Explosions in the mind

Those minutes where I'm alone, just me and my pillow. I think, a lot.
I think about everyone and everything, anything. It varies from "What am I doing with my life?" to, "Did I have homework?" The room is so silent, but my mind is so loud. It drives me insane because the things I usually don't think about, I think about. Sometimes, I hate it because it brings up things I'd rather never think about again.
The split second before sleep is the most active moment of my life.
