History NightmareFuel / SCPFoundationSCPs3000To3999

** Classic ''WesternAnimation/TheSimpsons'' episode "Marge Vs The Monorail" isn't bad at first, with members of 3922-A arriving in Springfield during the last part of the "Monorail" song at the town hall meeting, arresting Lyle Lanley and explaining his crimes to the townspeople. They then arrest the criminal citizens of the town, such as Snake, Mr Burns, etc and has them perform manual labor to construct a safe and functional monorail... with it's maiden voyage featuring ''Lanleys execution'' by tying him to the tracks and running him over with the monorail. And the people of Springfield are forced by armed guards to ride the rail and take part in it.

** It's similar to SCP-2998 in its presentation; it starts off as something very simple, weak, and pathetic, and then as you advance in the iterations it is slowly revealed to be more and more. At first, it's just described as a shared memory experienced by 85% of the prison population in South Rock Penitentiary in Lafayette, Indiana of the person affected getting into an argument with a friend. Next iteration, it turns out to be a Euclid-class SCP; it's contagious, and the argument was about a new child at the school, a Slovakian immigrant named [[EnfantTerrible Lily Veselka who is described as appearing anemic]] and also has pale blonde hair. We also get something about "Project Lethe". The third iteration, it’s Keter and turns out to be a highly protean MindVirus capable of altering and manipulating ''almost all'' memories in its hosts, allowing it to exert a high degree of control over them. "Project Lethe" turns out to have been a typical inhumane Foundation experiment in which a girl, the ''real'' "Lily Veselka" was {{Mind Rape}}d using highly invasive equipment as part of a project to research better ways to manipulate memories. She was somehow turned into the aforementioned MindVirus, a ''living idea'', which [[YouCannotKillAnIdea cannot die]] and is almost impossible to contain or quarantine. And she is ''[[TheDogBitesBack angry]]''. By the final iteration, she has taken over 78% of ''all human beings alive''. Even the Foundation members aren’t immune; the number of [=O5s=] left gradually dwindles until there are only two left, voting against each other about whether to cryptically "restart". In other words, most people alive are under control of a barely-sane little girl, and it's ''[[NiceJobBreakingItHero all the Foundation's fault!]]'' Pretty much the only saving grace is that it is classified as Keter instead of Apollyon, implying that there is at least ''some'' chance of somehow reversing it.

--> '''Bridget Callaghan:''' ''The Lord God sent Jesus Christ, his only son, to suffer and die on the cross. And we, the Foundation, will throw one of our own to the Lions for all eternity to undo all Christ died for. An eternity of suffering to erase a sacrifice. It isn't a fair price, but nothing is.''

* [[https://scp-wiki.wikidot.com/scp-3008 SCP-3008]] A Perfectly Normal, Regular Old IKEA: Imagine your bad luck - you drove to a local [=IKEA=] to buy some flat-pack furniture, and now you're lost and confused in a PocketDimension that seems to stretch on forever. At first, it seems like a paradise - well, as close to paradise as an [=IKEA=] can get. The cafes are always stocked with food, and there's plenty of assembled furniture or boxes to rest on. If you're lucky, you might find "tribes" of other people who ended up inside 3008, having banded together to form rudimentary civilizations. Everything changes [[KillTheLights when the lights go out]]. The previously docile race of SCP-3008-2, humanoids dressed in [=IKEA=] uniforms, become vicious shambling horrors that seek to attack any other life-forms within 3008, all while uttering phrases such as "[[ApologeticAttacker The store is now closed, please exit the building]]" [[MadnessMantra over and over again]]. You'd better hope you, and any friends you might have made during the 'day', can survive each horrifying night. There's also the fact that the exit always bounces around. And to make matters worse, the Infinite IKEA connects to [[AlternateUniverse other universes]]. Your odds of escaping are extremely slim, and even if you do escape, there’s no guarantee you’ll end up where you came from. If the Foundation happens to pick you up to debrief you and administer amnestics, you’re in the original universe, but you could show up just about anywhere instead.

-->The nightmare began a year ago, and it still won't stop. In it, my arm is wet with blood, the knife in hand — glittering like a brilliant, shining ruby. My heart beats like a drum; before me, I see the faces of strangers, contorted in agony, screaming for mercy. A woman. A man. Children… three girls, and a little baby boy. I do not know them. I cut them open. I cut them open, and then I eat their hearts.

-->I know it's just a nightmare. But it feels so real, so vivid… and there are times when I swear I can taste raw meat on the back of my tongue. When I can feel it slide down my throat, into my belly.

-->I've lived a long, lonely life. I have never known friends or family… so why do I live in a house with so many rooms? Why does each room fill me with guilt and dread? Why can't I bring myself to go down to my basement — why does it smell like rotting flesh?

-->And why do I own a crib?

-->My nightmare took place under the house. I've never gone down to look. I'm too afraid. If you're reading this, then you'll have to look for me. Maybe you'll find nothing. I pray you find nothing.

-->Either I'm crazy or I'm the Devil.

-->Please, God, let me be crazy.

-->'''707-09:''' Oh lord. That's your face. Marsh, It's got your face.

--> '''Captain Kuznetsov:''' ''We were fools. The void isn't a region where spacetime is ruined; it's the source of the tear itself. Spacetime itself is rending itself apart and we're seeing echoes of every timeline in the past and future. [[CosmicHorrorStory Time is an ouroboros, devouring itself, again and again, only to be reborn.]] I saw all of it. All of the times we tried to stop it in the past. All the times that I tried to stop it in the past. And the future. This happens again and again until we get it right. Over and over again, we try and try to fix it. All times blend together until we reach singularity and all is lost. The tear opens more holes everywhere in reality, and the anomalies appear faster and faster, but containment is only delaying the inevitable. The inevitable cleansing of the slate. [[DespairEventHorizon I saw all the timelines. And we haven't stopped it in any of them. Bogoroditsa. We have seen into the abyss, and by God, it hates us.]]''

-->''[Undulating, it thinks.]''

* [[https://scp-wiki.wikidot.com/scp-3519 SCP-3519]], These Quiet Days, is a contagious hardline belief that the world will end sometime in March 2019. Those infected firmly believe that an impending apocalypse is inbound (despite Foundation testing [[BrutalHonesty assuring that the possibility of such a thing happening is 0.015%]]), and are DrivenToSuicide, believing that [[BetterToDieThanBeKilled whatever truly is coming, it'd be better to die before that.]] Unfortunately, it gets worse for the Foundation and GOC. It starts spreading, and infecting large amounts of the Foundation and [=GoIs=], all while the suicide rate climbs. The Foundation, too, gets affected, with Foundation staff dying to the point where [[YouAreInCommandNow a junior researcher is automatically promoted to O5]][[note]]There are several ranks between those two, and under normal circumstances, there are ''years'' between one promotion and the next. O5 is the highest rank in the Foundation, and there are only 13 of them at any time, compared to the hundreds of lower-ranking staff.[[/note]]. In the end, the entire human population kills themselves off, with the said researcher being the lone survivor.[[note]]It's heavily implied from the Foundation that 3519 infection that the K-Class scenario is, in fact, SCP-3519 slowly killing off the population.[[/note]] Even worse, it's implied that, since the article is tagged "fifthist" and the first known instance of 3519 infection was highlighted by Operation Stargazer as containing heavy SCP-1425 influence, the infection was engineered by members of the Fifth Church, and spread using the Star Signals book. This means that the Fifth Church actually ''[[TheBadGuyWins won]]'' for real with the book this time.

** Luttermann's description of SCP-3004-1 is [[EldritchAbomination beyond disturbing]]. Not only is it huge and [[BrownNote physically hurts to look at and listen to]], even as a disembodied soul, but it appears as many things at once: a giant bug, an old man, a cicada on a cross, stained glass and wood stretching into infinity, all seeming to overlap. It also tried to speak with him, opening its mouth and showing him [[FictionalColor a hideous rainbow of colors he'd never seen before]] before going directly into his mind. Not only did it begin prodding around his very memories with its teeth and feelers, but he learned its motives: [[AGodIAm SCP-3004-1 believes itself to be God]]. Not ''a'' God, but ''Jehovah Himself.'' And it was happy to see him, hoping Lutterman was pleased with everything SCP-3004-1 had provided it. It thinks it's giving us what we want, but it has a weak connection to our reality and also doesn't understand similes or metaphors; it focuses on the pain and sacrifice aspects of Christianity without knowing what any of it means. It assumes humans love suffering and doesn't realize we don't come back to life. And Luttermann is terrified of how much more information it has now thanks to him, and that if it's not God, it may very well become soon.

** The Foundation quickly learns that despite the media 3922 enters being fictional, they can take things from those universes if it would help them. The event that causes the Foundation to realize this? They played [[Film/ANewHope Star Wars]], and the 3922 entities KILLED DARTH VADER, CAPTURED THE DEATH STAR, AND TAKE IT WITH THEM. The Foundation severely punished the researchers responsible, since they just gave a space station capable of destroying planets to an unknown organization. Soon after, they pre-emptively ban media with powerful individuals in it when someone suggests playing DragonBallZBattleOfGods, pointing out that even the weakest fighter there is capable of tending GALAXIES apart.

* [[https://scp-wiki.wikidot.com/scp-3513 SCP-3513]] "The Brain That Ate Itself" is a region of space in Rocky Crest, Windhoek, Namibia where when any organism with a brain enters it starts developing a beak-like nub on [[BodyHorror their brain that starts eating the brain matter]] which leads to some unknown place. Investigations into where the beak leads have been weird, to say the least and seem to lead to more hostile reactions from the beak. In the first, the recording camera leads to the brain of another infected individual, who promptly dies from a stroke. In the second the recording device gets interrupted by the animal the brain was a part of getting processed at a meat plant. And in the final one molten metal starts erupting from the beak, the molten metal is reported to be ''4000 K in heat''. Oh, and there is a picture of [[NauseaFuel one of the subject's brain with an array of such beaks]].

* [[https://scp-wiki.wikidot.com/scp-3199 SCP-3199]] "Humans, Refuted" is... to say the least, hard to describe. Besides the utterly ''unearthly'' photograph accompanying the page, these are humanoid chicken-like creatures with corrosive spit, but the real kicker is their reproductive process - they ''regurgitate'' massive eggs along with a blood-like substance. Each egg is virtually indestructible since they're composed of nacre, enamel, and an unknown crystalline carbon compound, and every individual is guaranteed to carry one egg at a time, this making these creatures difficult to eradicate. The other kicker is the fact that SCP-3199 instances also '''''scream in agony''''' whenever they lay their eggs. And there's the very real possibility that the beasts might overrun the human population if they're to ever breach containment due to their eternal pregnancies and the fact they can also reproduce asexually.

But the account of a pet being BuriedAlive by its owner ForTheEvulz, from the perspective of the said pet, is an effective reminder that yes, there is no limit to human cruelty, that manages to be chilling because, unlike the many, many anomalies the SCP Foundation handles, a human burying a loyal pet alive just ForTheEvulz has most likely happened many times before in real life…

** One specific test showed what happens if SCP-3922 influences the film ''Film/SaloOrThe120DaysOfSodom''. Apparently it depicted 3922-A instances taking out [[BigBadEnsemble the four masters]] via sniper fire before sending out squadrons to liberate the captives. It later shows the four 'masters' naked in a desert environment, disoriented and agitated where they are later picked up by the 3922-A instances and transported to their base of operations. Upon arrival the 'masters' are forcibly placed into semitransparent-gel filled ''[[PeopleJars Oubliettes]]'' where the rest of the film (which lasted for ''eight hours'') shows their [[AndIMustScream intense pain on their faces as they apparently feel every sense of agony and suffering within those jars]]. Instead of the SCP-3922 influenced film ending with the usual "YOU ARE WATCHED - YOU ARE PROTECTED - YOU ARE LOVED" message, it was replaced with a caption saying '''YOU HAVE BEEN WARNED''' under a red colored triple-crescent logo. This also shows that this SCP has something to do with [[https://scp-wiki.wikidot.com/scp-2922 SCP-2922]].

** Some of the containment procedures laid out are rather... unpleasant. One delightful example is a directive that Researcher Talloran's sister be brutally raped and mutilated, along with killing his parents and his pets in a specific order. Another one, dashed out, states that Researcher Talloran have a water hose [[{{Squick}} pump his body full of water through his rectum until he inflates like a balloon]].
