''[[http://www.fanfiction.net/s/2636963/1/Harry_Potter_and_the_Nightmares_of_Futures_Past Harry Potter and the Nightmares of Futures Past]]'' is a PeggySue fic written by [[IHaveManyNames S'Tar'Kan / Viridian /]] [[FanNickname Evil Author Lord]], who also authored the equally-excellent {{Naruto}} AU ''FanFic/{{Team 8}}''. The two stories are regarded by some as sister fics, as they both have large followings and are highly-regarded in each of their respective fandoms.

The story opens with an adult Harry finally defeating Voldemort after fighting him and his Death Eaters for about thirteen years. The victory is extremely hollow, however; the war has directly or indirectly claimed the lives of virtually every named character in the series and Harry has lost everyone he ever loved and then some. As a potentially fatal case of depression begins to settle in, however, Harry uncovers theoretical texts in the ruins of Hogwarts that suggest a means by which to travel backwards in time.

With literally nothing left to lose, Harry gambles his life on a second chance and hits the jackpot when his spirit merges with his younger self partway through the summer before his first year at Hogwarts. In classic PeggySue fashion, "young" Harry then begins subtly altering the timeline to make things better... with mixed results.

The story is regarded by many as a textbook example of how to do a PeggySue fic; Harry's efforts to change the future create as many problems as they solve, for one thing, and the multiple layers of conflict in the story prevent Harry's advanced skills and greater power from making things too easy for him.

Story has not been abandoned, though WordOfGod states that updates will likely be slow, due to personal issues, both health- and job-related. After about a three year hiatus, chapter 39 was finally released on October 19, 2012.

Viridian maintains a blog and a forum where he posts occasional word count updates.
[[ViridianDreamsQuests Viridian Dreams Quests]] are run out of his forum.

!!This fanfiction series contains examples of:

* AbusiveParents: The Dursleys of course, but [[spoiler:Vernon more so than usual]] thanks to the ButterflyOfDoom.
* AdultsAreUseless: Harry seems to have this opinion firmly in mind given [[spoiler: what he saw unfolding in his future]]. However even when an adult figure does do something right, Harry is still prone to reluctantly awarding them a point in his mind and bitterly remarking to himself what a wonder it was.
* AntiVillain: Dumbledore. In a refreshing twist, the Big D isn't portrayed as a Machiavellian Chessmaster or a cacklingly evil MagnificentBastard, but as a fundamentally good person with the unfortunate flaw of thinking he knows what's best for people. He's not even a villain, really, more like a hero who could [[NiceJobBreakingItHero really mess things up if he tries to do what he believes is the right thing]]. Now Snape, on the other hand...
* ArcWords: "Broken and battered body" comes up a lot whenever Harry thinks of the future.
* ADayInTheLimelight: A lot of side characters from the original series get more attention, some even get half a chapter told from their perspective.
* BadFuture: Hoo boy.
* BigDamnHeroes: In Chapter 39, Dumbledore's Patronus and Fawkes.
* BoringInvincibleHero: [[JustifiedTrope Justified]] in that Harry is far more experienced from surviving the BadFuture, but keeps getting blindsided by the ButterflyOfDoom and has to check himself every now and then to keep things from getting worse.
** Some of these victories also have repercussions in the story, for example when Harry goes to fight Quirrel!Mort on his own, his friends are disappointed he left them out, and the important bonding moment of the first book is missed.
* BerserkButton: [[spoiler:In the BadFuture, captives of the Death Eaters could shout '''CONSTANT VIGILANCE!''' for an instant kill thanks to Moody's DyingMomentOfAwesome.]]
* ButterflyOfDoom: A refreshing change in the PeggySue genre, as Harry's efforts to rewrite history frequently have totally unintended consequences, both good and bad.
* CallingTheOldManOut:
** Arthur Weasley does this to Dumbledore [[spoiler:after the Dursleys' abuse of Harry is discovered.]]
** [[spoiler:Neville]] calls out [[spoiler:Augusta]] for interfering in his developing relationship with Luna.
* CareBearStare: Harry uses this on Voldemort in the very first chapter. It even includes the associated light show.
* ChessMaster: Harry. Amusingly, he's rubbish at actual chess.
* ChekhovsGun / DreamingOfThingsToCome: Chapter 29's reference [[spoiler:to a magical core exploding]] in nightmare form is ominous in the extreme. The accuracy of Harry's previous nightmares doesn't help either.
* ContrivedClumsiness: Harry pratfalls to break Ron and Neville's wands so he can get them replaced.
* DeadpanSnarker: Harry, even more so than in canon.
* DeconstructionFic
* DrunkenBoxing: Luna picks this up from watching television at a friend's house once. One of the many reasons she's CrazyAwesome.
* EskimosArentReal: Ron pokes fun at Luna Lovegood for having an "imaginary creature" as her Patronus. Luna's patronus was a duck-billed platypus. When Hermione tells Ron that the duck-billed platypus is a real animal, he flatly refuses to believe her.
* EverythingsBetterWithPlatypi: Luna's Patronus.
* FinishingEachOthersSentences: Fred and George constantly. It's hard to find a line that they don't split.
* FromACertainPointOfView:
** Harry's ''modus operandi''. He ''did'' happen to overhear Draco boasting about a special room in his house full of illegal items, it just so happens that he did so in an alternate timeline.
** The Sorting Hat learns of Harry's secret the moment it's placed on his head, and decides to keep what it knows of Harry in confidence. When later asked if some "invading mental presences" were in Harry's mind, it coyly answered:
--->'''Sorting Hat:''' "Oh no, no invaders at all. Nothing between his ears but Harry James Potter."
* GlassShatteringSound: Harry does a version of this when he uses magic to amplify his voice during Chapter 39. The windows facing him in ''Hogsmeade'' cracked.
* TheGlomp: Ginny glomps Harry during the CrowningMomentOfHeartwarming.
* HeroicSacrifice: While it became a recurrent happening in the Bad future, mentions must go to:
** [[spoiler:Ron, who Polyjuiced himself as Harry during a trap and ended shredded/tortured]];
** [[spoiler:Shacklebolt facing Voldemort singlehandedly to gain time for the Order]];
** [[spoiler:Above all, Mad Eye Moody, who executed all the Death Eaters in Azkaban and rallied the guards to a last stand against Voldemort's forces, to the point that his catchphrase is considered taboo from then on]].
* HypocriticalHumour
-->"What's not hard?" Ginny asked. \\
"Talking to you when you're mad about something, without getting hexed," Ron said bluntly. \\
"Ron, I do not go around -- how could you say such a thing?" she asked, fuming, reaching for her wand.
* InnocentInnuendo: While talking about playing Wizard's Chess:
-->'''Ron:''' Hermione went thirty five minutes once, but she always took a while to make her moves.
* IJustShotMarvinInTheFace: Mr. Weasley proves the inefficiency of a magic gun to Harry... by putting the gun to his head and pulling the trigger. The worst part? ''It was loaded and Mr. Weasley wasn't pulling the trigger with enough force''. It took Harry several minutes to stop shaking.
* [[IWantMyBelovedToBeHappy I Want My Friends To Be Happy]]: Harry is painfully aware [[spoiler:for the first two years of the loop]] that his manipulations of his friends for the greater good makes him no better than Dumbledore, but he's prepared to accept their hatred if it means they'll survive the coming war.
** Then he ends up telling them. [[CrowningMomentOfHeartWarming He shouldn't have worried.]]
* KilledOffForReal: [[spoiler:Melissa Bulstrode]]
* TheLostLenore: [[spoiler: Ginny became this to Harry in the original timeline. The older Ginny slowly starts to slip away in favor of her current self, but occasionally it still hits him (like when a boggart becomes her corpse).]]
* ManipulativeBastard: Harry again, though without the bastard part (although Harry does wonder sometimes).
* MindRape: Both played straight and subverted. [[spoiler:Both Snape and Dumbledore use Legilimency to read students' minds, although Dumbledore is ''much'' more reserved about it than Snape.]] Once Harry catches on to this, [[spoiler:he begins training the Weasleys, Hermione, Neville, and Luna in Occlumency, eventually getting everyone good enough that they can't be read, which drives Snape berserk.]]
* PhraseCatcher: People have a tendency to refer to Snape as "that greasy git".
* PreAssKickingOneLiner: "Let's test out mum's handiwork, shall we?"
* ProtagonistCenteredMorality: Harry is very adamant about certain people being bad and/or wrong, and is quickly able to sway people into thinking along the same lines as himself. Understandable when it comes to someone like Professor Snape, since he's both a suspicious and deeply unlikable man, but not so much when it comes to [[spoiler: Professor Dumbledore. Harry only has to throw out a few snotty rants and adults who have known him for all of a couple of years are suddenly ready to take his side over Dumbledore's, who they've known and fought alongside for ''decades''.]]
** Only after the man tried to send Harry back to the family that nearly beat him to death causing people to question his judgement.
* PsychicStatic: Luna's mind is a natural case of that.
* PyrrhicVictory: The premise.
* RightBehindMe: Draco really should have known better than to call Professor [=McGonagall=] an "old hag" in the middle of a meeting of the club she sponsored.
** A new one as of chapter 39. Harry is doing an AffectionateParody of Professor [=McGonagall=] as the Professor herself walks in to bring the The Gryffindor Six to the Headmaster's office
* SixStudentClique: The Gryffindor 'Six.
* ShoutOut:
** A fairly subtle one to Gary Gygax in chapter 33.
** To spiderman after Harry [[spoiler: blows up not just a boggart but everything in the room along with it.]]
** {{Literature/Discworld}} at the end of chapter 38.
* SleepCute: Everybody in the Gryffindor Six gets one, all at the same time, in Chapter 22.
* TheSmartGuy: Harry presents the image of a bookworm to help explain any advanced skills he may let slip.
* SpitTake: After Luna makes a rather blunt and nonchalant declaration of how much she likes watching Neville, his response is described thusly:
--> Harry dodged to the side as Neville sacrificed a mouthful of Pumpkin juice to the gods of the spit-take.
* TaughtByTelevision: Leave it to Luna to learn the basics of DrunkenBoxing from watching television.
* TookALevelInBadass:
** The Gryffindor Six, due mostly to Harry starting up the D.A. a few years early in the guise of a dueling club.
** [[spoiler:Neville]] benefits greatly from a few words of encouragement in just the right place.
** [[spoiler:Neville and Ron both get their wands "accidentally" broken by Harry, and replaced with wands that actually work for them.]]
* TrueCompanions: "The Golden Trio" are now "The Gryffindor Six" thanks to the additions of [[spoiler:Luna, Neville, and Ginny]] into the core group.
* WarIsHell: The alternative future war ended with [[spoiler:the virtual destruction of Magical Britain, the death of every single named character, the "helpful" invasion of the Americans, and the high probability of the loss of the masquerade]].
* [[spoiler:WesternTerrorists]]
* WishFulfillment: One of the first things Harry does is to get leverage against the Dursleys, and then he goes on to avoid most of the uncomfortable things Snape originally did in the novels. [[spoiler:This may end up being a subversion, as the much-increased defiance of Snape may turn out to have been a bad choice.]]
** Everything about Snape starts in the first Potions class, where Harry attempts to show Snape he is good at Potions. [[spoiler:Snape doesn't take it well, and despite Harry's efforts Snape ends up hating him even more than in canon.]]
* YouCantFightFate: One of Harry's most pressing concerns. Some events seem determined to happen despite Harry actively attempting to avert them, which keeps the plot from going completely off the rails but also has Harry sweating bullets about his seeming inability to change history.
** Mind you, some of this seems to have been caused deliberately by an "[[TheChessmaster agent-in-place]]", whose mission seems to be making sure certain things happen.
