Why can't the mirror be put on the bed?

Religion: It is said that some gods can reach the underworld through mirrors. If the mirror is facing the bed, the bed will become the channel for souls to enter the underworld, while people will sleep in the bed. The soul will shuttle back and forth in bed, which will have a negative impact on the human body over time. There is also a saying that mirrors are one of the things that tend to get cloudy. People belong to yang and yin belongs to yin. As long as the above statement is made, it will have a negative impact on the human body. Scientific statement: The mirror placed on the opposite side of the bed will make people feel oppressive and affect their sleep, which will be harmful to the human body after a long time. There is also a geomantic saying that the mirror will interfere with the surrounding gas field, thus disrupting the gas field order in a pattern. The mirror is in front of the bed. If nothing happens, it means that the place where the mirror is placed has no effect on the gas field. If it is not properly placed, it will interfere with the gas field in the pattern and bring negative effects to people.
