First, the placement of the bed should pay attention to the problem of wall hangings around. For example, you can't hang a picture of a beast on the bedside. Imagine, when you are ready to sleep, suddenly seeing the beast at the head of the bed will make people too scared to sleep. I still have insomnia and many dreams at night, which affects my rest the next day. Many people have encountered similar situations.
Secondly, pay attention to the placement of the bedside. Generally speaking, it can't be placed under the main beam of the bedroom, which will make everyone feel depressed. From the perspective of Feng Shui, it is also bad, which will make the owner useless in his work and bound in his study. If the bed must be placed under the beam, you can put a ceiling on it, so that the beam can be covered, which will make everyone sleep well and boost their career.
Third, you can't hang a mirror on the right side of the bed, because the mirror is used to stop suffocation. It will bring bad luck if a mirror is set in the corresponding place of the bed. And when everyone wakes up in the middle of the night, the mirror will reflect light, which will stimulate the eyes and make everyone unable to sleep normally. More importantly, from the perspective of feng shui, this is also a taboo.
I hope I can help you!
