Any school based dreams I have tend to take place in some kind of slightly deformed (crazy staircases and what not) version of my elementary school. I'm still in high school and sometimes college in these dreams, but they all take place at my elementary school.
Just last night I had a dream there, I can't remember exactly what happened but something had me running out of the building and down the street.
Another interesting thing about my dreams is that I can have a dream full of monsters and murderers but they'll never be a nightmare, just amazing action packed adventures. The only nightmares I have involve my computer getting a virus.
One dream I had involved me getting a virus that somehow controlled my computer. The virus then spread to the TVs phones and other electrical things and controlled everything. It also spread to the cars at some point and controlled the car that we were in. I can't remember exactly what happened next, maybe it drove us off a cliff or something.
I'm surprised that nobody has made a horror movie about a virus. Considering the electrical age that we live in I would think that someone would.
