''Dreamcatcher'' is a 2001 novel written by Creator/StephenKing.

Gary Ambrose "Jonesy" Jones, Pete Moore, Joe "Beaver" Clarendon and Henry Devlin are four [[TrueCompanions lifelong friends]]. As kids, they saved Douglas "Duddits" Cavell, a boy with Down syndrome, from a group of bullies.

As adults, they go on an annual hunting trip where they come across a delirious stranger talking about lights in the sky. It becomes revealed that he's infected by an alien parasite. The army arrives led by the psychotic Colonel Abraham Kurtz who puts the area under quarantine. As the infection develops, the plot thickens.

Was made into a film directed by Creator/LawrenceKasdan in 2003.

!!The novel provide examples of:

* TheAlcoholic: Although he attempts to deny it, Pete is definitely one.
%%* AlienInvasion
* AnyoneCanDie: [[spoiler: Beaver and Pete both die in the first half of the story. By the end of the book, Jonesy and Henry are the only surviving characters.]]
* BattleInTheCenterOfTheMind: Between Mr. Gray and Jonesy.
* BodyHorror: The aliens are referred to as "shit-weasels". Guess where they come out of infected people. Later on, [[spoiler:Kurtz]] is infected by the Byrum, and it grows on his face like a mold infestation that's squeezing and cracking his skull.
* CanonWelding: Takes place in the fictional town of Derry, Maine, the site of previous King novels ''Literature/{{IT}}'' and ''Literature/{{Insomnia}}''. At one point a character comes across a memorial written by the Loser's Club from ''IT''. Scrawled on in graffiti is "PENNYWISE LIVES''.
* {{Deconstruction}}: Of AlienInvasion fiction in general. King set out to rationalize a species being advanced enough to travel the cosmos while still desiring to invade and conquer pre-spaceflight planets. He came up with the Byrus; (semi)-intelligent parasites spreading throughout the universe using whatever tools available. The ones in the book were just lucky enough to have stolen interstellar craft from a far less belligerent species.
* EvilDetectingDog: The animals are seen fleeing in mass migration.
* TheExtremistWasRight: [[spoiler:Kurtz, to an extent. Doesn't make him any more likable, though, especially when he goes too far in treating all people infected with the Ripley as though they're doomed when infection is only occasionally fatal.]]
* FaceFullOfAlienWingWong: Mr. Gray's head explodes, infecting Jonesy with hundreds of alien spores and transferring Mr. Gray's consciousness into him.
* FauxAffablyEvil: Mr. Gray is at least initially polite in most interactions.
%%* GeneralRipper: Kurtz.
* GoingNative: Jonesy tempts Mr. Gray with this several times after seeing how much he enjoys human senses and emotions. Mr. Gray, for his part, seriously considers it several times, but cannot bring himself to go against his species' HiveMind. [[spoiler: Just before he is killed by Jonesy, Mr. Gray laments that he should have accepted Jonesy's offer.]]
* GroinAttack: This is how one character dies in the novel.
%%* TheHeart: Duddits
* HumansAreSpecial: Mr. Gray mentions several times how Humans have put up more resistance against them than any of race they have assimilated. [[spoiler: In the end, it is revealed that over half of the human population is naturally immune to the Byrus.]]
* HumanityIsInfectious: Mr. Gray quickly realizes this, as he is tempted several times (and nearly accepts) by Jonesy to abandon his mission to infect the world and simply enjoy experiencing all the human senses and emotions. While he refuses, by the end of the novel he gradually grows, speaks and acts more human.
* InspirationallyDisadvantaged: Duddits is of the Type C variety.
* MeatMoss: A component of the aliens' invasion, spreading gradually across whatever surfaces it can. It's likelier to be fungal in nature, but still has a visceral, fleshy look.
%%* NobodyPoops: Subverted horribly.
* OmnicidalManiac: Mr. Gray plans on infecting the entire world.
* PoliticallyCorrectVillain: Upon hearing that one of his soldiers has referred to TheGrays as "space niggers," Kurtz promptly [[DisproportionateRetribution shoots him in the leg]] and delivers a pious lecture on how that sort of language is against the army's standards of racial sensitivity. Oh, they're [[GuiltFreeExterminationWar going to exterminate the aliens,]] absolutely, but they're going to do it without using that sort of language!
* ThePowerOfFriendship: Childhood friends who have long since gone their separate ways must now come together to defeat the BigBad.
%%* PuppeteerParasite: Mr. Gray to Jonesy.
%%* TheRainman: Duddits.
* TrueCompanions: Jonesy, Henry, Pete, and Beaver are this, along with Duddits.
* SadClown: Beaver turns out to be this, when he tells Jonesy that "he has to be happy for the rest of them".
* SenseFreak: Mr. Gray, in Jonsey's body becomes this, his race of "sentient mushrooms" having never experienced human emotions and senses like taste and anger. It takes a dark turn when Mr. Gray realizes how much he enjoys killing people.
* ShootTheFuelTank: How Henry blows up one of the two Hummers to kill the final shit-weasel. Double-subverted, since at first nothing happens and Henry even laments that in real life this kind of thing apparently doesn't work the way it does in Hollywood movies, but then fuel tank explodes after all.
* ShoutOut:
** Kurtz is named after the character ''Film/ApocalypseNow'' and ''Literature/HeartOfDarkness''. {{Lampshaded}} with a comment that it's probably not his real name and probably something that he decided to call himself.
-->Perlmutter had read ''Heart of Darkness'', had seen ''Apocalypse Now'', and had on many occasions thought that the name Kurtz was simply a little too convenient. He would have bet a hundred dollars (a great sum for a non-wagering artistic fellow such as himself) that it wasnít the bossís real name-that the bossís real name was Arthur Holsapple or Dagwood Elgart, maybe even Paddy Maloney. Kurtz? Unlikely. It was almost surely an affectation, as much a prop as George Pattonís pearl-handled .45.
** The government nickname for the alien fungus is "The Ripley" after Creator/SigourneyWeaver's character from the ''Film/{{Alien}}'' movies.
*** Jonesy is also the name of Ripley's cat from ''Film/{{Alien}}''.
** And Duddits's love for ''Franchise/ScoobyDoo'' (despite not being able to pronounce the theme song's lyrics).
** "[[Music/TheRollingStones Sympathy for the Devil]]" is Kurtz's anthem.
* SpockSpeak: Mr. Gray at first. He loses it and speaks more naturally as time goes by and he experiences more of Jonesy's emotions.
* TrademarkFavoriteFood: Mr. Gray loves BACON.
* VorpalPillow: How [[spoiler: Mr. Gray]] is killed.
* WaterSourceTampering: Mr. Gray's plan of spreading the alien infection.
* YourHeadASplode: Mr. Gray's head explodes early on to infect Jonesy with his spores. Later on, [[spoiler: Kurtz]]'s head is blown off with a gun.

!!The film version has examples of:

* AdaptationDyeJob: In the book the minor character Trish had brown hair; in the film she has blonde hair.
* AdaptationNameChange: The film changes Kurtz to Curtis because of the ''Film/ApocalypseNow''[=/=]''Literature/HeartOfDarkness'' reference. King asked them to change it to a name that still sounded similar to Kurtz.
* AdaptationalHeroism: Well, not heroism per se, but Henry was kind of a jerk in the book (of the intellectual persuasion), but not so much in the film.
* EvilBrit: Mr. Gray speaks with a British accent.
* GroinAttack: This is how one character dies in the film.
* IAmAMonster: Colonel Curtis' pre-asskicking speech during the Apache gunship attack.
-->"Now if anyone's thinking: ''Why those poor, helpless little folk, all naked and unarmed outside their crashed intergalatica winnebago. What kind of monster, could hear that heartbreak and go in just the same?'' I'm that dog! I'm that monster! These little mothers are as harmless as a fox in a henhouse! And I'm here to kick some ass!"
* INeverToldYouMyName: A woman who lost her keys meets Pete and he says her name without her telling him. He then helps her find her keys, demonstrating knowledge of her car, her prior movements and the exact place she lost her keys. He then asks her on a date at a restaurant which he says is located "right on [her] way back". She is understandably creeped out.
* OneWingedAngel: Both Mr. Gray and [[spoiler:Duddits]] are able to transform into monstrous creatures as their 'final form'.
* RaceLift: The white Kurtz from the novel is played by Creator/MorganFreeman.
* {{Telepathy}}: Weaponised , as the gunship crews hear the aliens pleading for them not to. Curtis responds with a RousingSpeech.
* UnexplainedAccent: Jonesy speaks with a British accent whenever Mr. Gray is controlling him, for some strange reason.
* VaginaDentata: The mouths of the "shit-weasels" give this impression; as a whole they look something like a lamprey from hell.
