Either somethings gone wrong, or i've gone wrong.

I had a dream last night in which I was fighting 2 of my friends. They both told me they work for evil or something.

Now 1 of my friends is starting to get into bad habits, such as stealing. Another 1 is just fine.

I just remember fighting 1 of my friends, which was the "just fine" one, who ran away.

Now lets call number 2, "Fork", for now. So I fought fork, and he had some weird boomerang weapon and it has like a hole where the blade is, my sword gets caught in it, but somehow I all of sudden go really fast and shove it in his chest. Fork bled a little, and started stuttering as if he was about to say something really depressing. I shoved the sword further into his chest without hesitation and blood starting spurting. He suddenly vanished and a pool of blood was all that was left of Fork himself. I woke up. Now because I was sick, I couldn't go to school, and I wanted to tell them, right when I got up from sleeping, but I was too sick to go to school, and 2 minutes after I got up and came to my senses, I realized it was best to not say anything to them at all. So here I am, on a sick day from school typing on a keyboard about how I had a dream about killing one of my friends.

If anyone knows why this happened, give me a reason.
