     Dreams are expressions of thoughts, feelings and events that pass through our mind while we are sleeping.

Everybody dreams. But only some people remember their dreams. Our dreams often include all the senses-smells, sounds, sights, tastes and things we touch. We dream in colour. Sometimes we dream the same dream over

and over again. These repeated dreams are often unpleasant. They may even be nightmares-bad dreams that

frighten us.

     Early in the twentieth century, two famous scientists developed their personal ideas about dreams.

Austrian psychiatrist (精神病专家) Sigmund Freud published (出版) a book called "The Interpretation of

Dreams" in 1900. Freud believed people often dream about things they want but can't have. These dreams

often have something to do with sex and aggression (侵犯行为). Swiss psychiatrist Carl Jung worked

closely with Freud for several years, but he believed dreams could help people grow and understand

themselves. He believed dreams provide solutions (解决办法) to problems we face when we are awake.

He didn't believe dreams hide our feelings about sex or aggression. Today we know more about the science

of dreaming because researchers can take pictures of people's brains while they are sleeping.

     Other researchers are studying how dreaming helps our bodies work with problems and very sad emotions. Robert Stick gold is a professor of psychiatry at Harvard University in Massachusetts. Doctor Stick gold says

that when we dream, the brain is trying to make sense of the world. He does not agree with Sigmund Freud

that dreaming is the way we express our hidden feelings and desires.

      Scientists believe it is important to keep researching dreams. Doctor Stick gold says it has been more than

one hundred years since Sigmund Freud published his important book about dreaming. Yet there is still no agreement on exactly how the brain works when we are dreaming or why we dream.
