My point, here, is that what we call "reality" (and the 'truth of reality') is a conceptual abstraction generated in our minds; derived from our very limited experiential perception and understanding of the phenomena of existence. What I think you are trying to point to as your 'reality degree meter' is the level of complexity involved in that conceptual abstraction. If I write a story about my neighbor, and you read the story, to you, my neighbor becomes "just a character in a book" - not a 'real' person. The level of abstraction has increased, for you, because you did not experience the man directly, you experience him through my writing of him. But I would submit that the level of abstraction that stands between any one of us and any aspect of existence varies wildly, relative to each of our individual circumstances and experiences. And so the "reality" that we conceptualize from our experiences are likewise highly relative and very subjective. Science may create the illusion of providing us with a way around all this relative and subjective conceptualizing of the 'truth of reality', but it doesn't provide us any way of escaping or transcending the limitations of who and what we are, and so the illusion remains just that, an illusion.
