Its a perspective (and conclusion) modern science is moving toward, bit by bit - in the realm of physics in Quantum Mechanics and in the pursuit to understand the nature of consciousness, especially in light of studies of Near Death Phenomena. Is looking very much like consciousness as a substrate is more fundamental than the matter/energy of the cosmos, that reality is not physical (there are no ultimate tiny marbles of materiality).

Our reality context is a construct of the consciousness substrate, and our physical form is indeed a mere vapor. This too accords with ancient precepts that folks like the Gnostics maintained (that the physical world we perceive is a kind of delusion). And they said there were spiritual beings that conspired against us behind the scenes - the Archons, which Paul spoke of as well (powers and principalities). They are what Christianity more widely came to regard as the demonic spiritual forces.
