History NightmareFuel / LuigisMansion

*** Then there's the theme where King Boo is exposed, which is an even more warped and sped-up version of the final boss theme with these weird synth noises in the background.

* Considering the nature of the ghosts (and the mansion itself), one can wonder what rituals are done in the Astral Hall. The fact that the room itself prevnts you from going to the next room is as goofy as destabilizing. Speaking of the next room...

* The Boolossus ritual manages to be unsettling too, [[https://www.youtube.com/watch?v=TDEbC8lUwUI and the music mimicking the Boo radar doesn't help neither]]: the fifteen Boos composing it form a circle around Luigi, get closer and closer, then fly in the sky. After this, you can hear a sinister cackle, then a giant Boo with [[GlowingEyesOfDoom glowing eyes]] falls from the sky: while Luigi sees it ready to stomp him, [[TheFourthWallWillNotProtectYou you can see a giant ghost ready to jump out of your TV screen]]. Then, when the battle starts, you understand why it is called '''''Boolossus'''''.

Then, when the battle starts, you understand why it is called '''''Boolossus'''''.

* If you didn't catch enough Boos, one of these that compose Boolossus will show in front of the door leading to the balcony. Your Boo radar noise may shiver you in the dark corridor (at least in the UsefulNotes/NintendoGamecube version) and you may already know that Boos are [[KnightOfCerebus darker in this game]] that they usually are, but the conversation Luigi has with this one in particular easily gives the impression that Boolossus, outside of its battle form, is a HiveMind of some sort. Also, the moment when they push you back to the Hall can be shocking.
* The Boolossus ritual is unsettling too: the Boos composing it form a circle around Luigi, get closer and closer, then fly in the sky. After this, you can hear a sinister cackle, then Boolossus falls from the sky ([[TheFourthWallWillNotProtectYou and gets closer to your TV screen]]) before reaching the ground.

* When you enter in Guest room, you discover it is upside-down. At first, it looks like the furniture is glued on the ceiling, but the chandelier is on the floor, like if the ceiling was placed where the roof is supposed to be. The ghost sleeping in the bed, Sue Pea, doesn't take intruders' presence well:
--> "...Do not try to wake me... GOOOO AAWAAAAY!!!"
** Reading Sue Pea's description states [[PassedInTheirSleep "What was supposed to be a short nap turned into eternal sleep for the young Sue Pea."]] This also gets a lot worse when you realize the AdultFear of something happening to a child after they fall asleep.

* Pictured above, ladies and gentlemen, "the product of the mansion's fear and despair" [[KnightOfCerebus Bogmire]]. Unlike any other ghost, the guy doesn't even have [[EldritchAbomination any features that defined if he was alive or not]], looks more like a monster than a ghost and while he can be seen as a parody of "edgy for the sake of being edgy" outside of the game, he still holds a lot of mysteries and doesn't have any humorous elements...
** His introduction settles the tone: after having discovered the Graveyard entrance (yes, because you fight him in a '''''[[CreepyCemetery graveyard]]''''') and having fought skeleton ghosts who went out of the graves, the isolated one starts to glow. You get closer, then a thunder touches the grave and [[JumpScare Bogmire comes out]] with a [[ScareChord Scare]] [[https://www.youtube.com/watch?v=ZretP1qx2bs Chord]]. After that, the Graveyard becomes some sort of battlefield, then... something between ''shadows and slime'' comes out. And [[https://www.youtube.com/watch?v=paYabc3IO4Y the battle music cues]]...
** Like explained above, the "shadows" are between this and some sort of slime you have to suck up and throw on him. There is no explanation about how he can make these things.

* Reading Sue Pea's description states "What was supposed to be a short nap turned into eternal sleep for the young Sue Pea." This also gets a lot worse when you realize the AdultFear of something happening to a child after they fall asleep.

** The [[https://www.youtube.com/watch?v=xMUdg0FdCJs music]] that plays when you fight him isn't much better than the aforementioned music box; it is a perfect balance between goofy and scary. It becomes completely erratic [[https://www.youtube.com/watch?v=cuZsyDUKO5g when you suck him up]]: while the game's noises cover it, this crazy xylophone still amplifies this sensation.

* Pictured above, ladies and gentlemen, Bogmire. Seriously, the guy didn't even have any features that defined if he was alive or not, he looks more like a monster than a ghost, and the shadows...

You get closer, then a thunder touches the grave and [[JumpScare Bogmire comes out]] with a ScareChord. Then the Graveyard becomes some sort of battlefield, then... something between shadows and slime comes out.
** There's a mechanic in the game where if you push X, Luigi whips out the Game Boy Horror and can analyze things with it; one of these things are the hearts and inner thoughts of Portrait Ghosts, which can give you an advantage. Normal ghosts and Boos don't get any, along with King Boo and Boolosus. Who else? ''Bogmire''. He's the only ghost Portrait Ghost, save for the Boo bosses, to never get a heart thought. You'll never know what he's thinking... all you know is that ''"Bogmire is a product of the mansion's fear and despair."''. Yes, it is ''literally'' fear and sadness given form, and he wants to eat your face. Probably.
*** Adding to this, Bogmire is the only Portrait Ghost that has no programmed text or speech. And it doesn't help that you meet and fight him '''''[[CreepyCemetery in a graveyard.]]'''''

* The boss ghosts introduce themselves this way: they are close (or go closer) to your TV screen not only to frighten Luigi, but also to scare '''''[[TheFourthWallWillNotProtectYou you]]'''''. Their backgrounds also give the impression you are stuck in a parralel dimension.

* Hearing these portrait ghosts in the corridor legitimately makes you wonder what they can do in these rooms.

* The Boos are not the shy ghosts you were used to. They are closer to {{Eldritch Abomination}}s who share some "mysterious powers" they use only for the sake of a revenge plan.

** When you enter his room, the usual "dark room" music is accompanied by [[https://www.youtube.com/watch?v=PsVSeG6pEOQ a music box]].
** While his description implies that ghosts can reproduce, some fans have [[AdultFear darker explanations]]...

** The [[https://www.youtube.com/watch?v=xMUdg0FdCJs music]] that plays when you fight him isn't much better than the aforementioned music box; it is a perfect balance between goofy and scary. It becomes completely erratic [[https://www.youtube.com/watch?v=cuZsyDUKO5g when you actually blow him up]] and gives the sensation that you're fighting something beyond your comprehension.

* If you didn't catch enough Boos, one of them will show in front of the door to the balcony. Your Boo radar noise may shiver you in the dark corridor and you may already know that Boos are darker in this game that they usually are, but the conversation you have with this one in particular easily gives the impression that Boolossus, outside of its battle form, is a HiveMind of some sort.

* Your first introduction to Chauncey is this: after you capture [[MonsterIsAMommy Lydia]], a cutscene happens where the camera zooms in on a door whilst he's crying can be heard along with [[https://www.youtube.com/watch?v=y_VdFu83W00 a creepy music box tune]]...

[[folder:Area 1]]

** How is he described? ''"Bogmire is a product of the mansion's fear and despair."''
** There's a mechanic in the game where if you push X, Luigi whips out the Game Boy Horror and can analyze things with it; one of these things are the hearts and inner thoughts of Portrait Ghosts, which can give you an advantage. Normal ghosts and Boos don't get any, along with King Boo and Boolosus. Who else? ''Bogmire''. He's the only ghost Portrait Ghost, save for the Boo bosses, to never get a heart thought. You'll never know what he's thinking... all you know is that it is ''literally'' fear and sadness given form, and he wants to eat your face. Probably.

* [[EldritchLocation The Observatory Room]]. Maybe it's the fact that it seems like you're actually ''in'' space, the fact that there is ''actually'' a fake moon in there, and that the outside music actually ''plays'' in the room, pretty much confirming that you're in an alternate space of sorts.
* Madame Clairvoya. Some would say that there's nothing really scary about her, but... Well, one would think that the idea of being trapped in a painting forever would be a case of AndIMustScream, but she actually ''asks'' to be put there. She ''likes'' that? True Professor E. Gadd ''did'' say that ''some'' of the Portrait Ghosts were portraits ''to begin with'', but still...
** Maybe she's so horrified of having to serve Bowser [[spoiler:(except not)]] that she begs Luigi to give her the closest thing a ghost can get to a MercyKill.

* Some introductions to boss ghosts can be this: they are close (or go closer) to your TV screen not only to frighten Luigi, but also to scare '''''[[TheFourthWallWillNotProtectYou you]]'''''.

-->"WHO put out my candles? YOU, Mr. Lime-Green?"
-->"Well, dark rooms are dangerous around here... Yesss..."
-->"THEY love the dark...and now THEY will get YOU!! Bloo-heh!"
-->"Now you're in for it! Blugh-huh!"
-->"Just like little Red-Cap before you..."
-->"May you wander lost in the darkness...forever! Are you AFRAID of the dark, little man? Are you? Huh? Blah-hah! Here THEY are now!"

[[folder:Meta Horror]]

* The official GameOver isn't less creepy. Luigi falls to the floor while the screen goes black and white, [[https://www.youtube.com/watch?v=IrG8FdGyQ-8 the music plays]], and then the words "Good Night..." appear on bloody red letters. Which slowly go black and white themselves. This comment under the music track explains all the implications behind Luigi's defeat:

* [[ The title screen is even ''worse''. It is a disturbing silence [[JumpScare followed by the letters suddenly appearing]] and [[https://www.youtube.com/watch?v=r7YKE_DGIWs the music suddenly playing.]] After that, it fades in silence... If this shocks you, you're not ready for what's coming.
* The pause menu too; it has a door with Luigi's shadow hanging on it, creepily.

--> "This is what your failure has brought you:

You've killed Luigi
Mario's fate is sealed
The Ghosts able to trick even more people to come to the mansion.
Mario never returned to the Princess's Castle to save peach, gets kidnapped by Bowser, Bowser takes over the Mushroom Kingdom.
The toads in the mansion have nothing to come back to.

Game Over."
* Any scene with the Boos. King Boo gets special recognition, though.
* What about the music? It may be extremely catchy, but it's the icing of ''Luigi's Mansion''.
** It gets worse when Luigi whistles the game music and the ghosts in the area whistle a dark version of the tune.

[[/folder]]

** In addition, the Bowser suit is also terrifying in that ''it comes directly from nowhere''. While there are offhand mentions of Bowser, plus the RedHerring in that ''he'' may have been the BigBad, not King Boo, his sudden appearance -- which proves to be a ''hell'' of a JumpScare for Luigi -- feels almost as if King Boo is [[IKnowWhatYouFear personally digging into Luigi's greatest fears]], Bowser presumably being one of them. In addition, King Boo's portrayal of him is also very disturbing; the typically hammy, BoisterousBruiser of a king, depicted as a bloodthirsty, feral ''beast'' whose head can come off at will... not to mention, when his head does come off, ''it starts floating around with no pupils'', and starts firing ice balls at Luigi.

* The Boolossus rapidly approaching your TV screen.
* Bogmire giving you a jump scare.
* "[[TheSoCalledCoward Don't imagine that I'll flee]]... [[BadassBoast I'll fight you like a true Boo!]] [[AndIMustScream Now join your brother... inside the painting!]]"

* Reading Sue Pea's description states "What was supposed to be a short nap turned into eternal sleep for the young Sue Pea." This also gets a lot worse when you realize the AdultFear of something happening to a child after they fall asleep.
* Madame Clairvoya. Some would say that there's nothing really scary about her, but... Well, one would think that the idea of being trapped in a painting forever would be a case of AndIMustScream, but she actually ''asks'' to be put there. She ''likes'' that? True Professor E. Gadd ''did'' say that ''some'' of the Portrait Ghosts were portraits ''to begin with'', but still...
** Maybe she's so horrified of having to serve Bowser [[spoiler:(except not)]] that she begs Luigi to give her the closest thing a ghost can get to a MercyKill.
* The scariest part probably is when lightning strikes the mansion and cuts the power off. So every ''single'' previously lit room was now a miniature hell hole of never ending ghosts and can only be stopped by finding a portrait ghost looking at himself in a mirror and you're never told which room is he in. A little over half of the rooms of the mansion have mirrors.
** Made better by a couple small things: some rooms, while dark, don't have ghosts (such as the Foyer), and [[AntiFrustrationFeatures you can technically make a room safe for yourself by sucking up all the ghosts in it]]. The lights don't come back on, but the ghosts stop spawning. Also, a player may remember the parlor, anteroom, and wardrobe room that appeared to be [[{{Padding}} a dead end for just a key to an earlier door]] and think to go back there - but this still means that, even if you know where to go, you still have to go from the third floor back down to the first, and then through more ghost-filled rooms from there.
* Trying to capture Mr. Luggs, the ghost in the dining room, is downright disturbing. The fact that this enormous ghost is spitting fireballs, then calmly going back to his meal once the candles are relit, is just disturbing.
** Before you find the key to the dining room, you can hear the very inhuman sound of his eating every time you pass by it.
* There is a lighting oddity [[spoiler:in which Luigi's shadow appears as if he were dangling from a rafter by a noose.]] It's mostly the fact that it's an almost unnoticeable effect that appears for only a split second that makes it scary. Thankfully, it was fixed in the 3DS version.
* Bogmire. Seriously, the guy didn't even have any features that defined if he was alive or not, he looks more like a monster than a ghost, and the shadows...
** How is he described? ''"Bogmire is a product of the mansion's fear and despair."''
** There's a mechanic in the game where if you push X, Luigi whips out the Game Boy Horror and can analyze things with it; one of these things are the hearts and inner thoughts of Portrait Ghosts, which can give you an advantage.

*** Adding to this, Bogmire is the only Portrait Ghost that has no programmed text or speech. And it doesn't help that you meet and fight him '''''[[CreepyCemetery in a graveyard.]]'''''
* The [[spoiler:painting of the helpless Mario]]? Seeing him banging his fists while King Boo was laughing in the background was terrifying.
** How Luigi was [[spoiler:sucked into Mario's painting]] for the final boss fight, as it [[spoiler:transformed into Bowser?]]
* [[spoiler:Bowser's head going off his body when Luigi throws a bomb at him. Both scary AND unexpected in a Mario game.]]
** And then [[spoiler:when you capture King Boo, the Bowser suit collapses on the ground lifeless and without its head, [[OffWithHisHead as if it died from decapitation...]]]]
* What about the Safari Room with taxidermy animal heads? At first they're fine, like any you've seen in your life, but nothing immediately happens in the room, so you vacuum everything. When you get to those heads, '''they start nodding.''' It doesn't sound so bad, but it looks disturbing.
** This scene has reminded more than one fan of ''Film/EvilDead2''.
** They're [[UncannyValley more realistic than the rest of the game]].
** It doesn't help that in the 3DS remake, the deer heads' [[RedEyesTakeWarning eyes glow red]] and just stare at you.
* Your first introduction to Chauncey is this: after you capture [[MonsterIsAMommy Lydia]], a cutscene happens where the camera zooms in on a door whilst he's crying can be heard along with [[https://www.youtube.com/watch?v=y_VdFu83W00 a creepy music box tune]]...
** When you enter his room, the usual dark room music is accompanied by [[https://www.youtube.com/watch?v=PsVSeG6pEOQ a music box]].
** While his description implies that ghosts can reproduce, some fans have [[AdultFear darker explanations]]...
** Chauncey's face when [[HellIsThatNoise crying]] looks more like a NightmareFace than a baby crying.
** Not that the [[https://www.youtube.com/watch?v=xMUdg0FdCJs music]] that plays when you fight him is any better: it is a perfect balance between goofy and scary. It becomes completely erratic [[https://www.youtube.com/watch?v=cuZsyDUKO5g when you actually blow him up]] and gives the sensation that you're fighting something beyond your comprehension.
* [[EldritchLocation The Observatory Room]]. Maybe it's the fact that it seems like you're actually ''in'' space, the fact that there is ''actually'' a fake moon in there, and that the outside music actually ''plays'' in the room, pretty much confirming that you're in an alternate space of sorts.
* [[EvilLaugh King Boo's Laugh]], 'nuff said.
* If Luigi sprays ghosts with one of his elemental attacks without vacuuming them up, they fade away to nothing. Slowly. And their animations look like they're ''flailing around in pain'' while it happens. Sometimes they'll even ''whimper in fear'' just before they vanish.

* Pressing A at any time when not near an object will have Luigi call out for Mario. This is pointless and serves no real purpose, but as his HP drops, his cries get increasingly desperate and terrified. When you're down to 30 HP or less, Luigi will either say "Mario" in a bone-chillingly frightened whimper, or scream Mario's name in an absolutely horrified voice. These cries can either be humorous or downright terrifying. Especially the ones when he's about to die.
* King Boo's monologue at the end of the game conveys his utter ''hatred'' towards Luigi. What's worse, he remains completely calm, until he turns to Luigi... or since it's in a temporary Main/FirstPersonPerspective for the entire monologue... turns towards '''''[[TheFourthWallWillNotProtectYou you.]]'''''
* A good example of fridge horror is the Mansion's many attempts to stamp Luigi out or otherwise show that it's alive. Candles re-light themselves in hallways after Luigi puts them out, trap doors slam him into the wall violently, and one room [[spoiler:even leads into an impossible mockup of the night sky.]] All of these support E-Gadd's statement that the mansion is in fact a malevolent entity, and it's out for Luigi's blood.
!Meta Horror:

* The talking paintings in the first room after the foyer. They shake before they talk, which gives a creepy shaking door sound, they threaten Luigi, and then one says "Here they are now!" And the [[https://www.youtube.com/watch?v=YLZCDmAo87o music]] is this too... Thankfully, this is after you get the Poltergust, but still...
** Some FridgeHorror for you: we ''never'' find out who was talking here. Few of the Portrait Ghosts acknowledge knowing who Luigi is or having seen him before, and none of their personalities appear to match up with the voices speaking here. This is literally the only time in the game this happens, [[ParanoiaFuel and it never gets any sort of explanation]].
-->"WHO put out my candles? YOU, Mr. Lime-Green?"
-->"Well, dark rooms are dangerous around here... Yesss..."
-->"THEY love the dark...and now THEY will get YOU!! Bloo-heh!"
-->"Now you're in for it! Blugh-huh!"
-->"Just like little Red-Cap before you..."
-->"May you wander lost in the darkness...forever! Are you AFRAID of the dark, little man? Are you? Huh? Blah-hah! Here THEY are now!"
* The giant Bowser mecha[[note]]or corpse if you buy into the theory that Bowser is dead in this game[[/note]] King Boo uses to attack Luigi. And then its head blows off when you fire a mine at it...
** In addition, the Bowser suit is also terrifying in that ''it comes directly from nowhere''. While there are offhand mentions of Bowser, plus the RedHerring in that ''he'' may have been the BigBad, not King Boo, his sudden appearance -- which proves to be a ''hell'' of a JumpScare for Luigi -- feels almost as if King Boo is [[IKnowWhatYouFear personally digging into Luigi's greatest fears]], Bowser presumably being one of them.

** Then there's [[https://www.youtube.com/watch?v=kWK09UtYq7w the music]]; a chaotic, demented version of the regular boo-catching music. There's this [[HellIsThatSound weird noise]] in the background, which one [=YouTube=] commenter described as sounding like [[AndIMustScream Mario screaming for help]], and another as sounding like [[TheHyena King Boo laughing at you from inside his mecha.]]
*** Then there's the theme where King Boo is exposed, which is an even more warped and sped-up version of the final boss theme with these weird synth noises in the background.
* The Boolossus rapidly approaching your TV screen.
* Bogmire giving you a jump scare.
* "[[TheSoCalledCoward Don't imagine that I'll flee]]... [[BadassBoast I'll fight you like a true Boo!]] [[AndIMustScream Now join your brother... inside the painting!]]"
* Some of the portrait ghosts are not just scary because of what they look like, but how they even became ghosts in the first place. For example, there's those two twin children who love to play hide and seek. It is stated that because they both like to hide, the game usually lasts a long time. [[FridgeHorror Three guesses as to how they could have died]].
* Reading Sue Pea's description states "What was supposed to be a short nap turned into eternal sleep for the young Sue Pea." This also gets a lot worse when you realize the AdultFear of something happening to a child after they fall asleep.

* Dying in ''Luigi's Mansion'' is pretty creepy as well. Luigi falls to the floor while the screen goes black and white, and then the words "Good Night..." appear on bloody red letters. Which slowly go black and white themselves.

* The pause menu too; it has a door with Luigi's shadow hanging on it, creepily.
* The game select screen in the EU version. In the upper left corner, there's a text saying "Come in, the mansion is yours". Wait, and the text changes. "Come in, the mansion is ours".
** The US version instead has "Welcome to your mansion" which fades to "Welcome to our mansion"
** Also, there's the caption on the "Quit" Menu
*** "You'll be back" "And we'll be waiting"
* [[VoiceOfTheLegion The Nintendo logo screen.]] [[https://www.youtube.com/watch?v=nnFpv-YwvZE No, really.]]

* Chauncey's expression when he starts crying.
** Not that the [[https://www.youtube.com/watch?v=xMUdg0FdCJs music]] that plays when you fight him is any better.

* After you capture Lydia, a cutscene happens where the camera zooms in on a door whilst a baby's crying can be heard along with a creepy music box tune...*shivers*.
** His NightmareFace during his fight is freaky.
* The Observatory Room. Maybe it's the fact that it seems like you're actually ''in'' space, the fact that there is ''actually'' a fake moon in there, and that the outside music actually ''plays'' in the room, pretty much confirming that you're in an alternate space of sorts.

* [[https://www.youtube.com/watch?v=kWK09UtYq7w The final boss music]] has to be some of the most disturbing final boss music ever heard in a Mario game, and certainly the most terrifying.

* "Don't imagine that I'll flee... I'll fight you like a true Boo! Now join your brother... inside the painting!"

** How is he described? "Bogmire is a product of the mansion's fear and despair." THAT MEANS HE IS THE PERSONIFICATION OF THE WHOLE FRIGGIN' MANSION AND THE HORROR AND SADNESS WITHIN.

** In addition, the Bowser suit is also terrifying in that ''it comes directly from nowhere''.

* [[https://www.youtube.com/watch?v=aNmUoUrGrBY Boolossus' theme.]] *shudder*
** Eh...I actually think it's quite cool and badass.

* The Nintendo logo screen. [[https://www.youtube.com/watch?v=nnFpv-YwvZE No, really.]]
