I took a look at another view of Consciousness and Awareness. One website said, which I am starting to agree with because of personal experiance, that Awareness is the perceptive ability of the Self. Which the Self is Being-Consciousness-Bliss .
Also, the reason why we are not conscious when we are sleeping is because we are externalized, meaning we are identifying with the external world. When we go to sleep in that state we become "unconscious" because we are externalized and the external world has dissapeared. Unconsciousness, as I see it, is an illusion created by the contaminated mind.
