Usually, people work during the day and sleep at night. When working and studying, the human brain is in an excited state; When sleeping, the brain is in a state of inhibition, and it is generally unable to perceive strong external stimuli such as slight sounds or weak skin contact. However, the degree of inhibition on the brain is different. If sleep is immature or just falling asleep, external stimuli will affect the brain, and a part of the cerebral cortex will get excited, so people will dream. If he is cold, he will dream of walking barefoot in the ice and snow; If his gums are swollen, he will dream that all his teeth have fallen out; If he has the feeling of urinating, then he will dream of looking for the toilet everywhere, and he will be anxious as hell. As long as dreams are related to thoughts, wishes, imagination and memory.
Dreams are illusory, not real. Generally speaking, if there is a bad omen in your dream, it means that you are under great pressure and think too much. You should be careful in reality. If the dream is auspicious, it means that the dream is smooth and relaxed. Don't be too proud in reality, just relax. In a word, you can't trust all your dreams, and you can't trust them. Grasp yourself, and it is most important to live a wonderful and happy life.
