Delusional patient Zuo Yuanxin has a fellow patient named Ji Ji Nian who is suffering from delusional disorder. After Zuo Yuanxin had a strange dream, some changes occurred in the space they were in. Monsters they had never seen appeared, and mysterious supernatural events also occurred from time to time. Except for them, no one else could see any so-called changes. Or is it true that what the madman saw is real, or that it doesn't exist and is just their fantasy. But Zuo Yuanxin's little patient Ji Qinian did turn into a vegetative state because of the monster. To find him, Zuo Yuanxin must enter the dreamland. But Ji Ji Nian in the dream didn't seem to remember him, and he didn't seem to be suffering from delusions of persecution, but this was indeed Ji Ji Nian. In order to seek the truth and to get along with his former patient again day and night, he became his partner. It turned out that everything in the past, including the original Ji Ji Nian, was all his fantasy, and the real Ji Ji Nian was just a vegetable.
