Hi Eckard,
Yes, I believe that physical reality does not depend upon the perspective of an observer, but 'physics', the map of reality, generally does to a large extent.
And in quantum theory this includes "counterfactuals" and perhaps other concepts that may affect theory.
Although logical structures in the brain are quite flexible, I do not believe that the structures that we use to map the world are 100 percent integrated or otherwise seamlessly overlapping. Certainly these maps differ from brain to brain, and I believe they are similarly dis-integrated in one brain. And I am not sure whether or not there are logical issues having to do with the way our brains process self-referential logic.
The point is that physics (per d'Espagnat) is based on realism, logic, and locality, and most Bell theorists have decided to forego realism and locality in favor of retaining logic. But to me, logic is the most mysterious and least understood aspect of the three, while both my theoretical model and my mind tell me that local realism is valid. I cannot prove that the problem lies with logic, but I do not consider that anyone has proved that local realism is false. If I'm forced to choose, based on incomplete knowledge, I choose local realism and fuzzy logic (not "the" fuzzy logic).
As for Kyle's topic, I had missed it until I saw Georgina's comments. The topic is not an easy one to discuss. I have written in past contests about the effects on perception which I interpret as 'suppressing' metric awareness of distance and difference in favor of topological awareness of connectedness and unity. It is, in general, not a topic that goes anywhere as most who have not experienced it have no idea what is being discussed, while most who have experience of it have not the physical or metaphysical concepts to make sense of the experience.
I hope this response addresses your comment.
Best,
