blissful sleep

Bliss without awareness, the unaware bliss is same as good sleep. Bad sleep is no sleep at all as your mind is disturbed and there is very little settling down. Good sleep is what you get naturally after the days work, your mind being undisturbed through out the day. Though unaware you get a glimpse of bliss during good sound sleep, and so deep sleep is always so good and refreshing. If unaware bliss is equal to such good sleep then, how will the bliss with full awareness be?
