What happens when our brain dies, subsequently decays and stops sending and receiving electrical signals? Does your theory only make sense if we are considered "God" only while we are alive or do we remain "god" after death? Do I continue "tripping" after death and DECAY or do I start experiencing through the "eyes" of an atom or subatomic particles? Do I get reincarnated as suggested by some?  Does my awareness shift to the awareness of some other being?  If you have answers to these questions I would indeed say you are using your imagination. You could look into Ian Stevensons research though but I would like it known that the brain is processing information and using that information to make decisions without "your awareness". I'd let that sink in for a bit.
