Situation: I am facing a chair by the bed and there is a door on my left.
Alternative situations: I am standing in front of a chair with a nightstand also in front of me to my right at 1 o'clock. I am picking up the chair in front of the radiator in front of me to place in front of the door to prevent people from entering on my left side.
Question: Which way is the light coming from that is not natural?
