Did you dream last night? What did you dream about? You might not remember your dreams, but people usually dream four to six times a night. Dreams can be short, only about ten minutes, or can continue for an hour or more. People dream in color.
    At times, we all remember a dream. In our dreams, we might take a trip or look back at our childhood. We might run away from a tiger or see a terrible accident. Someone we love might die.
    What is the meaning of these dreams? Many psychologists believe that dreams are "night work". They help us look at situations and fears in our daily lives. In our dreams, we face problems and try to solve them. We look at our fears. We try out different personalities; at times we might be aggressive and talkative and at other times we might be frightened and shy.
    We often dream in symbols. Symbols are pictures that stand for or mean something else. A king and a queen might represent our parents. Small animals might stand for children. A long journey might mean we are worried about death or the death of someone in our family. If we are crossing a river, it might mean that we are at an important decision or time in our lives. If we get across the river in the dream, we believe we will be successful. If we do not make it across, we are afraid of failure.
    We can have the same dream over and over. The dream may always be the same or it might have different endings. Our minds are working and playing, making movies about our lives.
