Another sleepwalker, this time a young man, comes to the psychologist's office one day. The young psychologist is shocked to learn that the young man is a habitual sleepwalker. He also learns that the sleeping man has killed a stray dog. The psychologist is not surprised at all, for he has been studying sleepwalking for the past year. He tells the young psychologist about another young man he met when he was a trainee. This young man was a 28-year-old man, curly haired, who worked in a bicycle factory. He asked the psychologist to talk to him about his situation, and the psychologist agreed to do so. After the psychologist finished talking to him, the old man asked him to watch a video on his own, and he did so. The old man left, and when the psychologist came back, he was shocked to find out that the man had been sleeping in his apartment the night before, and that he had gone to the doorway of the building to get a cigarette. He was shocked, too, because he was not only shocked at the strange behavior of the man, but also at the cause of it.
