Like I said, that's not even the main reason.
To sum it up in one sentece, I'm convinced that this world, no, reality in general, is all a massive fraud, that nothing we can see or feel or hear or taste is real, that there's something inherently intangible beyond all of it...
That was one very long sentence, and even it doesn't do my little philosophy justice.
Random thoughts...uh-huh. My brother and I, back before we hated each other, had a game where one of us would say the very first thing that came to mind, and ther other one would blurt out the first thought that popped up as a result of the first, and we kept going until one of us said something that the other just couldn't come up with a response for. I'd win frequently. Obviously, a game like that wouldn't work nowadays.
