* insufficient blood in the body, low hemoglobin and red blood cells.
* Blood vessel blockage, or fever and cold will affect the central nervous system of the brain.
* Sympathetic nerve function is out of order.
These may be premonitory symptoms of your dreams. Please adjust your living habits and adjust in time.
Dreams are individuals' subjective experience of random neural activities in the brain. Usually, a certain amount of stimulation is necessary to maintain the normal function of the brain and nervous system. In the sleep state, the stimulation is reduced and the nervous system produces some random activities. Dreams are a process in which the cognitive system interprets these random activities and gives them some meaning.
You may be stimulated by various contradictions in your life. I suggest you exercise more, relax physically and mentally, and let go of everything.
I have a way to regulate sleep here.
I wonder if you can practice?
It is the monk meditation method. First, roll up your legs according to meditation, straighten your waist and close your eyes slowly. The thumb of the right hand presses the groove between the thumb and forefinger of the left hand, and the other four fingers of the right hand hold the back of the left hand. The fingertips of the thumb and forefinger of the left hand hold each other. Put your palm between your legs. The tip of the tongue touches the palate and the secreted body fluids are swallowed. These actions must be prepared before closing your eyes. Meditation usually takes half an hour. Do not move. The first ten minutes are ok, but the effect is not obvious. When you meditate, you will feel your blood vessels beating and sweating all over. When you meditate, your mind must imagine that you are in a landscape you like ... don't move when you meditate, remember! ! !
If you don't feel sick, you just don't want to sit. It is impossible to practice. For example, sometimes I can sit all night. The next day is more energetic than sleeping. Of course, I fell asleep as soon as I sat down and woke up the same way.
I used this method to relieve physical fatigue and mental relaxation when I was in military training at the police academy.
