I had a dream last night that started with me on a college campus sitting in a classroom. Me and a bunch of others were getting some sort of training--it wasn't immediately clear to me what we were being trained on. We threw on some gear and went outside to choose our weapons. I picked something up and started walking around the campus. I walked into one building and it was all immediately clear to me...we were fighting off zombies that had invaded the campus. I had ~50 or so coming at me, so I ran outside to draw them into the open/towards my fellow zombie killers. They came out and we started kicking some ass...I was killing them by hitting/stabbing them with something. Some of my group members had swords, guns, flamethrowers, etc. This went on for a while until I paid attention to what my weapon was. An olympic barbell.
