Bed, it is absolutely impossible to sleep in someone else's old bed. First of all, because the old bed will leave a bed owner's aura, if we sleep in this bed, it will be easily affected. If the owner of the last bed died of illness, then when you sleep in this bed.
Because the unlucky magnetic field still exists, it will transfer the bad luck of the former bed owner to you and cause harm to your health.
Secondly, even if the previous owner of this bed was healthy, it must have been replaced for some reason. The Feng Shui effect it left still exists on this bed, which will have a certain impact on you to some extent, so it is best not to sleep in the old bed. When choosing a bed, you should choose a bed that suits you according to your five elements, which is beneficial to you.
