I have backed away from this discussion as it became too esoteric and I started losing track but... is that not what the entire discussion is all about? Whether there even is such a thing as "real" reality, independent of the observer. Our everyday intuition seems to confirm its existence but is it really objective or just a construct of our limited senses, processing power and perhaps frame of reference? After all, there are domains (quantum effects, more-that-four dimensional spaces, even plain old four-dimensional spaces but with a different configuration of time and space dimensions, such as inside black holes) where our everyday intuition fails spectacularly.
