I'm not convinced we even need to have levels of awareness. Awareness is awareness, plain and simple, if you want to add in thought and emotion, then I suppose you could sense different levels of feeling, but awareness is like consciousness, you're either consciousness or you're not
Consciousness has no need for emotion or thought, hence the need to create physical reality to experience thought and emotion. Realise that consciousness is you, consciousness is perfect, you're just having an imperfect experience called physical reality.
No levels are required, they are just labels to make something very simple, overly complex.
