i read a story once about a man who was tied to a chair facing a cave wall with a fire behind him. He couldn’t look left or right or even at himself, just the wall. As things went past her saw the shadows of them on the wall. That became his reality, it was all he knew. I can’t shake this feeling that I’m not really here, or anywhere. What are my thoughts? I’m just a vessel for tiny organisms to be transported, maybe my conscience-ness was a mistake? How do I know anyone else can even have thoughts and feelings? What is my reality?
