We all dream although we remember only a few of our dreams. Some people train themselves to remember
their dreams. As soon as they wake up, they record what their dreams were about.
Scientists believe that we have different kinds of sleep. One kind is called R.E.M. R.E.W. stands for rapid
eye movement. During this kind of sleep our eyes move quickly, even though they are closed. Although we are
asleep, there is a lot of brain activities. We probably have dreams at this time.
Sometimes people talk in their sleep. In these dreams the dreamer is usually unhappy or worried about
something. The worst of the dreams are so frightening that we call them nightmares. In a nightmare we often
dream that we are being closed or that we are trapped in some way.
Scientists or others have written books about the meanings of dreams. The most famous of these scientists
was Sigmund Freud who wrote a hundred years ago. He suggested different meanings to certain kinds of
dreams. It is possible, however, that every dream has a special meaning only for the person who dreams it,
and that this dream about something in that person's life.
