I think this is the mammoth mother of all abstracts. What's real? i wish i knew. how can anyone be sure? surely, most people think they know whats going on. But i wonder sometimes, what if we're all hallucinating? the human brain, as complex as it is, is capable of creating its own reality. People that suffer severe shock or have other medical dilemmas, sometimes hallucinate. Now, how can we know for sure that those people arent being shocked out of hallucination. maybe they are seeing things as they really are. maybe mainstream ....
