Shared dream

<PERSON> I was in what looked like some sort of conference room, but it was at a school. I was one of the only people sitting in there. I was waiting for a friend to come meet me for lunch. I talked to them on my phone at one point. Then, I got on a school bus with many other people who were around my age, some a bit older. I was sitting on the left side around the middle, when I noticed a guy that was sitting up front. He was holding a black gun. Was I the only one who noticed this?! This could not be good. When the bus started to move, the guy with the gun started to fiddle with his gun, talking to the guy sitting next to him. He then put the gun up the the guy's bald head who was sitting in front of him and pulled the trigger. It clicked, but nothing happened. He did it again and again, and another guy, a tall guy who looked like maybe he could do something about this situation, stood up and started examining the gun as the gunman held it. "What is this?", the tall guy said as he pulled out some sort of pin from under the barrel. Then, it was done. The gun worked. The gunman shot the man who helped him. Then, for some reason, everyone had to move up to the front of the bus. I moved by climbing over the bus seats. I was sitting by the window next to someone, I am not sure who. I then saw the gunman had gotten my best friend, <PERSON>. She was wearing a dark green shirt and was laying face-first in a bus seat across from where I was sitting. I could not believe this was happening. The gunman then approached me. He put the gun to my head. I squirmed right as he fired, so the bullet only scraped my head instead of going in. It hurt when this happened. I then woke up for a minute, and went back to sleep, entering the dream again. I was on the bus again, and we were all filing out a door in the back of the bus. I was chaotically trying to get out, and in the confusion, I ended up having to climb over the handrail that was by the stairs. By the time I was finished doing that, everyone was already off the bus and gone. Well, everyone except for me and the gunman. I ran as fast as I could, but I was exhausted from climbing all over the handrail. The gunman caught up with me and grabbed me. He no longer had a gun, but a knife. I tried to get away, but to no avail. I asked him to please shoot instead of stab me, but he just laughed. He stabbed me, then put the knife to my neck as if to slit my throat. I was dying, I could feel it. I could not escape him this time. Then, I was with <PERSON> somewhere. I was talking to her about what had happened, and how it had been a dream. I told her that the man did actually slit my throat (when I am pretty sure he was just preparing to). I also said something about my middle school. After I finished telling her the dream (with those couple of extra details I just listed), she told me she had the exact same dream. I was excited to post in AND the fact that we dreamed the same thing in my journal on Dreamviews!
