A horror story by Junji Ito. An admitted patient enters the hospital having realistic nightmares that seem to span years to decades. They increase in length exponentially until he begins to lose hair and his eyes gray, unable to discern reality from his dreams. At some point, he reaches an eternal dream in which his physical body decays and dries into a husk. There is a crystal in his brain that the doctor gives to other patients to allow them to live ‘longer’.
