My point Frank is that even illusions, if real illusions indeed, are still objects of reality, if you experience them. Note that I am not attempting to validate or explain experiencing has a bed rock like Fresco does...just saying that whatever it is you experience, illusion or not, such experience is just as much a part of reality as anything else. If I were to be a radical philosopher, which I am not, I don't have the stomach or energy for it, I would say that all experience is valid. What we call "illusion" because not totally disconnected from the whole might just refer to a very narrow connective point for pov, that transforms perspective to a very particular almost not shareable form of knowledge.
Say you and only you in the world have a blue pair of glasses while everyone else has an orange one...well guess what, both your and their experiences of the world are valid experiences, after all, I am setting the rules for this world, both your glasses and everybody else's glasses exist and are part of the main world along with people... but guess who will be deemed eluded ? yep, you with your blue pair of glasses...
What I am attempting to speak about is that bottle necked pov entrances with very little connections dots twist povs so very much that they become socially not shareable... but given how data is processed through those bottle necked connectors, twisted data, still represents, is, valid data about everything else. It could even be reversed untwisted. Information there is not false no doubts.
This is very hard to explain I don't know if I was clear enough.
