I would agree with the Hooligan. Reality does not exist per se, but rather is percieved. So whatever we (either as individuals on drugs or collectively sober) percieve is in fact reality. I hate to bring up the ol' Matrix reference, but really, how do we know we are in fact not in a simulated reality, or the only conciousness that exists is actually my own, and the world was created in my mind as a self defense mechanism against the trauma of that realization. Oh hell... I don't know what I'm talking about.
