An Uncanny Atmosphere is basically when the characters/audience get the feeling that something is wrong in their environment. They don't know exactly what's going on, but they do know that something is definitely wrong.

For example: character walks into an area and gets the feeling that something is wrong there. Maybe everyone is gone? Maybe the inhabitants are all brainwashed zombies? Or, everything seems fine at first. But slowly, the characters/audience start to feel an undeniable sense of wrongness in the atmosphere.

Intentional use of the principles of UncannyValley are often applied to setting and background characters to increase drama or hint at conspiracy. The colors are a bit off (''Film/TheMatrix''), the people are [[StepfordSmiler too nice]] (''TheStepfordWives''), everything is [[CreepyCleanliness too clean]] or it's just [[ItsQuietTooQuiet too quiet]]. This may be a sign of a CrapsaccharineWorld.

Compare to UncannyVillage and NothingIsScarier.

* Creator/HPLovecraft was very fond of this trope. Whenever his settings weren't an EldritchLocation, there would still be a distinctly 'wrong' aura about them, which the narrators typically emphasized. [[Literature/TheShadowOverInnsmouth Innsmouth]] was a prime example, with its dilapidated structures and fishy odor hinting at [[TownWithADarkSecret something horrible behind the scenes.]] Other uses include ''The Colour Out of Space'' and ''The Whisperer in the Darkness'', just for starters.
* EdgarAllanPoe: The Fall of the House of Usher
* Some of Roald Dahl's stories, particularly "Literature/TheLandlady" where early on you can tell there's something not right about that woman and her "Bed and Breakfast".

[[folder: Video Games ]]

* ''Franchise/{{Bioshock}}''
* Peaceful Rest Valley from ''VideoGame/EarthBound''.
* ''VideoGame/{{Fallout 3}}'': Vault 112.
* ''{{Okage}}: Shadow King'' - The Highland Village. Everyone there talks in a distant, dreamy tone. Turns out [[spoiler:the entire village is a feeding ground for the Vampire Evil King.]]
* ''VideoGame/PaperMarioTheThousandYearDoor'': The Glitz Pit. About halfway through you'll be able to smell a conspiracy brewing.
* In ''VideoGame/PokemonXDGaleOfDarkness'', your return to peaceful Phenac Town from the first game is deliberately designed to invoke this. New players won't see what's wrong, but people who've played ''VideoGame/PokemonColosseum'' will take notice that all of the [=NPCs=] are acting contrary to their personalities in the previous game, and the roaming Pokemon are also all wrong (for example, the jogger lapping the fountain has a Duskull following him instead of a Castform). It's unsettling, but at the same time one has to wonder if the programmers just plain didn't look into how things were in the first game. And then you find out that [[spoiler:every single person in town had been kidnapped and replaced by a disguised Cipher member. [[ParanoiaFuel Yikes.]]]] After you've solved that problem, Phenac returns to exactly how you remember it from ''[[VideoGame/PokemonColosseum Colosseum]]''. Well played, Genius Sonority.
* The ''SilentHill'' series. When a character first enters the town, they notice that no one is around and even before they find their first monster, they know there's something wrong there.
* ''VideoGame/SuperMarioRPG: Legend of the Seven Stars'' - The Seaside Town. By talking to the villagers you'll eventually realize that something is wrong here. [[spoiler:You eventually find out that Yaridovich has kidnapped all the townspeople and has disguised himself as all of them.]]
* All of Termina from ''{{The Legend of Zelda Majoras Mask}}''.
** A more specific example is if you visit Romani Ranch on the third day. Romani's facial expression is bound to bring up some questions.
