Awakening, Dreaming and Deep Sleep

In a few short hours, when i fall asleep, the whole universe will disappear from my awareness. My identity as this person will disappear to be replaced by a dream universe. And again, the waking world will appear. In this way, waking, dreaming and deep sleep come and go. They rotate endlessly in me, the awareness. I'll wake up and sit up in my bed,. Here is the same world. Here is the body.
