Seriously, sleep is about inner peace, not environmental peace. It can be said that some people fall asleep immediately when lying on the grass, some people can fall asleep on noisy square stools, and some people can't sleep even if they close the door in the villa. The fundamental reason is that their hearts are not clean enough, and a little interference from the outside will lead to great fluctuations in their hearts, leading to rising anger at all times and disturbing their minds. However, people can control everything, for example, you can blink if you want, and you can leave if you want. Run if you want, it doesn't matter what others think. As long as you always control your inner thoughts and emotions, you can control yourself immediately when you are upset and you can control yourself when you are crazy. You can sleep with your demons and it's none of others' business. The bad behavior of others only strengthens the power of the devil, and your own control ability is always the strongest. If you follow my control method above, it may not work well at first. Gradually, you will feel that others can't influence you. You can sleep soundly even if it thunders and cannons outside. There may even be people with extremely strong psychological quality. Even if the knife is on their necks, they will fall asleep immediately when they close their eyes. To achieve this state, it is not just sleeping. He must have very good values, which made him look down on life and death. So, it is not a problem at all. It's basically his own problem. He can't do it by himself.

Of course, there are shortcuts, that is, moving out to rent a house, or communicating with roommates, or even taking sleeping pills. These methods are all based on external things, which can be said to be only temporary.
