First Aired - 10/31/1991

This year's Halloween special comes from candy-induced nightmares: In "Lisa's Dream," Homer's monkey paw souvenir from Morocco makes wishes come true for his family and misfortune to befall everyone else, in "Bart's Dream," Bart's omnipotence forces everyone in town to be a StepfordSmiler or incur his wrath, and in "Homer's Dream," Mr. Burns builds the perfect plant worker and [[EpicFail uses Homer's brain to make the robot come to life]].

!!Tropes included in this episode:
* AcidRefluxNightmare: The FramingDevice is a series of nightmares induced by eating too much Halloween candy.
* ArsonMurderAndJaywalking: A variation as Burns describes his condition after being crushed by his deactivated robot.
-->'''Mr. Burns:''' Every bone in my body broken... vital organs leaking fluid... slight headache... loss of appetite... Smithers, I'm going to die.
* BazaarOfTheBizarre: Homer buys a monkey's paw in a Moroccan bazaar, [[TheLittleShopThatWasntThereYesterday that seems to vanish afterwards]], but it turns out he just looked in the wrong direction.
* BeCarefulWhatYouWishFor: "Lisa's Dream". Everything the family wishes for gets twisted around by the Monkey's Paw. Subverted when Ned gets it and everything goes right for him.
** Maggie's wish - A limo arrives, but only brings her a new pacifier, then drives away.
** Bart's wish - He wants the Simpsons to be rich and famous, which eventually results in the world at large getting sick of them.
** Lisa's wish - She asks for world peace, but the universal pacifism and lack of weapons makes it easy for extraterrestrial aliens to conquer Earth.
** Homer's wish - He asks for a turkey sandwich, but then it turns out the [[{{ArsonMurderAndJaywalking}} turkey is a little dry]].
** Though, after Flanders wishes to get rid of the aliens Kang and Kodo state that humanity will now build bigger and bigger boards with nails, until they destroy themselves.
* BitingTheHandHumor: After wishing The Simpsons to become rich and famous a large merchandising campaign starts up, causing the general public to grow tired of them. Otto complains: ''"Man, this this thing is really getting out of hand.'' Helen adds: ''"Is there anything they won't do?"''
* CatapultNightmare: The end of "Bart's Dream."
* CreatingLifeIsBad: Apparently, because it will only eat donuts and sleep on the job.
-->'''Mr. Burns:''' Oh, Smithers, I was wrong to play God! Life is precious, not something to be toyed with. Now take out that brain and flush it down the toilet!
* EasilyThwartedAlienInvasion: Parodied in "Lisa's Dream," Ned wishes that the aliens were gone. Cue Moe (and only Moe) chasing them away.
-->'''Kodos:''' He's got a board with a nail in it!
* EatTheCamera: Done at the end of Bart's nightmare, when he wakes up screaming (because of Homer ''kissing'' him, among all things.)
* GoneHorriblyWrong
--> '''Mr Burns''': It wasn't supposed to be this way! It was supposed to be a thing of beauty, not this abomination!
--> *cut to the Homer robot loudly snoring while asleep at its post*
* GraveRobbing: In "Homer's Dream," Mr. Burns and Smithers do this to find a brain for their robot. They find Homer sleeping in an open grave.
-->'''Mr. Burns:''' I feel like a kid in a candy store!
* InsufficientlyAdvancedAlien: In "Lisa's Dream," after humanity has gotten rid of their weapons, Kang and Kodos conquer Earth with slings and clubs.
-->'''Kang:''' Your superior intellect is no match for our puny weapons!
* JackassGenie: As usual, the Monkey Paw.
* {{Jerkass}}: Jimbo and Kearney threaten to egg Homer's house if he didn't hand over the candy bowl...then they egg it anyway and smash his pumpkin.
* MoralityPet: In "Homer's Dream," after the experiment is a proven failure, Smithers gets Burns to reverse the procedure on Homer.
* MultipleHeadCase: Mr. Burns's head is stitched to Homer's body.
* NotSoAboveItAll: Burns using the brain as a coonskin cap and yelling, "Look at me! I'm Davy Crockett!"
* OnTheNext: Parodied at the end of "Homer's Dream." Homer wants to go to a spaghetti restaurant, while Burns insists on attending a reception for the Queen of Holland.
-->'''Homer:''' Oh, I hate having two heads!
* OrWasItADream: The end of "Homer's Dream," where Homer finds Mr. Burns' head grafted to his shoulder.
-->'''Homer:''' I didn't wake up! It's all a dream! It's just a dream!\\
'''Mr. Burns:''' Oh, that's right. It's all a dream... or is it?! ''[[EvilLaugh (laughs)]]''
* PoliceAreUseless: Justified in both Lisa's and Bart's dreams. In the former, they could not stop the aliens due to Lisa's wish on world peace. In the latter, since Bart has powers that he uses whenever he is not pleased, all the cops could do is wave "Hi Bart!" when the bus passes them at [[Film/BackToTheFuture 88 miles per hour]].
* PuppyDogEyes: How Smithers gets Mr. Burns to return Homer's brain.
* RealityWarper: Bart in "Bart's Dream." Justified as it's a parody of the famous ''Twilight Zone'' episode about a boy who had similar powers.
* SharingABody: Mr. Burns's head is stitched to Homer's body.
* ShoutOut:
** The gravestones at the start show the tombstones of [[Disney/{{Bambi}} "Bambi's Mum"]], [[Music/TheDoors Jim Morrison]] (which has writing all over it and is being worshipped by hippies, which how Morrison's grave looks in real life), and Creator/WaltDisney (with icicles and frost all over it, a reference to the urban legend that Disney is cryogenically frozen).
** The children in Halloween costumes running past Homer's door are a reference to ''WesternAnimation/ItsTheGreatPumpkinCharlieBrown''.
** Lisa's dream is a reference to [[Literature/TheMonkeysPaw The Monkey's Paw]].
*** Homer being searched by the Moroccan police at the airport is a reference to the arrest of the drug smuggler in ''Film/MidnightExpress''.
*** Lisa wishes for world peace, which shows scenes of Argentina and the United Kingdom making up over the Falklands and people dancing in a large peace symbol to the tune of the hippie anthem "Get Together" by The Youngbloods.
*** Flanders' castle is a reference to the Disneyland castle.
** Bart's dream is a plot parody of the Series/TheTwilightZone episode "It's A Good Life". Even the narrator's voice spoofs Rod Serling's narration style.
** Homer's dream references ''Literature/{{Frankenstein}}''.
*** Bart and Lisa watch ''Series/TheTonightShow'' with Johnny Carson on TV.
*** Mr. Burns scolds the robot he created with the insult: "Clinking, clattering cacophony of collagenous cogs and camshafts", similar to [[Film/TheWizardOfOz The Wizard of Oz's]] line to the Tin Man: "You clinking, clanking, clattering collection of callousness junk!"
*** Homer and Mr. Burns's heads sharing the same body reference '' The Thing with Two Heads''
* TemptingFate: Marge warns everyone not eat too much candy or they'll get nightmares.
* ThisAintRocketSurgery:
-->'''Mr. Burns:''' Dammit, Smithers! This isn't rocket science, it's brain surgery!
