1 When sleeping at home, I sometimes hear the sound of the head of the bed being beaten. It is now k

This sensation is a cranial nerve inhibition.

After the Shenyuan Sutra reaction, because after a person enters deep sleep, the capillaries of the brain will constrict and enter an inhibited state, the blood flow is slow, and some normally active nerves enter a resting state, while the autonomic nerves that are usually awake in an inhibited state, such as part of the spinal cord, brainstem, etc., will become active and more sensitive to external stimuli, and at the same time, the brain is also easy to recover the memory of previous experiences, which is unconscious, you can feel it, but you can't control it. So you can feel the knee being beaten.

The inhibition of blood vessels in sleep is the cause of cerebral hemorrhage in many elderly people, of course, you are still young, don't worry about this, if you feel that your legs are knocked very annoying, you can remember to massage your legs before going to bed, and clearly hint to yourself, if someone hits you, kick him, so that you can get rid of this unconscious memory by insisting on it a few times.

It is recommended to take a small dose of sedatives or drugs to promote blood circulation before bedtime, and consult a doctor according to your physical health.

The above is a more scientific explanation, if from the perspective of superstition, please put some sharp weapons, such as kitchen knives, axes, etc., under the bed, can play a role in suppressing evil spirits and suppressing shock. Water is isolated in feng shui, and you can put a basin of water near the head of the bed. At the same time, the bedroom layout should not have light or air leakage.

Believe it or not, there are many things that science can't explain, so let it be.

I feel that psychology is big and medicine is small.
