Field trip trauma

Date: 9/29/2019

For some reason my school was going on a field trip to a nuclear test site. We went through this security building with our car when we came in and these military people showed us around. Suddenly one guy says "run!" so I start running but the people who were farther away from the guy have no idea what's happening so I try desperately to breathe and get a word in, I calm down enough to whisper "bomb,run" and she shouts it to everyone. I go around this large building that had a ton of windows into a larger space and a man is a bit away but he throws a bomb towards me and it immediately starts smoking. I run faster and most of us get away but I don't know what happened to the rest. We get back to the lot where our cars are but another military guy informs us that there might be an active shooter in the lot or in our cars so we have to drive back to civilization in a big tour bus. We all file into the bus which has bunk bed like seats that are see through like glass or plastic, and duck just in case the shooter might come towards us. Suddenly the same military guy that told us our cars weren't safe comes onto the bus and tells us we can go in our cars after-all because he checked everything. I was so relieved because I had left some valuables like my phone in the car. We drive out of the lot and into the security building to get checked out, suddenly everything starts closing and I realize that we have to get out and stop the doors from closing so I run out of the car to the side entrance of the building and just nearly hold it open. I instruct everyone else to make sure every last person gets inside the building and then I run for the next doors. I also realize that it must be the shooter trying to stop us from getting out of the test site. Two of my teachers grab guns from dead security guards and go in front of me, we run down halls until we finally hear someone running around behind the door in front of us. We open the door and the shooter comes at us, he kills one of my teachers but the other one pins him and I grab a gun and shoot the evil man. We run around the building again knowing that it is now safe, but suddenly my teacher trys to open a certain door and red lights start blaring and sirens come on and doors start shutting again so I race thought the doors with all my classmates and I just grab the last one that leads outside before it closes. The end.
