Fear of insomnia: Many insomniacs worry about not being able to sleep once they go to bed at night, or try to get themselves to sleep quickly, which is counterproductive. The higher neural activity of the human cerebral cortex has two processes: excitation and inhibition. During the day, brain cells are in a state of excitement, and after working all day, they need to rest and enter a state of inhibition and sleep. After a night of rest, they naturally turn awake again. The excitation and inhibition of the cerebral cortex are coordinated with each other, alternating to form the rhythm of sleep from week to week. “Fear of insomnia and wanting to sleep” is meant to be sleep, but “fear of insomnia and wanting to sleep” is itself an excitement process of brain cells, so the more fear of insomnia and the more you want to sleep, the more excited your brain cells are, so you are more likely to lose sleep. Dreams harmful psychology: can not correctly look at dreams, that dreams are poor sleep performance, harmful to the human body, and even mistakenly think that more dreams is insomnia. These misconceptions often make people anxious and worried about dreaming after going to sleep. This “vigilance” psychology, often affect the quality of sleep. In fact, science has proved that everyone dreams, and dreaming is not only a normal psychological phenomenon, but also a way of working of the brain. Reenacting daytime experiences in dreams helps memory and cleans up useless information. Dreams themselves are not harmful to the human body, what is harmful is the idea that “dreaming is harmful”, so that they have a psychological burden. Self-blame: Some people feel guilty and blame themselves after a mistake, replaying the mistake in their minds and regretting that they did not handle it properly. During the day, due to more things, self-blame and remorse is a little lighter, to the night is “wandering” in the self-blame, remorse fantasy and excitement, long sleep. Expectation psychology: worry about oversleeping and miss work, so there are often early awakening. For example, a “three-shift” webmaster, due to the night shift (12:00 at night to work), often at 7:00 pm to sleep. He was afraid of being late to sleep, and often woke up after 1 to 2 hours of sleep, and over time became a patient of early awakening. Some people are also in a state of anticipatory excitement and have difficulty sleeping before the results of promotions, title evaluations, and room assignments are about to be announced. Reproduction of childhood trauma psychology: Some people are afraid due to childhood trauma such as loss of parents, intimidation and heavy punishment, and the phenomenon of not being able to sleep for fear of darkness appears. However, in adulthood, due to some traumatic stimuli similar to those in childhood, the traumatic psychological reactions of childhood that were suppressed in the subconscious will be reproduced and the insomnia in childhood will be repeated. The psychology of being at a loss for words: Some people cannot make the right reaction after being stimulated by unexpected events, and they are at a loss for words, so that when they sleep at night, they also look forward and backward, think left and right, and are always in a state of anxiety and excitement of being in and out and uncertain.
