Have you ever wondered how many secrets are hidden behind such a simple act as falling asleep in a cozy bed after a working or school day? In an effort to solve the riddle of sleep, Dr. Guy Leschziner embarks on 14 amazing journeys with his patients. All of them are ordinary people, but with unusual abilities: one of them has 25 hours a day, the other, falling asleep, feels bees buzzing under his skin, and the third is able to sleep at all, not completely, but partially, turning on and off different lobes of the brain depending on the life situation. Together with them, you will follow the path of self-knowledge and secrets that our own brain still hides from us.
