Nagai Yume
Plot. Dr. Kuroda, a celebrated neurosurgeon, expresses severe doubt when a patient named Tetsuro Mukoda is admitted, complaining of increasingly long dreams, although his assistant, Dr. Yamauchi, believes there may be some truth to Mukoda's complaints. Another patient at the hospital, Mami Takeshima, who was admitted for treatment for a benign tumour, begins experiencing a heightened fear of death, and has a harrowing encounter with Mukoda, who wanders the halls at night, too afraid to sleep. Though he continues to believe Mukoda's symptoms are just hallucinations, Dr. Kuroda agrees to admitting him, and decides to study  his symptoms in detail. Using an EEG machine, Kuroda discovers that when Mukoda sleeps, there are brief periods when he enters rapid eye movement sleep, spanning just a few seconds at a time. During this period, his brainwaves become erratic and his eyes thrash about wildly, only to suddenly stop. In that brief moment of REM, he is in the depths of his condition. With each passing night, the perceived length of Mukoda's dreams seem to be increasing, from months, to years, to decades and then to centuries, and often the experiences he suffers while dreaming are extremely unpleasant . Every time he wakes up, Mukoda begins suffering increasingly strong amnesia, often having to be reminded by Kuroda why he was admitted to hospital. Mukoda becomes pale and gaunt over time as his illness worsens. Mukoda continues to suffer from his long dreams, and eventually undergoes extreme mental and physical mutations as his dreams become several millennia long within his mind; it is as if Mukoda is really living the length of time he perceives his dreams are. Eventually believing that Takeshima is his wife from within the dream world, a severely-mutated Mukoda accuses Kuroda of trying to interfere  in their 'relationship' upon waking, and accosts Takeshima. Shoving the doctor aside, Mukoda runs to Mami's room with Kuroda in hot pursuit. Terrified, Mami accuses Mukoda of being death, before Kuroda manages to intervene. Mukoda comes to his senses, and asks "What happens to the man who awakens from an eternal dream?" Mukoda's mutations continue to worsen, and he eventually experiences an eternal dream. With his spirit fleeing his body, Mukoda crumbles away into dust, leaving behind strange red crystals. Shortly afterwards, Takeshima confides to Yamauchi that her fear of death is lessening, but that she too is  starting to experience long dreams. Fearing that there may be a viral component to the illness Mukoda suffered from, Yamauchi consults Kuroda on the matter, who admits that he had been using the crystals on Takeshima in secret, having realised they were the secret to Mukoda's condition. Yamauchi is horrified by this, stating that it desecrates the souls of the dying, but Kuroda reasons that humanity will have no reason to fear death if they have the option of having eternal dreams instead. Film ending. In the television drama, the conclusion of the story continues beyond this point, and  is significantly different to the ending of the story on which it is based. Eventually, Takeshima, experiencing a similar mental breakdown to the one Mukoda experienced, murders a nurse at the hospital, then promptly commits suicide. Yamauchi takes matters into his own hands, and sneaks into Kuroda's office at night to see if he can find any information about the nature of Mukoda and Takeshima's long dreams. He finds a set of video tapes surrounding the case, and then discovers Kuroda's dark secrets. By testing the crystals on Takeshima, Kuroda intends to find a way to enter  the dream world, trying to reunite with the spirit of his deceased lover and former patient, Kana Sakurai, who died from an accidental overdose of phenobarbital administered by Kuroda during her treatment at the hospital, a few years prior to the events of the film. Kuroda, having experienced visions involving Kana throughout the film, has also been surreptitiously administering the chemical crystals on himself. Kuroda suddenly appears in the office, and Yamauchi, horrified by what he has just learned, asks Kuroda just why he would do such a thing. Kuroda reasons that humanity never need fear death again if they  had the option to go into an eternal dream. Disgusted, Yamauchi replies that this would desecrate the spirits of the dying. Kuroda breaks down, and reveals that despite taking the crystals, he is now unable to dream at all. Yamauchi comments on the poetic irony of the situation, and prepares to leave, only for Kuroda to bludgeon him to death with a framed photograph of Kana. After a final encounter with Kana's spirit, who bids him farewell, the Doctor turns around to find that horrifyingly, the whole incident had been captured on a set of cameras. By administering the  crystals to himself, he has now become infected by whatever caused Mukoda and Takeshima's condition. Beset by powerful delusions and hallucinations, Kuroda descends into madness (all documented on the cameras), before suddenly waking up in a hospital bed to find Yamauchi - his death having been just another hallucination - and three other doctors taking notes. Much like how Mukoda had been seen scrawling gibberish onto the walls of his room on the ward, Kuroda had repeatedly written Kana's name on the wall multiple times. After Yamauchi asks if Kuroda is feeling okay, the doctor-turned-patient looks down at  his mutated hands, and begins weeping as he finally goes insane, bearing mutations similar to those Mukoda had displayed.
