There was a son named Anton. He dreamed that a girl placed a handkerchief over his face. He woke up but he saw no one. Anton told his mother what he had dreamed. His mother said, "Anton, you've dreamed of something enchanted."

"Anton," his mother said, "you dream of a girl who lives with her father in the tower of the moon."
