　　Common Questions about Dreams

　　Does everyone dream?

　　Yes. Research shows that we all dream. We have our most vivid dreams during a type of sleep called Rapid Eye Movement (REM) sleep. During REM sleep, the brain is very active. The eyes move quickly back and forth1 under the lids, and the large muscles of the body are relaxed. REM sleep occurs every 90-100 minutes, three to four times a night, and it lasts longer as the night goes on. 1 We dream at other times during the night, too, but those dreams are less vivid.

　　Do people remember their dreams?

　　A few people remember their dreams. However, most people forget nearly everything that happened during the night 一 dreams, thoughts, and the short periods of time when they were awake.

　　2 It seems that the memory of the dream is not totally lost，but for some reason it is very hard to bring it back2. If you want to remember your dream, the best thing to do is to write it down as soon as you wake up.

　　Are dreams in color?

　　Most dreams are in color. However, people may not be aware of it for two reasons ： They don，t usually remember the details of their dreams, or they don，t notice the color because it is such a natural part of our lives. 3 Do dreams have meaning?

　　Scientists continue to debate this issue.3 4 Some people use dreams to help them learn more about their feelings, thoughts, behavior, motives, and values. Others find that dreams can help them solve problems. It’s also true that artists, writers, and scientists often get creative ideas from dreams.

　　How can I learn to understand my dreams?

　　The most important thing to remember is that your dreams are personal. The people, actions, and situations in your dreams reflect your experience, your thoughts, and your feelings. Some dream experts believe that there are certain types of dreams that many people have, even if they come from different cultures or time periods. Usually, however, the same dream will have different meanings for different people. For example, an elephant in a dream may mean one thing to a zookeeper and something very different to a child whose favorite toy is a stuffed elephant. 5 Then look for links between your dreams and what is happening in your daily life. If you think hard and you are patient, perhaps the meaning of your dreams will become clearer to you.
