From higher levels of consciousness, our current waking-state is just as obviously impossible. What we experience in these states begins to look more and more like a quantum reality.
So, we have multiple, illusory, subjective realities -- each appearing real from within -- but different worlds, with different rules. And one Objective Reality, beyond time, change, matter, energy, or diversity; a steady state of quantum potentiality.
Reaching such a unified state is the goal of Hinduism.
You clearly explained about Illusion.
I have only one difference, and that is, Objective Reality is also an Ignorance. When you said about Quantum potentiality, there is actually "Change" and "Energy" there, but not a steady. Quantum is subject to Waves and Change and based upon a 'Gross Space', which is also a kind of Matter. If this 'Gross Space' is removed too, Quantum cannot be seen.
If one says, Objective reality is a subtle kind - which is not experienced as "Gross" - then it shall be not Ignorance. But, the Quantum researches everything is bound to Space and Waves here.
When one observes upto the length of 10 to the power -34 (planck length) - it's Quantum. But beyond this length, Quantum is also Doomed. When particles are stricked upto this length, observation happens. But beyond this length, even waves are not observed, a Black hole emerges and the particles are swollen and Black hole disappears by emiting Hawking radiations. Even this hawking radiations are experienced because of Space-time. When this whole Universe goes into this Quantum and into the Black hole, there will be no trace of Hawking radiations too.
Quantum is Space-time. Relativity is Space-time. Time and Space is Matter (Manifested Prakriti - as I see it) And Space-time is Doomed (Prof. Nima Arkani-Hamed - School of Natural Sciences at the Institute for Advanced Study in Princeton, New Jersey).
Edit - Above, all I explained about Quantum Field. But, if you speak about Quantum Potential of Bohm's, I have a different view about that as "Objective Reality" too.
Quantum Potential cannot be experienced. Quantum Potential (Can be like Avyakta), but can be experienced only as Manifestation in power of Maya (Vyakta Prakriti). Only Quantum Field can be experienced, but not Quantum Potential.
The Quantum Potential, cannot be an object. One might know, what happens in future, in which position the electron will be, as a knower - Purusha, but this knowing is by accessing the future experience/time of Quantum field (like Time travel), but not knowing the Quantum Potential. But as an experience, only Quantum field can be experienced.
Space is required for any Object to experience. Space is an aspect of Duality. as One experience the other. Without Space (even the Bliss is filled in Space, Bliss is Prakriti too an experienced object but not the nature of Purusha. Bliss manifests first at the time of Interaction of Purusha and Prakriti. Bliss is Brahman but Bliss is not Purusha and Purusha is only the experiencer), no experience can happen.
