There’s a difference between reality and the experience of reality. There’s objective reality and there’s subjective reality. However, objective reality isn’t merely that which can be quantified. Because that which can be quantified is actually part of a subjective experience.
There are certain “laws” that govern this realm we’re living in, but those laws are themselves part of a subjective experience. Not that they work differently for each person — they’re universal in the sense that they’re “constant,” regardless of our individual perceptions. They’re “objective” as far as this realm goes, but they aren’t necessarily the Ultimate Reality.
We’re experiencing a version of reality. Not objective reality itself. And we experience this version of reality through our natural senses, which are themselves governed by the laws of this version of reality.
