The door of my small bedroom faces north, and it is opposite to the entrance door. The window faces south, and the east-west direction is very narrow. Where should I put the bed?

generally speaking, according to the earth's magnetic field, the head south and the foot north are the most scientific and can improve the sleep quality. However, in some places, it is customary not to point the bedside directly at the door (this is like a funeral for the dead). So the most common direction of your bed in this room is the east-west direction. If it is too narrow, you can only leave a curtain on the bed by the window.
