This is part of my quickwrite in Mr. Sutherland's class on spirits. I also added examples that I thought of in books and reality. I said that spirits are emotions like happiness, anger, revenge, and so on that can control you in a way, like impulses and choices on split-second decisions. I have many examples that they are true.           
          In the book Unwind, one character named Conner had some problems that he talks about. He would often get in fights for no reason at all because there would be too much noise. He would just turn around and beat someone up.
          Another example (though I'm not entirely sure it's a true example) is the main character from The Curious Incident of the Dog in the Night-Time Inn, Christopher. I didn't read the book, but from some of the discussions I heard, Chris couldn't control his emotions and didn't know how to deal with them. That could be because he has so many spirits in him and they are all happening at once, so that he doesn't know what to do.
          Possibly even some people who have anger-management issues have a lot of anger spirits in them. You could call those spirits demons I suppose, and maybe things like meditation or that whole take a deep breathe stuff tames them in a way. Maybe some people write in journals ore diaries because they can think about their thoughts and know how they really feel. Kind of like with siblings are angry at each other and say "I hate you", then they probably don't mean it. Saying that, like swearing and yelling and punching stuff, lets out anger. Also things like being distraught and not eating or doing things that keep you unhealthy are ways of the spirits that have sadness show emotion. That's all I can think right now. I might think of some other examples.
