i could loose those and put it there

What if the Universe was subjective, and we could quite litterally create personal universes, based apon the rules set in us, to a point that our world is our world, meaning We collectivley created the universe we live in. So much so that the world we live in could be re-writen to a point where we can exist in “our own little world” and what if you could generate enough energy behind your new rule, to make it law, or at least temporarily exist?
