David dreams about a city with streets. He also dreams about boats, lights, carts without horses, and shiny fish-shaped things in the sky. He has never seen any of these things before, yet he is dreaming about them.
David's sister told him not to tell anyone about the dreams. People didn't like anything odd or out of the ordinary.
David Notices a girl watching him as he slides down some sand dunes.
David invites the girl named Sophie to slide down with him.
Sophie gets her foot stuck in a hole while sliding down and they begin to panic.
Sophie's foot is wedged between two stones, and David suggests they take her shoe off. However Sophie doesn't want that to happen.
