In my old high school there was a room that was used for lectures and had rows of seats going up about 20 levels high (like a cinema) with a tracing machine in the middle at the bottom, four of us were doing some tracing work with all the lights off and just the light of the tracing machine, when we were talking about ghosts/Ouija boards etc and from nowhere a poster tube got thrown from the top of the seats down to the bottom, no-one else was in the room with us as we instantly ran for the light switch and looked in the rows of seats. I was never sure if this was a prank or not, but the look of fear on everyones face doign the tracing told me it wasn't them.
Another one we were at a school trip to Bradgate park when we did the foreign exchange program with kids from Germany, we were telling them about the ghost of Lady Jane Grey. As it was a horrible day only a few of us got off the coach to go into the park, when we got outside the castle ruins there was a loud clap of thunder and the heavens opened on us, we turned round and in the distance saw a white figure standing on the ridge, when we started running away and turned back this figure had gone. Not sure what it was at all, but it scared the life out of all of us.
There are a few other weird/creepy things that have happened to but the details are too long to write up.
