Just Wondering

Can sentience be completely and utterly non-corporeal, without ties of any kind to matter or energy, normal or dark, positive, negative or anything in between?

If any such ties are essential, must they be continuing or merely historical, perhaps an evolutionary phase.

Would any such sentience have awareness of us, would it have to be unique, would it have to be singular or could it instead also be part of a greater whole? If so, would that greater whole involve parallel sentients or hierarchical.

If any of the foregoing are so, how might we perceive them? Have we perceived them, or it, or him or her?

Just wondering.
