No, rather a compartmentalized sub-matrix designed to entrap the spirit while the physical body rests. This dream sub-matrix is likely similar in nature to the astral realms we go to when the body dies, but it is disconnected from those realms.

All the things you write about are intriguing, but I personally think that the consciousness that created this reality is too smart to be challenged or defeated. Even the smartest of us are like 2 year olds compared to it's infinitely superior intelligence. It has everything absolutely rigged so we cannot escape it's grasp or cheat the system.

I love the idea of being able to quantum jump into other versions of myself residing on another time frame, but, again, it's all rigged so we are nothing but pathetic meat sacks trapped here until our prison sentence is over.

Life is the ultimate Alcatraz.
