Ben Dobbs, an American college student in 1988, finds himself tormented by a series of increasingly surreal and disturbing nightmares. The dreams pile up with recurring images: a red balloon, a crazed janitor with hook hands, a non-existent younger brother named Ricky, a sensuous woman who routinely exposes her breasts, and, most prominently, a large, fleshy red monster that feels like a cross between a demon and a werewolf. The blend of the familiar and the terrifying blurs the line between sleep and waking life, leaving him shaken and determined to understand what’s happening to him.
Seeking answers, he passes a leaflet describing his most recent dream to his psychology teacher, Professor Noxx, and asks for his guidance. He then attends a session with Julie Oxel, who has been running a dream research experiment. She gives him a sleeping pill and records his dreaming as part of the study, turning his private nightmare into data and insight, or so it seems at first.
That night, he is summoned to the professor’s home for a discussion about the dreams. The professor explains that Ben’s experiences resemble a case from twenty years earlier involving D.F. White, an otherwise ordinary young man who began having vivid, violent nightmares before slipping into a coma and dying. The revelation casts a chilling light on Ben’s experiences, hinting at a pattern that transcends one person and one time.
Together, they search for answers in the college library, where Ben glimpses the ghost of D.F. White. The ethereal warning is stark: “It will take everyone he turns to for help and “hide them” within his dreams.” It’s a foreboding omen that foreshadows a danger spreading beyond the confines of sleep. Moments later, the nightmare intrudes in the real world as the monster from his dreams violently brutalizes the professor, forcing Ben to flee in terror.
The next day, Ben returns to the library and retrieves the same book they had been reading, only to discover that the pages detailing White’s case have vanished as if they never existed. He then confides in Eric Baxter, Noxx’s other assistant, describing a recurring dream location with large concrete trapdoors. Eric recognizes the place as an old, unused room in the college and escorts Ben there, speculating that the monster might originate from beneath those trapdoors.
Meanwhile, Julie Oxel contacts Eric to report that Noxx’s phone line has been disconnected and his name erased from the college register. Ben also learns that Noxx’s entire house has vanished, amplifying the sense that something malevolent is erasing evidence and reaching beyond ordinary reality.
That night, after reviewing a tampered recording of Ben’s dream, Eric and Julie head home. Eric examines a set of animal-like teeth he had found earlier in the trapdoor room. As they read through a transcript of Ben’s dreams, both men share a vision of Julie in danger, and they hurry to her house, only to find she has been decapitated.
Unable to return to his own home, Ben seeks refuge with Eric, but finds Eric’s house in disarray—Ben’s leaflet is shredded, and the mysterious teeth have vanished. Ben concludes that the monster is actively destroying any trace of its existence and will now target both him and Eric.
Having recovered one of the missing pages about D.F. White, Ben devises a plan: lure the monster back beneath the trapdoors using the page, with the hope of banishing it from reality. That night, he and Eric break into the college and rig a crane mechanism to hold the trapdoors open. The plan goes horribly wrong when the monster kills Eric, but Ben presses on. In a final, desperate move, he uses the recovered page to bait the creature into the pit beneath the trapdoors and releases the mechanism, slamming the trapdoors shut—leaving his own fate unresolved and hanging in the balance of a nightmare that refuses to end.
