4. MISCONCEPTION: REMEMBERING YOUR DREAMS IS AN INDICATOR OF GOOD SLEEP.
误解四：记得梦说明你睡了个好觉
Some people say that remembering your dreams in the morning is an indication of a good night"s sleep, but that"s not true. In fact, people with poor sleep are more likely to remember their dreams. According to a 2014 report in Cerebral Cortex, study participants who remembered their dreams had twice as much "wakefulness," which could be taken to mean they woke up more often. People who remember their dreams also have higher activity in the temporoparietal junction, a part of the brain that processes information and emotions. They also reacted more strongly to sounds, which could help explain their interrupted sleep patterns. Basically, people who are sleep-deprived tend to have greater sleep intensity during the precious few hours they manage to sleep, which leads to more vivid dreams.
