Existence

This post might get a tad deep, I'm not sure yet. So to balance it out, watch this at the same time: 
Now you should be ok whatever happens. (Except I've find this song twice and twice it has been removed for copyright claims and the original here doesn't allow embedding. But at least it shows that the copyright bots read my blog. But if you don't listen to the village people at the same time as reading this you could have a crisis)
Anyway, for the last few weeks I've been having an existential crisis. I questioned reality, the universe and what thought itself is. This was ok for a couple of weeks and the crisis was more a benign niggling at the back of my mind, until suddenly it hit me on Thursday. We are completely insignificant beings in a massive universe, unable to have a relevant impact on anything. Even if we had access to the entire universe, managed to rule it, then would we have accomplished anything relevant? What is it relevant in an existence that might include other universes, or infinite nothingness? If a person had an infinite amount of time and space and simulated every atom, or sub-atomic particle, in the universe with stones, perhaps taking a trillion years to simulate a millionth of a second, but doing it anyway, how would that simulation differ from the universe we live in? How do we know we don't exist in a simulation? If a simulated world is experienced in the same way as a true one, what is experience? If we experience the universe merely by processing information chemically, then why do we feel real? What is self? If a computer processes data, does it experience the universe? If you are questioning the universe, how many rhetorical questions can you get away with writing? These questions, except the last one, are genuinely things that plague my mind. These thoughts rendered me quite unresponsive for about 2 hours (though I did manage to do an English lesson at the same time. And they say guys can't multi-task). During the journey home things got a bit weird. I decided that my thoughts were too abstract to express to myself in words, so I started thinking in music to express the flow of emotion and ideas. For some reason this put me into a semi-conscious state where I drifted in and out and occasionally started having light hallucinations. It was all a bit bizarre. Anyway, by the time I got home and listened to the end of the longest tennis match in history, I had gotten over the worst of the crisis, but it still niggles in my mind. The only way I've got to avoid falling into total shutdown is by remembering that if everything is irrelevant then the fact that everything is irrelevant is itself irrelevant.
Anyway, if that has caused any of you to have a crisis, watch this video: 
Also I'm writing this before the football, actually at 3 in the morning, so I hope this hasn't further depressed you if we didn't win, or drop the mood if we did. But either way, more village people can't hurt.
Oh dear hell I'm prescribing village people music to fight depression. Someone please make me a manly spotify playlist to balance it out, I think I have issues.
