Dreams are expressions of thoughts, 求翻译
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 nightmares -- bad dreams that frighten us.
Artists, writers and scientists sometimes say they get ideas from dreams. For example, the singer Paul McCartney of the Beatles said he awakened 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.
In China,people believed that dreams were a way to visit with fanily members who had died.Some native American tribes and Mexican civilizations believe dreams are a different world we visit when we sleep.
