Zombies or Infected?

Date: 8/15/2019

It all started as a field trip to a medical school. I was with a group of people that I didn't know well, but we talked a lot. They were cool people. When we got there, everything was fine, until a teacher mentioned something about a infection. Somehow, the virus was free and one by one, the people that I knew were getting infected. They were like zombies, expect they had a bit of an conscious. I almost died three times, but something was preventing me from dying. The first time, I was going down the elevator, but one of the infected continuously pressed the button and it crashed. Lucky, the roof didn't cave in directly on me. A boy helped me out before the elevators doors closed on me, but it ended up closing on him, cutting his arm off. I helped him wrap it. Later, we went to play Lazer tag, but I don't remember why I didn't want to play. Scared, I took the elevator up to the 57th floor. When I made it, I saw another boy becoming infected and manged to escape before he could reach me. As it went down, it started speeding up to the last floor again, but I was saved when I tried to go to the floor beneath them, but then, he made the elevator go up and I started to fall, but I laid great. But I think I killed someone though.
