The concept of dreaming could actually be imaginary and may have been a memory from you past life, in fact every dream could be a whole life time. Metaphorically speaking 90+ years could have been condensed into 8 hours of subjective time. It has been said that there is no possible way to alter time but what if instead of altering it you created a parallel timeline with the potential to alternate the history, specifically yours and the history of the other peoples lives that are included in you life. This means that every time you die in this dream/timeline you kick start a parallel timeline, so that you once again are given another chance to redeem yourself. But where is the limit? Who is there to judge whether you have manipulated the timeline too much? Will there be consequences for manipulating the timelines? Is there ever going to be a time where you create a timeline which causes you to never dream again? By dying are you entering yourself into an infinity loop of timelines? Is there ever going to be a timeline where you become immortal and are trapped in this dimension or timeline for eternity? All these questions I will try my best to answer as I progress and develop my theory.
