I've thought about that a whole bunch of times in different ways.
Ever consider the idea that the true reality is either super advanced technologicaly or nearly destroyed by a super advanced war and the denezins of that world escape the boredom/horror or their lives by playing a game where they live a life in this reality.
Think of the Matrix without the war against the machines part.

Also I've had the thought that our civilization is merely a science experiment for some kid from an alien race that is so advanced that we cant even really comprehend them.

It is fun to think about (especially while stoned), but it is mostly pointless unless you're wrighting a novel. So get to work cause hollywood is running out of fresh ideas
