The ontological echo hypothesis

What if in the deepest cavities of our sleep, Dreams aren't just fabrications but realms that exist within the structure of our mind, What if these dream worlds are not illusions but real in their own right, revealed by the eye of the beholder, not created by it. "If a tree falls in the forest and no one is around to hear it, does it make a sound?" Suppose that our waking world that we deem to be the "real" world, may actually be a node of consciousness suspended within the mind of a higher intelligence. Just as our subconscious thoughts create worlds incomprehensible, Perhaps we too are created by the thoughts of a mind beyond our conception. This suggests an infinite regress of consciousness, worlds within minds, minds within worlds, existing endlessly like cosmic nesting dolls, each layer believing itself to be the origin, the fundamental reality, yet each is a minor blip in the vast cosmos of a greater awareness. If this is true then is there an origin? A true genesis of a seemingly limitless abstraction? Or is reality simply a boundless hall of mirrors, perpetually dreaming about itself within itself within itself. To be conscious, then, is not to awaken from the dream, but to realize we have never truly left it.
