Alternate Reality project

So I have thought about this all weekend and brainstorming about an alternate reality and the best I've come up with is everything that is normally right side up so instead doing everything up side down; ex: where the floor is on ceiling and the ceiling is on the floor. Perhaps doing an alternate ego or a different you, a you that maybe you would rather be or a you that no one sees and knows about but you; like a proper girl that is secretly mischievous or visa verse. I could absolutely see a person that has suppressed their total personality and it finally coming out seem as a alternate reality. The only problem that I've had with these ideas is that I don't really like them much or either that they are just not fully developed and have no idea how I could make them better and to accomplish them. Seems as though I still have some thinking to do and some bumps to overcome.
