* Whomever wrote the cheesy Christmas chestnut "Santa Claus is Coming to Town" must openly hate children[[note]]The song's lyricist, Haven Gillespie, ''did'' only have one child[[/note]]. The song never ever specifies what will happen to you if Santa sees you pouting... in your sleep... ''Shudder...''
** It gets worse. There's a version of the song by Johnny Mercer with some extra verses. While, once again, it's never specified what Santa does to naughty children, there are some very heavy -and deeply unsettling- implications:
---> If little Hal and Charlie don't mind their P's and Q's,
---> How sad! Too bad! They'll wish they had!
---> When the old boy (Santa) blows his fuse!
** [[http://www.vgcats.com/comics/?strip_id=231 This VG Cats strip]] might help allay the paranoia. Or ratchet it to new heights.
** This is played with in the Literature/{{Discworld}} novel ''Discworld/{{Hogfather}}'', where it's [[TheGrimReaper Death]] standing in for Santa. Imagine the terror of a skeleton in a Santa suit asking, [[foldercontrol]]

[[folder: Have you been naughty... or nice? ]]
Luckily, Death is a good guy, but the inherent creepiness of the above mentioned song is referenced directly. Of course, ''Hogfather'' isn't devoid of its own nightmarish moments.
*** [[TheNightmareBeforeChristmas A skeleton in a Santa suit?]]
** As [[CalvinAndHobbes Calvin]] put it: "Santa Claus: Jolly old elf, or CIA spook?"
** Or, in the words of MST3k's Mike Nelson: "Santa's tendrils reach far and wide. There is no hiding from the CLAUS organization!"
** How about hearing it [[http://www.youtube.com/watch?v=TADcPGxBZC8 sung]] by [[Series/{{Dexter}} Dexter Morgan]]? The cherry on top is when he reaches the line "I'm telling you why" and somebody in the audience asks why:
-->Santa Clause will ''kill you [[SerialKillerKiller if you're bad]]''.
* "Thriller" by MichaelJackson. Just watch the ending of the music video with the close up on his demonic face, combined with his "this is not an occult video" message at the beginning.
* "Somebody's Watching Me" by Rockwell has this trope as its general theme.
** Which led to its use in a 2008-09 series of GEICO commercials (the version used in the commercials is a remix by Mysto and Pizzi), where your money is watching you. With a big bug-eyed stare.
* TomWaits' [[http://www.youtube.com/watch?v=JaLjwSpZ6Cs "What's He Building In There?"]] defines this trope, musically; it's never made entirely clear whether the narrator of the song is just an over-paranoid and unstable person fixating on some innocent and harmless (if slightly reclusive and unconventional) neighbour, or whether the neighbour actually ''is'' up to something very sinister indeed...
* Tin Hat's cover of "Daisy Bell" turns a charming turn-of-the-century love song into a softly-voiced stalker's fantasy.
* "Subway Song" by TheCure. Especially if you are a woman and you have to walk anywhere by yourself at night. ''Turn around''.
** Not helping is the [[LastNoteNightmare loud scream closing the song]].
* The track "Faaip di Oiad" on the Music/{{Tool}} album ''Lateralus''. It sounds like a desperate, last-ditch final broadcast by someone who has discovered a number of terrifying things: Aliens are here. They've been here for a while. They've infiltrated many areas of the government and military. They have plans for this planet. And they're coming to get me because I know the truth.
** The name itself means something like "Voices of your God" in Enochian ("Angelic"). Eep.
** The pAper chAse's version-less Ministry and more Penderecki-2 versions, respectively titled It's Out There and it's Gonna Get You (which introduces We Know Where You Sleep) and We Will Make One of Us (one of their most ''upbeat'' tracks, leading into the track The House is Alive & The House Is Hungry.)
** Even more chilling is that the lyrics are a [[http://www.youtube.com/watch?v=ee3bld4lTG0&feature=related recording]] of a former Area 51 employee calling Coast to Coast AM, a radio show hosted at the time by Art Bell. It ''could'' be fake, the guy ''could'' be a great actor pretending to have vital information so horrific it causes him to break down and sob, and it ''could'' have been a satellite error that caused the radio station to go off the air. But we'll never know, will we?
** Another Music/{{Tool}} song, Lost Keys, seems to fit perfectly with Faaip de Oiad. The instrumentals don't clash, and the lyrics of Lost Keys start just after Faaip de Oiad's cut off.
* The ''Geto Boys''' classic song ''My Mind's Playing Tricks on Me'' is a very disturbing song of paranoia and Schizophrenia.
* "Every Breath You Take" by ThePolice on the surface appears to be a sweet, soft rock song - until one listens to the lyrics closely. '''"[[StalkerWithACrush I'll be watching you...]]"'''
* Music/{{Queensryche}}'s ''Gonna get close to you''. It's the 80's prog-metal version of ''Every Breath You Take'' -- only not nearly so subtle.
* ''Second Lives'' by Vitalic. Or rather, the video, where a camera is observing the users of a bathroom stall [[http://www.youtube.com/watch?v=fuwRxha8zSU and at the end Vitalic comes in and picks up his camera.]]
* The Music/{{Genesis}} song "[[http://www.youtube.com/watch?v=o02v0hkq3IA The Day The Light Went Out]]", a song about TheEndOfTheWorldAsWeKnowIt, in which ''[[EldritchAbomination something]]'' arrives here and puts out the light... and then, it prepares ''to feed''...
--> ''When they went to bed that night no one would have believed''
--> ''That in the morning, light would not be there''
--> ''The dark hung heavy on the air like the grip of a jealous man''
--> ''No place was there known to have been spared''
--> ''Then panic took control of minds and fear hit everyone''
--> ''The day the light went out of the daytime sky.''
* Judging from the lyrics, the song "Lost Northern Star" on Tarja's solo album after her [[CreativeDifferences falling-out]] with Music/{{Nightwish}} is probably supposed to be about a guardian angel. But when you [[LyricalDissonance actually]] ''hear it'', it comes across more like it's about SlenderMan.
* "[[http://thewildernessdowntown.com/ The Wilderness Downtown]]", AKA the music video for "[[ArcadeFire We Used To Wait]]", might make you slightly worried about your house being under surveillance. This is because it shows you surveillance photos of your house. Seriously.
** Mitigated somewhat by it only being Google Earth, but this doesn't make it any less of a TearJerker.
* "Papercut" by LinkinPark:
--> ''It's like I'm paranoid, looking over my back''
--> ''It's like a whirlwind inside of my head''
--> ''It's like I can't stop what I'm hearing within''
--> ''It's like the face inside is right beneath my skin''
* "[[http://www.youtube.com/watch?v=hqY3kASMFW8 Where Your Eyes Don't Go]]" by TheyMightBeGiants.
** And for that matter, "The Bells are Ringing" and "The Statue Got Me High"
* Does the song in PS2's ''The Thing'' called ''After Me'' by Saliva qualify?
* Planetary (Go) by MyChemicalRomance begins with 'There might be something outside your window, but you'll just never know'. Actually, the whole album and much of the promotional material are based around this trope.
* "Eye In The Sky" by Music/TheAlanParsonsProject:
-->''I am the eye in the sky, looking at you,''
-->''I can read your mind.''
-->''I am the maker of rules, dealing with fools,''
-->''I can cheat you blind.''
-->''And I don't need to see any more to know that''
-->''I can read your mind (looking at you)''
-->''I can read your mind (looking at you)''
-->''I can read your mind (looking at you)''
-->''I can read your mind.''
* Man, listen to the lyrics of "I Will Possess Your Heart" by DeathCabForCutie (or, for that matter, just the title).
-->''There are days when outside your window''
-->''I see my reflection as I slowly pass,''
-->''and I long for this mirrored perspective''
-->''when we'll be lovers, lovers at last.''
** Then, later:
--->''You reject my advances and desperate pleas''
--->''I won't let you let me down so easily''
* Music/PinkFloyd's [[Music/TheDarkSideOfTheMoon "Brain Damage"]].
---> ''The Lunatic is in my head''
---> ''There's someone in my head, but it's not me...''
* The ironically titled [[http://www.youtube.com/watch?v=GiT4FmcaRtY "Nothing to Fear"]] by OingoBoingo: "Hey, baby, let me give you some advice / The [[RedScare Russians]] are gonna pulverize us in our sleep tonight." And if they don't get you, then [[TheWarOnTerror Arab terrorists]] will. And if ''they'' don't get you, a lonely old man in a brand-new car will give you candy or ice cream before getting you wired on cocaine and then [[PaedoHunt raping you]]. And if ''he'' doesn't get you, then one of countless other things - Christianity, television, etc. - will just sap your will and warp your mind. Now go to sleep...
* Music/JudasPriest[='=]s "Night Crawler." A giant carnivorous worm from Hell can slither into your house, and it ''will'' see you in the dark.
* Music/BenFolds' song "From Above" provides the lovely little notion that you have only one true soul mate and you can pass by her/him every day without ever thinking about it. And you'll never truly be happy without him/her.
* Maybe it doesn't affect everyone the same way, but when I was a teenager I was listening to OurLadyPeace singing "The Birdman". On a walkman. At night. Alone in my room, as I was drifting off to sleep. Suddenly the singer whispers "I can't see him, but ''he's stalking my thoughts''." I didn't sleep that night. Or any night that line came back to my mind.
* "Muthufukka" by Music/{{Beck}}: "Everyone's out to get you, motherfucker!"
* {{Rammstein}}'s 'Stein um Stein' (which translates to 'stone by stone') starts off relatively unassuming, with the narrator informing someone he's going to build them a house... a house without windows or doors, where 'no light gets in'. Yep, he's going to wall them up and leave them to die. Sweet dreams.
* IronMaiden's "Fear of the Dark" is all about what could be hidden in the darkness...
-->Have you ever been alone at night
-->Thought you heard footsteps behind?
-->And turned around and no one's there
-->And as you quicken up your pace
-->You find it hard to look again
* [[https://www.youtube.com/watch?v=VrdQwKlbu4Q Turn Around, Look at Me]] by The Vogues gives you this feeling. It was featured in FinalDestination3, played for this trope in particular.
-->There is someone
-->Walking behind you
-->Turn around
-->Look at me...
[[NothingIsScarier Because you're sure there's someone there]]
