Problem of pondering:
He was sitting in chair with eyes closed. No sound of snoring or palpable nostrils. I looked closely but no rapid eye moment was visible. He was not dreaming. Television was blaring news. It continued for about ten minutes, when I made a noise. ‘When you came? Was I asleep?’ was the response. He was not asleep. Just in deep thought. So when are we actually asleep or awake?
