One day, he hear from an old priest that the only link between real world and the dream is the Moon. He spent another two years camping onto the highest mountain and reached where the Moon is. Afterward, he signed a contract with the Moon for going back to the reality. The cost is that he has to work for Moon rest of his life. Therefore, he became a postman who is responsible for delivering the dreams to thousands of millions of human being every night.
