I too had a frightening dream last night.
It started at school, where it was refurbished into a school of magic training(dreams make no sense, this is a good example of this). A big artificial lake runs through the lobby, with big "power gems" surrounded by steel grating and bridges running above the lake. For some reason never explained, the whole of seventh grade goes into the auditorium. I practice a little magic, and take a seat. On a table lies a red cylindrical machine with two barrels. Something that was never shown caused me to get out of my seat and take a run for it. I take out a gun and shoot at the threat, but I hit the machine instead. The machine fires a volley of rockets, one hitting a kid and blowing her into a million little pieces. At this point, I'm too mortified to move, whilst the other kids evacuate. When I ask a teacher just why the hell we have an automated rocket launcher in the middle of an auditorium. He says it's for "security reasons".
I wake up, scared, and force myself back to sleep. The next dream I had is about how I found a kitten in my basement :3
