Passage Four
Sleep and dreams have interested people for centuries.Scientists are learning more about sleep,but they still know very little about why we dream.
Modern research can tell us some important things about dreams.First,we have most of our dreams during REM (Rapid Eye Movement) sleep.At this time,the brain is very active.Second,everyone dreams – even if we cannot remember doing so when we awaken.Finally,a part of our brain helps us to understand daily experiences we have.While we are asleep,it works more slowly,and sometimes puts our thoughts and memories together in strange ways.
Although scientists do not know for certain why we dream,some believe that our dreams are associated with thoughts and feelings that we experience（经历）while we are awake.Many dream researchers think that a dream about death,for example,is really about an important life change.Dreams about telephones are thought to be about giving or receiving an important message.Dreams about a car or travel often represent（表示）feelings about your own life.Dreams about teeth –especially broken or loose ones may indicate（表明）stress（紧张）and fear.Dreams in which you are flying often represent freedom（自由）or escape（逃跑）.
Dream researchers think that people in our dreams can tell us something about ourselves.If the person in the dream was yelling,for example,maybe you are angry.If he or she was scared （恐惧）then maybe you are afraid of something.
There is still a lot about dreaming that we do not understand.By learning more about our dreams,we may learn more about ourselves.
