Lucid dream,Professor LaBerge, a physiological at Stanford University in the United States, defines lucid dream as knowing what to do when dreaming,1,Lucid-Dream-清醒梦-心理学,Lucid dream is different from the normal dream,Normal Dream In the normal dream, we often wake up only to find that had just done a dream, but it is difficult to remember what happened in the dream, even do not remember the dreams, not to talk about of control dream. Lucid Dream The biggest difference, people can consciously dominate their own behavior, control the development of the story. Second, people have almost the same logical thinking and memory on awake. And most of the time. Lucid dreamers wake up after, the mood will be very pleasant,1,2,3,2,Lucid-Dream-清醒梦-心理学,The occurrence of lucid dream,There are five stages of human sleep, on rapid eye movement (REM) stage that the peoples consciousness is most active. At this stage people enter deep sleep, the eye will quickly turn. Numerous studies have shown. Lucid dreams generally occur during rapid eye movement (REM) stage on sleep,4,3,Lucid-Dream-清醒梦-心理学,During the first sleep cycle, these five sleep stages are not performed in a order line From stage 1 to stage 4, then directly into the REM stage, Or stage 1 to stage 4, then returns to stages 3 and 2, and then directly into the REM stage, Or other form, followed by five stages Recurring. Every 60 to 90 minutes, these five sleep stages will be repeated once, the general REM stage will continue for 10 to 30 minutes each time. Every night, we basically go through 4 to 5 REM stages,4,Lucid-Dream-清醒梦-心理学,And most of our dreams, whether remembered or forgotten occur at this stage, and lucid dreams also occur during the unusually active sleep stage (REM Stage)of the brain. In general, we do not make dream within a sleep beginning few hours, because our sleep has not gone through the first four stages to REM sleep stage. Therefore, in a sense, the longer we sleep, the more chance to do lucid dream. This also explains why peoples dreams, especially the lucid dream, mostly occurred in the morning before going to get up that period, and the content of the dream is very rich,5,5,Lucid-Dream-清醒梦-心理学,Most people have such a feeling, in fact, not a long period of time we have done a lot of very long time dream. I feel like I have been sleeping for a few hours. This is because the brain is in a very active REM sleep stage and the active brain to process information more quickly, which makes our dreams look very real and lasting,6,6,Lucid-Dream-清醒梦-心理学,Classification of lucid dreams,Usually lucid dream that of the way people dream of different so divided into two kinds: One is the transition from the normal dream into a lucid dream In general, we usually do most of the lucid dream belongs to the former, We are often in a dream when we suddenly realize that we are dreaming. Before to this, we have been in a state of unconscious dream,7,7,Lucid-Dream-清醒梦-心理学,The other is directly from the awake state into a lucid dream. This direct access to a lucid dream from a state of awakening means that when you start dreaming you realize that you are dreaming, a lucid dream in this way usually requires the help of an external force,8,8,Lucid-Dream-清醒梦-心理学,Lucid dream of training,Specifically divided into the following three steps: Step 1: Remember your dream. In this step, dreamers are required to remember their dreams every day. And recorded as a diary. As much as possible to deepen their understanding of the dream and memory. Step 2: Reality test. Reality testing is a common way of telling people whether they are in a dream. Its principle is through the dream that some of the opposite phenomenon with the real world to find out whether they are in a dream. Step 3: meditation. The study found that there is a delicate link between meditation and a lucid dream. The longer the time of meditation during the day, the easier it is to make a clear dream at night,9,Lucid-Dream-清醒梦-心理学,Distinguish:Reality test,The deeper degree of sleep, our unconscious will be more active, our dreams will become more vivid. Sometimes, our dreams seem too real, so that even our self can not know whether it is a reality or a dream, at this time, people need to conduct a Reality test to distinguish. Reality test refers to finding or discovering a phenomenon or behavior different from reality in a dream, and then distinguish whether we are in a dream,10,Lucid-Dream-清醒梦-心理学,LaBerge pointed out in his book that it is difficult to perform two actions in a dream: one is reading He believes that people can not complete the reading work in a dream, whether it is reading the text or time, when people look elsewhere after reading back to the same place, the text and time will be an abnormal change. The other one is turning the light on or off After observation that the lamp can not work in a dream,9,10,11,Lucid-Dream-清醒梦-心理学,Thus, we can conduct a reverse thinking, the use of these two actions to tes
