Situation: I am napping on a couch that is perpendicular to a wall, my head is resting on a pillow and there is a door just in front of me.
Alternative situations: I got up from the couch and a table is to my right. I''m sitting on couch with my legs over the arm rest of couch facing towards the door with panic hardware across from me.
Question: Which object in front of me could wake me up with a loud sound?
