The Meanings of Dreams
Sleep and dreams have interested people for centuries. Scientists are learning more about sleep, but they still know very little about why we dream.
小题1: 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. 小题2: While we are asleep, it works more slowly and sometimes puts our thoughts and memories together in strange ways.
小题3: Some believe that our dreams are associated with thoughts and feelings that we experience while we are awake. Many dream researchers think that a dream about death, for example, is really about an important life change. 小题4: Dreams about a car or travel often represent feelings about your own life. Dreams about teeth – especially broken or loose ones may indicate stress and fear. Dreams in which you are flying often represent freedom or escape.

can tell us something about ourselves. If the person in the dream was yelling (叫喊), for example, maybe you are angry. 小题5:
