Writing about those atypical experiences is quite difficult. It seems our language heavily assumes the default unmindful experience so doesn’t have precise ways to express the opposite.
According to Advaita, there is no separate self/person, except as an abstraction made out of identification with various phenomena that arise in the field of consciousness. Once you see this (LSD helps), it is immediately self-evident that this has always been the case. Think Decker at the end of Blade Runner realizing he's a replicant. The person ("you") realizes they have never been anything more than a collection of phenomena.
Accepting this enables one to sit back and rest as consciousness, observing without involvement as the person's life lives itself in a perpetual flow state.
Obviously an illusion, since your brain is doing the task. The "conscious" part of the brain is apparently unaware of most of what the brain is doing. I feel that way most of the time, actually, that I don't need to consciously micromanage everything that I'm doing, since the brain still gets it done in any case. I feel that way now while writing this sentence, I'm consciously just watching the words as they appear.
