A dream is a story that a person watches or appears to take part in during sleep. Dream events are imaginary, but they are related to real experiences in the dreamer's life. Everyone dreams, but some people never recall dreaming. Others remember only little about a dream. Dreams are very easily forgotten, but are connected to the dreamer. People all over the world sleep at night, and dream different, unique images. They spend 1/3 of their lives asleep, which averages about 50,000 hours of dreaming.
