VOICE TWO:

And I'm Barbara Klein with EXPLORATIONS in VOA Special English. Do you dream? Do you create pictures and stories in your mind as you sleep? Today, we are going to explore dreaming. People have had ideas about the meaning and importance of dreams throughout history. Today brain researchers are learning¹ even more about dreams.

VOICE ONE:

Dreams are expressions of thoughts, feelings and events that pass through our mind while we are sleeping. People dream about one to two hours each night. We may have four to seven dreams in one night. Everybody dreams. But only some people remember their dreams.

The word "dream" comes from an old word in English that means "joy" and "music." Our dreams often include all the senses – smells, sounds, sights, tastes and things we touch. We dream in color. Sometimes we dream the same dream over and over again. These repeated dreams are often unpleasant. They may even be nightmares² -- bad dreams that frighten us.

VOICE TWO:

Artists, writers and scientists sometimes say they get ideas from dreams. For example, the singer Paul McCartney of the Beatles said he awakened³ one day with the music for the song "Yesterday" in his head. The writer Mary Shelley said she had a very strong dream about a scientist using a machine to make a creature come alive. When she awakened, she began to write her book about a scientist named Frankenstein who creates a frightening monster.

VOICE ONE:

People have been trying to decide what dreams mean for thousands of years. Ancient Greeks and Romans believed dreams provided⁴ messages from the gods. Sometimes people who could understand dreams would help military leaders in battle.

In ancient Egypt, people who could explain dreams were believed to be special. In the Christian⁵ Bible⁶, there are more than seven hundred comments or stories about dreams. In China, people believed that dreams were a way to visit with family members who had died. Some Native American tribes⁷ and Mexican civilizations believed dreams were a different world we visit when we sleep.

In Europe, people believed that dreams were evil⁸ and could lead people to do bad things. Two hundred years ago, people awakened after four or five hours of sleep to think about their dreams or talk about them with other people. Then they returned to sleep for another four to five hours.

VOICE TWO:
　
Sigmund Freud

Early in the twentieth century, two famous scientists developed different ideas about dreams. Austrian psychiatrist⁹ Sigmund Freud published a book called "The Interpretation¹⁰ of Dreams" in nineteen hundred. Freud believed people often dream about things they want but cannot have. These dreams are often linked to sex and aggression¹¹.

For Freud, dreams were full of hidden meaning. He tried to understand dreams as a way to understand people and why they acted or thought in certain ways. Freud believed that every thought and every action started deep in our brains. He thought dreams could be an important way to understand what is happening in our brains.

Freud told people what their dreams meant as a way of helping¹² them solve problems or understand their worries. For example, Freud said when people dream of flying or swinging, they want to be free of their childhood. When a person dreams that a brother or sister or parent has died, the dreamer is really hiding feelings of hatred¹³ for that person. Or a desire to have what the other person has.

Swiss psychiatrist Carl Jung worked closely¹⁴ with Freud for several years. But he developed very different ideas about dreams. Jung believed dreams could help people grow and understand themselves. He believed dreams provide solutions to problems we face when we are awake.

He also believed dreams tell us something about ourselves and our relations with other people. He did not believe dreams hide our feelings about sex or aggression.

VOICE ONE:

Today we know more about the science of dreaming because researchers can take pictures of people's brains while they are sleeping.

In nineteen fifty-three, scientists discovered a special kind of sleep called REM or rapid eye movement. Our eyes move back and forth¹⁵ very quickly while they are closed. Our bodies go through several periods of sleep each night. REM sleep is the fourth period. We enter REM sleep four to seven times each night. During REM sleep, our bodies do not move at all. This is the time when we dream. If people are awakened during their REM sleep, they will remember their dreams almost ninety percent of the time. This is true even for people who say they do not dream.

VOICE TWO:
　
Salvador Dali's 1931 painting "The Dream." His paintings were often influenced by unusual dream-like images.

One kind of dreaming is called lucid¹⁶ dreaming. People know during a dream that they are dreaming.

An organization in Canada called the Dreams Foundation¹⁷ believes you can train yourself to have lucid dreams by paying very close attention to your dreams and writing them down. The Dreams Foundation believes this is one way to become more imaginative¹⁸ and creative. It is possible to take classes on the Internet to learn how to remember dreams and use what you learn in your daily life.

There is a great deal of other information about dreams and dreaming on the Internet. There is even a collection of more than twenty thousand descriptions of dreams called the DreamBank. People between the ages of seven and seventy-four made these dream reports. People can search this collection to help understand dreams or they can add reports about their own dreams.

VOICE ONE:

Scientists have done serious research about dreams. The International Association¹⁹ for the Study of Dreams holds a meeting every year. At one meeting scientists talked about ways to help victims of crime who have nightmares. Scientists have also studied dreams and creativity, dreams of sick people and dreams of children. The group will be meeting next month in Chicago, Illinois. An Australian professor named Robert Moss²⁰ will talk about how dreams have influenced history.

For example, he says Harriet Tubman was able to help American slaves escape to freedom because she saw herself flying like a bird in her dreams. Mister²¹ Moss also teaches an Internet course to help people explore and understand their dreams.

(MUSIC)

VOICE TWO:

Scientists who study dreaming often attach wires to the head of a person who is sleeping. The wires record electrical activity in the brain. These studies show that the part of the brain in which we feel emotion is very active when we dream.

The front part of the brain is much less active; this is the center of our higher level thinking processes like organization and memory. Some scientists believe this is why our dreams often seem strange and out of order.

Researcher Rosalind Cartwright says the study of dreams is changing because scientists are now spending more time trying to understand why some people have problems sleeping. Miz Cartwright says for people who sleep well, dreaming can help them control their emotions during the day. Researchers are still trying to understand the importanceof dreams for people who do not sleep well and often wake during the night.

VOICE ONE:

Other researchers are studying how dreaming helps our bodies work with problems and very sad emotions. Robert Stickgold is a professor of psychiatry²² at Harvard University in Massachusetts. Doctor Stickgold says that when we dream, the brain is trying to make sense of the world. It does so by putting our memories together in different ways to make new connections and relationships. Doctor Stickgold believes that dreaming is a biological process. 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 Stickgold 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 works²³ when we are dreaming or why we dream.
