Your mind is truly your worst enemy

Your brain is working against you. When you fall asleep, that large organ that is pumping to keep you alive inside your head is thinking (ha ha) of ways to make you terrified. What i'm talking about are bad dreams and nightmares. Every part of your body is supposed to be WITH you, working to keep you healthy and happy. Not your dome, though. As soon as you fall asleep it remembers all of the things that you talked/thought about earlier that day. It remembers all of your greatest fears and all of the things that have recently been bothering you. After it gathers all this important information, it puts it into a tiny film to be shown inside your head that will either terrify you, make you uncomfortable, or make you very sad. Thanks, brain, I thought we were buds.
