->''"During the meeting, I was the perfect prince. The son my father wanted. But I wasn't me."''
-->-- '''Zuko''' has [[HeelFaceTurn a realization long in coming]]

The invasion is four days away, and Aang begins to feel nervous about confronting the Fire-Lord. Feeling that he is unprepared, he trains constantly and loses sleep, causing him to hallucinate and have nightmares. After three straight days, it takes the collaboration of Sokka, Toph, and Katara to get him to finally sleep and feel confident about facing Fire Lord Ozai.
----
!!Tropes:

* AdviceBackfire: Sokka's attempts to reassure Aang do ''not'' go well:
-->'''Sokka:''' Of course you're stressed; you've gotta fight the Fire Lord: the baddest man on the planet! And you'd better win, or we're all done for...
-->'''Katara:''' Sokka! That's not helping!
* AfraidOfNeedles: Aang, when Toph suggests acupuncture with a porcupine-like creature. The fact that the creature's needles have AudibleSharpness probably doesn't help matters.
* AnimeHair: Aang in his dreams.
* AnthropomorphicZigZag: Happens within the episode. Aang briefly hallucinates that Momo is [[SuddenlyVoiced able to talk]] - then returns to his normal chattering. Then Appa shows up, standing on two legs and talking to Momo, and Momo talking back to him. Then Momo puts on a robe, Appa puts on samurai armor, and they engage in a sword fight. When Aang's hallucinations end, they're back to normal animals.
* AnxietyDreams: Aang, of course.
* ArmorPiercingQuestion: Parodied.
-->'''Dream!Ozai''': Really? How do you plan on doing that when [[NotWearingPantsDream you're not even wearing pants]]?
* AudibleSharpness: Momo's sword makes this noise.
* BeQuietNudge: When Aang demands more practice and asks Katara to [[HitMeDammit hit him]], she refuses. Then Toph is about to volunteer until Sokka gives her a nudge.
* BigDamnKiss: Subverted. Aang finally tells Katara that he loves her and kisses her, thus letting her kiss him back. But as they get ready to make out some more...Katara's voice asks Aang what he was doing, and he looks up to see her standing there. It was merely a DaydreamSurprise.
* BigNo: Dream!Ozai in Aang's last dream.
* BreatherEpisode: A lighthearted bit of sleep deprivation comedy before the very dramatic ''Day of Black Sun''.
* TheCameo: Guru Pahtik reappears as one of Aang's hallucinations, with six arms, and singing about chakras.
* CatapultNightmare: Aang, when waking from his last nightmare, complete with scream.
* ChekhovsGun: The content of the war meeting go unrevealed for this episode, though whatever it was prompted Zuko to ''finally'' make a HeelRealization. The audience finally finds out what went on in the finale, and boy howdy is it a doozy.
* DavidVsGoliath: Aang hallucinates a battle between Momo the small lemur and Appa the giant bison.
* DaydreamSurprise: Sorry, Kataang fans, gonna have to wait a little longer for the real deal...
* DoesNotLikeShoes: All (current) members of Team Avatar spend the entire episode barefoot.
** Note that the episode spans 4 days, and Aang is the only one that puts on any kind of footwear (his Fire Nation boots) - but he is only seen wearing boots in the opening and closing scenes. All other times he is barefoot for 4 consecutive days like the rest of his friends.
* ExhaustedEyeBags: Aang develops them due to his sleep deprivation.
* {{Fangirl}}: Not surprisingly, Zuko now has in-universe ones trying to get his attention (and possibly other things) when he steps outside the palace. One of these manages to get close, before being dragged off by the guards.
* FreudianCouch: There's a scene where Aang is lying in the grass with his head rested on a sheep and Sokka talking to him like a shrink.
* FunnyBackgroundEvent: When the Gaang makes Aang a bed for him to sleep on, there are some naked koala-sheep next to Sokka.
* GetAHoldOfYourselfMan:
-->'''Katara:''' Aang, I know you're trying to help, but you ''really'' need to get a ''grip.''
* GettingCrapPastTheRadar:
** Nightmares, funny stuff, Kataang ShipTease, hallucinations... hold on, did Zuko spend the night on Mai's couch?
** Mai suggesting ways for Zuko to relieve stress, like... ordering servants around, or taking a palanquin ride.
* GrapesOfLuxury: The Fire Lord has them in Aang's first nightmare.
* InnocuouslyImportantEpisode: The A-plot is Aang having a [[MushroomSamba Sleep Deprivation Samba]] due to anxiety over the coming invasion causing nightmares. The B-plot focuses on Zuko and Mai [[ShipTease cuddling adorably]]... and Zuko attending an offscreen war meeting wherein something happens that will have a large effect on the finale, and which provokes Zuko's HeelRealization.
* TheInsomniac: Aang, and the lack of sleep makes him crazy.
* ALoadOfBull: Aang hallucinates that Appa stands on his hind legs, tells Aang that he needs to take care of himself, and then dons samurai gear, wields three swords, and fights Momo.
* MoodWhiplash: While most of Aang's nightmares are played as comedy, some of them are actually pretty dang frightening. Not to mention the snapback after the aforementioned Kataang Ship Tease.
* NotWearingPantsDream: Aang's most humiliating nightmare. In his final dream, he turns it around on Dream!Ozai.
* NoYou: In Aang's final Ozai dream, the giant Ozai figure tries to tell Aang he isn't wearing pants (again), but Aang turns it on him and says that Ozai's the one not wearing pants, much to his horror.
-->'''Dream!Ozai''': My royal parts are showing!
* PottyEmergency: How Aang predicts Toph drinking water would bring about a loss in their battle in one of his dreams.
* RealDreamsAreWeirder: All of Aang's dreams, as well as his hallucinations. There's such things as Ozai the giant VillainousGlutton, Aang as an anime ShoutOut, giant eyes opening up in the air, [[NotWearingPantsDream Aang suddenly not wearing pants]], Ozai taunting Aang about missing his math test (causing Aang to fall into a giant abacus), Momo being a giant attempting to grab Aang and Appa, Toph not having eyes, there being a random ocean under the Fire Lord's palace, Appa and Momo talking, Appa and Momo swordfighting while sheep cheer them on, and a six-armed Guru Pathik sitting on a cloud and singing about how everyone loves chakras, not to mention the lines of rocks that act like snakes.
* RecurringDreams: Aang is repeatedly dreaming of facing the Fire Lord and failing to defeat him.
* RoadTripAcrossTheStreet: Zuko takes a palanquin to Mai's house, which is just across the street from the palace. Granted, he tried to be nonchalant and just walk over, but his servants insisted otherwise.
* ShipTease: Aang to Katara - "Baby, you're my forever girl."
* ShoutOut:
** Sokka refers to Fire Lord Ozai as "the baddest man on the planet", which was the tagline for Mike Tyson during his prime.
** The three get-ups Aang wears in his Fire Lord dreams are homages to ''Anime/DragonBallZ'', ''Manga/{{Trigun}}'', and wuxia films.
* TooImportantToWalk: The Fire Nation Royals. Leads to a RoadTripAcrossTheStreet for Zuko.
