Dream of person

I am in class, doing a school project. There is a girl sitting behind me, I cannot recognize her face but I know I love her. We are talking about a game called Pokemon that we see in a magazine, then I get sick all on a sudden and leave. The next day, I come in and my teacher's stuff is knocked over. I help him pick it up, but then everyone starts going outside for some competition. We have to avoid zombies and the last person gets a prize. I end up getting grouped together with some people I don't recognize, and we start running from the zombies. I see a fenced in grocery store in the school. We go in, and one by one everyone in my group is taken by the zombies. I make my way outside the store and I see the same girl from earlier in the dream. We go together and get to the cafeteria, where I win the competition and get a free pass to do whatever I want in the school.
