Many people in foreign countries have mirrors facing the bed in their bedrooms. I remember there was another kind of bed in the past, that is, a bed surrounded by three sides, with mirrors on three sides of the bed.
But from the perspective of modern geomantic omen, mirrors are really bad for beds. If you face the bed, you can see yourself lying there. Psychologically, turning off the lights will really bring you some fear and affect the quality of sleep.
In fact, the most important thing is to see if you feel mental stress. If not, there is no harm. Feng Shui, which has certain scientific basis, is purely an environmental psychological and physiological problem. Because many foreign families are taboo about Feng Shui from any angle, they are not affected at all, just because they don't have this folk culture and lack this psychological hint.
Therefore, modern Feng Shui is actually "environmental psychology", beyond which you can basically laugh it off, so there is no harm if you don't have any psychological pressure, and it can't be changed now. If you feel psychological pressure, then see if you can change the cupboard door.
