    "Dreams may be more important than sleep. We all need to dream," some scientists say.

    Dreams take up about one quarter（四分之一）of our sleeping time. People have several dreams each night. Dreams are like short films. They are usually in color. Some dreams are like old films. They come to us over and over again. That may be because the dreamer is worrying about something. Dreaming may be a way of trying to find an answer.

    Some people get new ideas about their work from dreams. They may think about their work all day. These ideas can carry over into dreams.

    Too many dreams can be harmful(伤害的).The more we sleep, the longer we dream. The mind is hard at work when we dream. That is why we may have a long sleep but we still wake up tired.
