"A young man, Mukoda, checks himself in to the hospital complaining that his dreams are getting longer and longer; at first his dreams would cover the space of a day, then a week, a month and so on. At first his doctor doesn't take his claims seriously, but when the patient begins to manifest signs of physical mutation and forget the previous day's events, he takes a special interest in the case."
