As for waking up and not dreaming, it's because I forgot. Usually two hours' sleep alone is enough. Why do some people sleep for seven or eight hours? That's your habit of lying in bed with a pillow to rest. We don't need that long sleep time, especially those who meditate and do kung fu know that as long as you close your eyes and really fall asleep for three minutes at noon, it is equivalent to sleeping for two hours, but you should make good use of the noon time. I will fall asleep at noon (at night 1 1 till the next morning 1), and five minutes is equal to six hours.
At this time, knowledge has greatly increased, with the laws of the universe, the laws of the earth, and the principles of the Book of Changes, Yin and Yang. Moreover, you will feel a force coming down from under the heart and merging with the strength of the abdomen (kidney). The so-called "fire and water ji ji", all of a sudden, you get enough sleep and are full of energy.
Therefore, people who have insomnia or really want to stay up late at night must sleep even for 20 minutes at noon. If they can't sleep, they should train themselves to sleep. You don't want to sleep after about 12: 30, which is bad.
What's more, at dawn, at four or five o'clock, at five or six o'clock, you are sleepy and want to sleep. If you sleep at this time, you will be sleepy all day.
Therefore, people who want to stay up late, even if there is a big thing, should put it down, sleep for half an hour, and don't sleep at 7: 00 (7: 00). The spirit of that day is enough.
However, people who suffer from insomnia can't sleep after 12 o'clock and toss and turn in bed. As a result, they fall asleep at dawn and get dizzy at noon the next day, so you will suffer from insomnia and lack of sleep. Actually, you have no experience.
I don't think it's very scientific
