infected and becoming a zombie.]]
** [[spoiler: Zombie Soos is made somewhat less terrifying by still being as goofy as he ever was.]]
** [[spoiler: The glove Stan puts on in the bunker has ''six fingers'']]
* Episode 2, ''Into The Bunker'' has the [[spoiler: Shape Shifter, which does [[VoluntaryShapeshifting exactly what its name implies.]] It tricks Dipper into thinking he's met the author of the journals, before revealing its terrifying, somewhat [[EldritchAbomination eldritch true form]] and trying to kill Dipper and take the journal. Dipper even discusses the fact that [[ParanoiaFuel if it got loose, it could turn into anyone and you would never know it.]]]]
** [[spoiler: What's even worse is that it displays a lot more of a malicious personality than a lot of other supernatural creatures. Unlike the numerous monsters that fall under TrueNeutral, to the Summerween Trickster and Pa and Ma who have a FreudianExcuse, to even Bill who's motives and end goal are highly questionable, the Shape Shifter is a horrifying monster who taunts Dipper about what may happen to him if he goes too deep, transforming into a horrified Dipper before he is frozen in a chamber. Soos even lampshades it with a "good luck sleeping at night."]]
-->'''Shape shifter (In Mabel's form):''' Should I be one, (takes Dipper's form) or the other? How about both? [[http://i5.photobucket.com/albums/y188/Hikari_saito/BodyHorror.png (transforms into an BodyHorror mixture of the two)]]
** [[spoiler: The build up to the Shape Shifter reveal was surprisingly creepy, even for this show! Dipper and Wendy, separated from Soos and Mabel, run into the "author of the journals". Everything's going fine, Dipper is happy they managed to find him and everything seems to be going okay. Then Wendy realizes that the man they're talking to is the [[OhCrap Mascot on the can of beans down in the bunker]]. Realizing how bad this is, Dipper tries to head out. And then the Shape Shifter takes quite a [[BodyHorror notes from]] [[TheThing1982 another certain shape shifting alien...]].]]
** One of the worst parts about the [[spoiler: Shapeshifter? He makes the exact same sound effect as the [[WesternAnimation/BuzzLightyearOfStarCommand Zurg-a-Tronic Megaray,]] the source of many kids from the 90s nightmares.]]
** The overall similarities to [[TheThing1982 The Thing]] also add a lot of FridgeHorror. [[spoiler:Wendy's ''bleeding'' after the initial fight with the monster...]]
** Whatever that [[spoiler: monster in the shadows was. It appears to be a spider, but [[UltimateEvil we never actually see it in full form.]] It's also mentioned to have regenerative properties...]] This is assuming, of course [[spoiler: that the monster wasn't Experiment 210 and the "author's" battle with it wasn't some sort of ruse to gain Dipper and Wendy's trust, such as shapeshifting part of itself into the "author" and ripping out the monster's tongue.]]
** [[spoiler: The Shapeshifter's last words.]]
-->[[spoiler: You think you're so clever don't you Dipper ? But you have no idea what you're up against. You will never find the author, and if you keep digging, you'll meet a fate worse then you can imagine, and this will be the last move you'll ever make. (''As the shapeshifter is frozen it takes the form of a screaming and terrified Dipper.'')]]
* The Golf Wars was essentially a really funny, light hearted episode, but it did have two moments; when the Lilliputtians [[spoiler:tie up Pacifica because they think Mabel would like them best if she had the chance to ''murder'' her instead (prompting another group to threaten to murder her golf tutor in retaliation), and when they all decide to work together so they can ''cut Mabel open''.]] Kind of a surprise.
** Franz in particular, as performed by Creator/PattonOswalt, is just so cheerfully sociopathic in everything he says, and - unlike many of the other villains - [[BlueAndOrangeMorality barely seems to understand he's even doing anything wrong]].
