“Dreams
may be more important than sleep. We all need dreams,” some scientists say.
Dreams
take up about one quarter of our sleeping time. People have a few dreams each
night. Dreams are like short films. They are usually in colour. Some dreams are
like old films. They come to us over and over again. That may be because the
dreamer is thinking 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. Sometimes we wake up with
a good feeling from a dream. But often we can't remember the dream. Dreams can
go away quickly.
Too much
dreaming cannot be good. 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 and still wake
up tired.
