He ran off as fast as he could, but they followed him. He reached a place where he saw two roads in front of him, one to the right and the other to the left. Which road should he take He heard the two men behind him, getting nearer, and at the same time he heard a voice in his ear. It told him to go to the right, and he did so. He ran on and soon came to a small hotel. He was received there kindly and given a room, and he was saved from the two men. That was the dream.
