A thought that's been zigzagging its way through my synapses for awhile now.
It's kind of like this -- there's stuff that has positive ontological "content". It "takes up room" in "being". Whatever that means. But this stuff is constantly passing into non-being, constantly ceasing to exist. I don't know where the stuff originally comes from -- the big bang? -- but it doesn't matter, it could never be comprehended anyway. The point is that subjective experience is the means by which this constant ceasing-to-exist happens.
So I'm looking at a computer screen right now, as I type, and this computer screen (whatever it ultimately is) has positive ontological content that is, right now, passing into nothingness. And that "passing into nothingness" = my perception(s) of the computer screen.
To put it another way, where does what we perceive "go" when we perceive it? Sure it "goes" into our memories to some degree, but that's just the trace of it. Where does the thing itself go? Nowhere -- it dissolves. Our perception of it is precisely that dissolution.
Water going over the edge of the cliff -- consciousness as that edge.
This is way too metaphysical for even my taste, but it's a thought that keeps bubbling up to the surface of my attention, so I'm starting to think there's *something* to it, even if the thought itself is functioning as a kind of metaphor for something I'm not fully aware of (like the metaphorical aspect of dreams).
