High School Problems

It all started as a normal day at school, I guess. And then suddenly a guy named Martin was killing everyone in the most violent ways possible. I don't remember exactly what he was doing, but I know there was a lot of blood and it terrified me and another girl. We climbed all the way to the top of the school to get away from him, but he eventually got to us, and he killed her. For some reason, he let me go. Later I went to look for cover, and I found a bunch of other women hiding out in a bathroom. I saw there was some space next to two women on a bench under a blanket, and I begged them to let me hide with them, but they refused. Eventually, another women told me I could hide with her. She was a black woman in light blue clothes who looked like a body builder and was honestly kind of scary, but I was desperate, so I took her offer. She was really nice though, and we shared her blanket, which we hid under. Later she got up, angry, and punched a stall nearby, saying she hated the way we were forced to live in hiding everyday and couldn't go anywhere or move around. At some point, Martin and the woman who was in charge and looked an awful lot like my head boss at work, came into the bathroom looking for us. She shot pretty much everyone else and then found me, and she put a gun against my forehead. It was cold. Martin told her not to shoot me, but I figured this was a better way to go than torture. Just one bullet and I would be dead after a few seconds. Very little pain. Just as I thought she was about to pull the trigger, I heard another shot and felt the gun lightly hit my forehead before the woman with it fell over to reveal someone else. I fled the bathroom and attended a meeting of sorts. There were tons of chairs, but only the first rows were full, reminding me that everyone else was probably dead. I don't remember anything that happened at the meeting really, but I remember I went up in front of everyone and brought up what had happened to everyone. I said something like "look what they've done to us! Look what they've done to Martin!" Apparently he was short at that point so I picked him up and hugged him. After the meeting he made me leave because apparently there was something (or someone perhaps) that was inside of him and controlling him and he could change at any minute. I ran away again to a different bathroom hide out. This time I hid in a corner behind an extremely large bench with another woman who I think may have been one of my old high school people who I still have on Facebook.
I don't know if this part is another dream or a continuation, but I was outside in a very green place with grass and trees. I was being forced to remember some silly code so that I could pass a class, and we were required to watch a certain yaoi anime show for that class. All my friends thought it was hilariously awesome that the school was making me watch anime. I tried to find the episode where they recited the code but was having trouble, so I went and found the paperwork in a folder with some paperwork for a sewing class I was taking. I felt like trying to memorize this code was pointless and much too difficult, but I had to try because apparently my mother was counting on me.
