Situation: I am standing by the bed and leaning on the wall. I am facing the desk.
Alternative situations: I slept on the opposite side of the window. Now I am getting out of bed and walking away from the bed. I am walking from the head of the bed and the wall is on my right side. I walk up out of bed and go over to my desk that is in front of me.
Question: How many lamps can I see?
