I'm not sure why I'm such a dreamer. I was just thinking a moment ago how I would love to run outside. Just open the door and run. I just got out of the shower and my feet are soft from the water and I imagined what the cold earth would feel like under my feet, but then I thought. I'd get more enjoyment out of dreaming about running, then actually running.
Maybe it is because when you dream of running, there's no chance you'll fall.
