Finite body/mind thinking and feelings called ‘experience’ in time/space are totally affected by content – by apparent ‘happenings’ that come and go in duality, and which we ‘think’ and believe is reality.
Non-dual awareness of that experience is not itself affected; it is objectless, choiceless, undisturbed, infinitely peaceful – as waves do not disturb the deep ocean, so to speak. At night, we mostly dream but also, variously – depending on ones’ inner state – enter into deep objectless sleep; one rests there, in timeless being, in real peace that has no objects, ie no conflicts, no dreams.
In fine, deep sleep is a non-experience, but there is this subtle awareness of it too; we feel deeply rested and restored in the morning, but most of us don’t ‘know’ it experientially, and don’t realize this aware, timeless being. With grace, awareness-of-that-awareness, happens, and that’s apparently happening more these days, yes, as one rests in quietly listening, learning and loving it all. 🙂
