For most individuals, a large part of their consciousness is unconsciousness where their limited awareness consists of repeating subroutines of the mind consisting of reactions and anxieties, social conditioning, daydreaming, and mental programming. For others consciousness is mental and they are capable of staying in the awareness of now longer rather than being lost in repeating mental loops. At a broader level of consciousness one begins to be aware of the field of consciousness of the heart and the rest of the body as well as the mind. Further on one becomes aware of and incorporates other expressions of awareness of their self that could be called their higher self and their “past lives”. Finally the broadest consciousness I am know of comes with the awareness of self as a quantum self; permeating all life and permeating the universe.
In all consciousness is experiential. Just being aware of these differences of consciousness does not mean that one has attained or can sustain them.
