All that I can remember of this dream is that I was possibly at a college, at some point I was walking through a building where maybe a trial involving a crazy serial killer / spree killer / mass murderer case involving a man or young man with light-color skin was taking place, so I guess it was a courtroom at a college, which makes no sense, and as I walked through the building I guess the crazed murderer on trial somehow got a gun & a knife & he was holding someone hostage.
I walked out of the room as I heard him start attacking everyone, there was chaos & some people ran in my direction, and we ran to escape the building.
