If only someone could tell me...

Reality comes and goes. When its gone it is replaced by something similar and impossible to distinguish until its back. Our minds have the ability to comprehend and accept the most ridicules scenarios. We realize its not possible for individuals to suddenly become someone else only when the reality that we weren't in replaces the one we were. If we didn't fear insanity to much we would easily be able to adapt to any change in atmosphere. Although stuck in our ways by the necessity of nature and the urge to survive, our subconscious proves to us in alternate reality our will to survive also necessitates the ability to adapt quickly to new realities. Now If only someone could tell me, why are the walls are moving?
