Situation: I am facing a bed, while there is a nightstand on my right and an armchair behind me.
Alternative situations: Feeling sleepy , I walk to bed and then the telephone on top of the nightstand at my right start ringing. I am standing and facing the bed from the side, nightstand to my right , trying to unroll my blanket so I can go under the blanket when I go to the bed in front of me.
Question: If I went to sleep what in the room could I use to wake me up?
