At the end of night full of kinda crappy dreams, this was the finale. I was with a girl I dated in the early 90’s. We were at some kind of school dance in a weirdly laid out gymnasium type room where the elevated stands took up like half of the small court area and almost reached all the way widthwise across to the other wall and kind of half blocked the one entrance. She and I saw this girl in the stands in a bright blue sort of puffy Cinderella-esque dress pull out two razor blades with a malicious look. On that cue, several other girls in matching dresses of different colors pulled out razor blades too.
We retreated toward the door and found that some others had already found it was barred shut from the other side. As the razor girls came toward us, I grabbed a metal folding chair and swung it at the hands of the girl in blue hoping to disarm her and tried to retreat more. At that point I wasn’t sure what happened but it appeared that they had been overwhelmed by the rest of the crowd in the gym who I presumed had taken them down and got control of thing.
Next scene was my girlfriend and I laying on a bed in the corner right by the entrance to the gym as the Principal stood by the doors as someone unbarred them from the other side and opened them. I said “That’s pretty unsafe only having one set of doors in or out!” She agreed. My girl and I just laid there on this random gym corner bed recovering from the ordeal.
