In this kind of psychological activity, the whole process of individual physical and mental changes is called dreaming. In a typical night sleep, the average person's first dream appears about 90 minutes after falling asleep. The duration of the dream is about 5- 15 minutes (average 10 minutes). During the whole night's sleep time, dreams appear in cycles at all stages of sleep, with about 4-6 dreams a night. Total * * * about 1-2 hours of sleep time, is in a dream. People dream when they sleep, and dreaming is a normal physiological phenomenon of the human body. Dreams are carried out in rem sleep and will be remembered; On the contrary, dreams in non-REM sleep will not be remembered, and we will not realize it. Everyone dreams every night, because people's brain cells are always moving, and the clarity of consciousness will be reduced during sleep. When thoughts, memories and imaginations in daily life stimulate some parts of human cerebral cortex and leave traces, when these parts of cerebral cortex are still excited during sleep, the traces left in daily life will become active and cause dreams, which is the existence of internal and external factors in human brain. As the saying goes, "Dreams don't come true", when you are desperate for something, you will dream at night. Once your dream really comes true, you will feel that your dream really comes true. Professor Zhang told reporters that this statement makes no sense. Interpretation of dreams is just a coincidence, and it is the result of connecting some irrelevant things by sensitive, suspicious and extreme people.

When the cerebral cortex is excited, people will not only talk nonsense, but also dance, gnash their teeth and even sleepwalk when they are asleep.
