->''NO EYES"''
-->-- One of [[ApocalypticLog the eight notes]], ''VideoGame/{{Slender}}''

When things that should be harmless, or on the viewer's side, turn nasty, stripping away all sense of safety.

How can a viewer sleep easy in their bed, when they've seen how [[SlidingScaleOfLivingToys toys can come alive when all is dark]] and wreak unspeakable vengeance? What trust can they have that anyone will protect them, when they've just seen some [[TastesLikeDiabetes cheerful kid's program]] where a kid just like them was [[BodyHorror bloodily slaughtered]] by his own [[DemonicPossession possessed]] mother [[SugaryMalice as she sang a sweet lullaby?]]

This is perhaps the main reason why the MonsterClown, and especially BadSanta, are Tropes unto themselves. ''He sees you when you're sleeping...''

Paranoia, by definition, requires a level of suspicion and distrust. A monster chasing after you in broad daylight is probably not Paranoia Fuel, but a shape shifting murderer targeting you who ''may'' be hiding among your friends or family or [[ThingsThatGoBumpInTheNight the clothes in your closet]] most likely is. A good rule of thumb is if a show or commercial makes you double check the people or objects around you (or triple check, or quadruple check, or...) then it fits here.

One of the most psychologically devastating forms of NightmareFuel, because of its mental persistence and perception of [[InescapableHorror inescapable omnipresence]].

Other paranoia-inducing concepts include:

* [[TheIndexIsWatchingYou Invasion of privacy]] (from BigBrotherIsWatching to literal {{Telepathy}}): One of the most pervasive forms of Paranoia Fuel, since we basically know they can use our secrets against us (BlackMail, {{Room 101}}, etc).
* {{Hypochondria}} Fuel: playing on fear of [[TerrifiedOfGerms diseases]], [[TheVirus parasites]], [[MedicalHorror medical]] BodyHorror and the fragility of human biology in general. Do you know how easy it is to infect you on the microscopic level without you yourself noticing? Or how easy it is for one genetic disorder that can make you go AndIMustScream to suddenly [[FinaglesLaw go horribly wrong]] inside you?
* SlippingAMickey[=/=]TamperingWithFoodAndDrink: Do you know how easy it is to poison you? Goes hand in hand with Hypochondria Fuel above.
* AttackOfTheKillerWhatever[=/=]EverythingTryingToKillYou[=/=]MayContainEvil: betrayal by everyday items.
** Malevolent Toys: a subtrope of the above, specifically for toys.
** ChestMonster: That chest could contain (or even ''be'') a malevolent creature ready to kill you.
** ArtifactOfDeath: That beautiful ring you just found? Has a part of a radioactive source as its stone. That big metal thing your shovel hit while digging up your backyard? Is a UsefulNotes/WorldWarII-era land mine or other explosive device.
* {{Gaslighting}} is when someone tries to deliberately provoke a feeling of this upon you by altering your everyday environment without your knowledge, often with the intent of sending you crazy.
* FateWorseThanDeath or AndIMustScream: You can suffer one of them anytime, anywhere.
* [[NeverSleepAgain Good Luck Sleeping]]: things that attack specifically while you're sleeping.
* [[TheyLookJustLikeEveryoneElse They Could Be Anyone]]: Anybody could be out to get you, even your friends and/or family
* InvisibleJerkass: They're everywhere.
* [[TheConspiracy Sinister Conspiracy]]: There is a... well, [[ExactlyWhatItSaysOnTheTin sinister conspiracy]] at work in the world, and they have it in for you. Sometimes goes hand-in-hand with "They Could Be Anyone" above: ''Anyone'', even someone you trust, could conceivably be part of this conspiracy.
* MindManipulation: Especially if they control your loved ones, or worse, controlled you, made you do humiliating things and then subjected you to LaserGuidedAmnesia.
* NothingIsScarier: Sure [[ScareChord that sound]] could have [[CatScare just been the neighbor's cat]], but then again...
* ThroughTheEyesOfMadness: The very nature of the story is that you can't be entirely sure of what the truth is...
* [[ProperlyParanoid Justified Paranoia]]: Then again, once you've had absolute proof that something's out to get you, you have ''every valid reason to seek security.''
* [[SnowyScreenOfDeath Static on a television]], and its heir, the BlueScreenOfDeath.
* JustForFun/TelevisionIsTryingToKillUs

Fear of the dark is related, but falls under {{Primal Fear}}s.

Not directly related to the game ''TabletopGame/{{Paranoia}}''. Or, at least, that's what they want you to think.
