Who's to tell me what this ought to be? A projection of my inner memory? Who's to say this isn't a dream? And that real life isn't what it seems? Who's to tell me there's more than that? I might just be a brain in a vat What if I'm just dreaming? You can 't prove anything - Impulses I'm receiving - that says I'm anything! Who's to say that night makes your mind rest? This might just be a psychological test Who's to say that you're nothing but an illusion? A projection of myself, or maybe a version? Who's to say that reality is clear? When the unreal might be experienced as real?
