I think about that stuff too! It makes my head go round. It all started when I was five. I thought if I could just look back quick enough I would see the world wink back into existence since I figured out that the world might just cease to exist when there is no one looking at it. Weird I know, and I have no idea where that idea came from, but it popped into my little mind and from then on, I continued to think about weird things and even scare myself silly sometimes
