I was in a house with dozens of other people, I'm not sure who they were. I felt sick, so I went to the toilet, however the only toilet available was in the room where the crazy dude was. I went in there, but I didnt get sick. Somehow I pissed off the crazy dude, and I knew I needed to get out. When I got out of the room he started banging on the door, everyone in the house needed to leave now.
Everyone ended up leaving, and going to some field. The crazy dude was hidden within the group, he had a gun. He started shooting randomly, a few of us were playing dead. There was a little girl beside me, I dont know if she was shot or playing dead. I could see him aiming the gun just above my head, he knew I was alive.
I couldn't let this go on for much longer, I quickly got up and grabbed his gun. It was a small pistol. I didnt really know how to use a gun, but I had to try and shoot him. After 6 rounds he finally had a bullet hit him, I and the remaining people alive ran to the next town over and begged someone to ca 911.
