''Dreamscape'' is a ScienceFiction film directed by Joseph Rubin (''Film/TheForgotten'', ''Film/SleepingWithTheEnemy''), starring DennisQuaid (''Film/VantagePoint''). The film was released in the United States in 1984 by 20th Century Fox. The plot is loosely based on the novel ''TheDreamMaster'' by RogerZelazny.

Alex Gardner (Quaid) is a man with special talents [[PsychicPowers psychic talents]], to be exact. While participating in ground-breaking studies on the powers of the mind at the age of 19, he suddenly quit and attempted to disappear, from then on only using his abilities for petty personal gain. Years later, his extraordinary "good luck" both at the race track and with the ladies has drawn the attention of unsavory eyes... and now he and his talents are in high demand by everyone from local gangsters to shady government agents.

When Alex is contacted by the college professor that performed the studies on him years ago, Alex agrees to hear him out, both for old times sake and to have a place to momentarily hide from everyone who wants a piece of him. When the professor explains what he's working on -- a project that will allow those with psychic abilities to enter the dreams of others -- Alex is intrigued, and with a little [[{{Blackmail}} "convincing"]] agrees to help out. With the professor's assistance, Alex is quickly able to master the ability of entering, observing, and even modifying people's dreams. At first he feels exhilarated, intoxicated by the freedom and power that come along with his new-found ability. However, things are not quite what they seem... inside the Dreamscape, Alex finds that he is facing progressively more dangerous nightmares, and outside he must deal with the schemes of not only a [[TheRival rival psychic]], but also of the shadowy machinations of the people who are truly behind the Dreamscape project.

!!This film provides examples of the following:

* AfterTheEnd: The President's nightmares take place in the flaming ruins of a nuked city.
* AnAxeToGrind: Buddy grabs an axe [[OffWithHisHead to decapitate]] the Snake Man during his nightmare.
* BeatStillMyHeart: After Tommy Ray rips a security guard's heart out of his chest.
* DangerousWindows: The Snake Man breaks in through a window to grab Buddy.
%%* DreamSpying
* DreamWeaver: Alex and Tommy.
* EroticDream: Inverted/Invoked. DreamWeaver Alex uses his powers to enter Jane's dream to make out with her, without telling her it's not just a random dream she's having about him. She quickly forgives him when she finds out, but this seems strange since it could easily be construed as rape by fraud (he deluded her on purpose and she didn't give consent).
* AGodAmI: Tommy Ray makes this boast:
-->'''Tommy Ray:''' In this world, Alex, you're nothing. And me, I'm God.
* HalfHumanHybrid: The Snake Man.
* IKnowYoureWatchingMe: It becomes clear to the scientists secretly observing Alex through a two-way mirror that he knows what's going on when he writes "Let's get on with it" on his side of the mirror in pen... especially since he writes the letters backwards so that those on the other side can read it.
* InfantImmortality: Played straight with Buddy; in the President's dream, [[spoiler: the kids trapped in the ruins aren't just dead, but ''mutilated'' to BodyHorror levels]].
* MindOverMatter: Minor telekinesis is among the range of PsychicPowers Alex displays over the course of the film, and we see a still movie slide of him levitating a small metal, ball bearing. If viewers were expecting him to use this at any point in the film to save himself from a dangerous situation, they will be disappointed because the movie focuses on his ability to enter dream instead. It never becomes the ChekhovsGun, and stays an InformedAbility.
* MinorCrimeRevealsMajorPlot: When a subject is killed in the real world by dying in the Dreamscape, Alex starts to realize he's in over his head... what he doesn't know is that [[spoiler: the government is training his rival, Glatman, to assassinate people in their sleep]].
* MonumentalDamageResistance: During a recurring nightmare the President of the United States is experiencing, a partially destroyed Capitol building is seen in the ruins of Washington, D.C., after it was ravaged by nuclear war.
* NeverSleepAgain: Tommy Ray Glatman assassinates people by using his psychic abilities to enter their dreams and kill their dream selves.
* NotIfTheyEnjoyedItRationalization: Alex's rationalization for covertly inserting himself into Jane's dreams to make her think she was having a sex fantasy about him, rather than making out with the real life person. The fact that she enjoyed herself doesn't negate the fact that he just basically raped her (MindRape?), as she was in no position to give informed consent.
* OrWasItADream: The train conductor that appeared in Jane's dream later appears in the real world.
* OurPresidentsAreDifferent: President Target, at least where dreams are concerned; in the real world he's more President Iron.
* PartialTransformation: Tommy Ray scales back his snake transformation when he is confronted by the image of his dead father.
* PistolWhipping: Alex pistol whips a federal agent while re-infiltrating the project facility.
* RedEyesTakeWarning: The SavageWolves chasing Alex and the President in the final dream sequence have red GlowingEyes.
* ReptilesAreAbhorrent: The nightmares of a young boy Alex is trying to help take the shape of a half-man/half-snake creature. One of the villains also later assumes this form while in the dream world.
* SavageWolves: Alex and President must outrun couple of wolves with red GlowingEyes along with ScaledUp Tommy Ray.
* ShapeshifterGuiltTrip: Alex turns himself into Tommy Ray's dead father to distract him from killing the President.
* VillainBall: Tommy had ample opportunity to kill the President in his dream, but he just had to take the time to mess with his and Alex's heads.
* YourMindMakesItReal: Not only is Alex capable of causing himself severe mental damage while in the Dreamscape, but both the subjects and the psychics helping them can be killed in real life if they die while dreaming.
* YourWorstNightmare: What Alex tries to help his subjects overcome.
