It is a fact down here in Hawaii that each school has it's own ghost stories. May it be a dead nun, night marchers, or a spirit that follows Janitors around, no school doesn't have something going on. The High School I go to has even been published in a book due to a well known haunting in the schools dark room (well, it aint there anymore but it was well known). But that makes you stop and wonder, are there more? Well, guess what, not all spirits like being kept in the dark so to speak. Their existence lost because they aren't as famous. A girl watches people from the window in D building but vanishes when you look back, a friend described to me one night at school what is called an Obake Neko (ghost cat in Japanese), something walks around the boys locker room at night (and begins banging the door when someone gets too close), and a couple of kind old men walk around the campus at night with a vacuum (except the school doesn't have anyone working at night or room cleaners at all!). Pretty freaky huh? And to think, I have to go there everyday. There's more stuff going on there than at any graveyard I've visited. At least in the graveyards I can run but when I'm in school I can't exactley run out of the classroom screaming (I am such a chicken when it comes to this stuff). Anyway, I've experienced all this stuff first hand so I'm not lying. As for my friend, he doesn't even know what an Obake Neko is but his description is scaringly similar. So ladies and gents, any spirits you can't avoid? I have more but some stories can wait.

I taught school for eleven years and have heard numerous ghost stories about several. I only taught at one school that was haunted and it was a pretty interesting experience. The school was in a small East Texas town, and was tiny. The year I taught there, we had 11 students in the graduating class!
Anyway, the school had a reputation of being haunted. Reportedly, it was built on an old slave cemetary. About 10-15 years prior to my coming there, the fellow who had been the superintendent had murdered his wife. According to rumor, she was buried near a tree outside my classroom. I did check this story out, to my knowledge, the guy is still doing time in the state prison.
The year before I taught there, the ag teacher had been chaperoning a school dance. He had wandered into the auditorium and saw a woman in a white dress glide across the stage. Thinking it was a wayward student, he followed in an attempt to round up the culprit. She vanished right in front of him. I never had the opportunity to meet him, but I would have loved to have heard his story first hand. I learned of the tale from other teachers.
I experienced a few things myself while I was there. Mainly, books flying off the shelf when no one was around. We pretty much took it for granted our ghost just wanted some attention!
Schools see a lot of strong emotions, so it stands to reason that some of that energy is left there as an imprint in the fabric of time.
