The building I work in is very haunted, was a slaughterhouse back in the 20's-50's. Im in the building alone a lot & hear doors slamming, footsteps & voices, music coming from rooms that are empty, see dark shadows moving out of the corner of my eye. A guy I work with wants to spend a night in there with our girlfriends, couple other buddies & their spouses, video cameras & voice recorders. My girlfriend is all stoked & ready to do it but Im hesitant. I dont want to provoke anything at all..........I gotta work with anything we stir up! I see & hear enough crap in there as it is!
