''Dreamcatcher'' is a 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 and film provide 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.
* AffablyEvil: Mr. Gray
* 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 ''{{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''.
* EvilBrit: Mr. Gray speaks with a British accent in the film.
* EvilDetectingDog: The animals are seen fleeing in mass migration.
* TheExtremistWasRight: [[spoiler:Kurtz. Doesn't make him any more likable, though.]]
* FaceFullOfAlienWingWong: Mr. Gray's head explodes, infecting Jonesy with hundreds of alien spores and transferring Mr. Gray's consciousness into him.
* {{Fartillery}}: One of the signs that you're infected with one of the shit-weasels.
* GeneralRipper: Kurtz.
* GoingNative: Jonsey tempts Mr. Grey with this several times after seeing how much he enjoys human senses and emotions. Mr. Grey, for his part, seriously considers it several times, but cannot bring himself to go againsts his species' HiveMind. [[spoiler: Just before he is killed by Jonsey, Mr. Grey Laments that he should have accepted Jonsey's offer.]]
* GroinAttack: This is how one character dies in the novel (it happens to a different character in the film version).
* TheHeart: Duddits
* HumansAreSpecial: Mr. Grey 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. Grey quickly realizes this, as he is tempted several times (and nearly accepts) by Jonsey 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.
* NobodyPoops: Subverted horribly.
* OmnicidalManiac: Mr. Gray plans on infecting the entire world.
* OneWingedAngel: In the film, both Mr. Gray and [[spoiler:Duddits]] are able to transform into monstrous creatures a their 'final form'.
* PuppeteerParasite: Mr. Gray to Jonesy.
* RaceLift: Kurtz is played by MorganFreeman in the film.
* 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. Grey, in Jonsey's body becomes this, his race of "sentient mushrooms" having never experience human emotions and senses like taste and anger. It takes a dark turn when Mr. Grey 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 apparenty 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).
** [[TheRollingStones Sympathy For The Devil]] is Kurtz's anthem.
** Possibly unintentional, but the name Mr. Gray seems like a reference to {{Literature/It}}, who's main alias was Bob Gray. It seems the film version further lampshades it by having Jonesy talk in a British Accent whenever Mr. Gray possesses him, as It was played by Creator/TimCurry.
* SpockSpeak: Mr. Grey at first. He loses it and speaks more naturally as time goes by and he experiences more of Jonsey's emotions.
* TrademarkFavoriteFood: Mr. Gray loves BACON.
* UnexplainedAccent: In the movie, Jonesy speaks with a British accent whenever Mr. Gray is controlling him for some strange reason.
* VaginaDentata: The mouths of the "shit-weasels" in the film give this impression; as a whole they look something like a lamprey from hell.
* 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.
