Don't close the door when you sleep.
From a psychological point of view, you should also close the door when sleeping, so as to give people a sense of security, ensure that your sleep quality is good enough, and be more conducive to falling asleep.
Shaqi is also a kind of breath that enters the house from the outside. People will encounter all kinds of suffocation when they go out every day, especially the road. This kind of suffocation will be more common. If you don't close the door when you sleep at night, these suffocation will probably enter your room, which will naturally further damage your physical condition and even make you suffer from serious diseases unconsciously.
Even if you don't talk about feng shui and psychological problems, it is difficult for a person to feel safe when sleeping without closing the door.
People have little consciousness when they sleep, so they can't sleep well if they are not in a safe environment. Leaving the door open at night is creating an insecure environment for yourself, which is naturally very bad.
