Damn it. How long has it been? One night, I woke up from my sleep and couldn't move my hands and feet. I saw a mass of black fog in the room, which dissipated after a while. Then people can move.

This should be a stiff neck. Sometimes I am too tired or in a bad mood during the day. In the evening, when MUBI saw the fantasy, he paid more attention to rest. Go to bed early, get up early and do more exercise, so you won't see this phenomenon again. In other words, from an idealistic point of view, this is a lack of yang, and yin will only be seen when it is heavy. Therefore, strengthen exercise, improve physical fitness, and have sufficient yang, and these things you said will naturally disappear. .
