Alright, I want to make it clear to both you and me. To me you don't exist, you're a faceless creature. I wouldn't expect you to think any more of me. How are you to know that I exist? How are you to know I'm not just some android typing this down. Now if we meet in real life you would believe I was real, right? You can see and touch me I'm real, right? I should believe the same about you, right? I should, yes I should, but as expected I don't. See how am I supposed to know if I'm delusional and I'm not creating you? How are you supposed to know that you aren't the only human? What if none of this is real, just a figment of your imagination? What if you are the last human alive and you passed out and your mind created the perfectly fantasy world? Now your reason for this being false might be something like why would I want all these problems? I have an explanation for that too, see our problems nowadays are pitiful and nonexistent to your future self and in some ways you enjoy them. You find your current life simple and ideal and all you ever wanted. There is another question that arises, why won't I wake up? Well maybe when you passed out you died, so you won't ever wake up. Honestly there are too many faults to this hypothesis for it to be valid, but it still brings up the question, "What if?"
