In addition to the post i put on zzxxee's thread, when i was at high school in London, a local girls school nearby was said to be haunted, as it was built partly on an old graveyard site and still had the main cemetary next to it.
One evening, we got into the science lab building, as the window was left open, to carry out a ouija board experiment, as one of my mates parents had one, in the part of the school that was said to have had apparitions/voices and strange noises coming from it.
Anyway, there was 6 of us............3 girls, 3 boys.........we got in ....had a torch and it was reasonably bright from the moon and light from streetlamps from a nearby road.
We set up the ouija board, put our fingertips on the planchette, and started to ask questions like...."is there anyone from beyond that wants to come forward"..............well, at that point, almost straight away.....................the cupboard behind us with books, papers, general stationery items etc just started shaking uncontrollably......................so we did the only thing we could!............ we screamed and ran for our lives..............it was me that had to stay the longest in there to pick up the board and all other evidence that we had been there, and it was still shaking violently when i climbed through the window.
We never did anything like that again.
Do not get involved in ouija board's..........there's something about it that's just not right.
