this morning i was standing on the stage with the lights off ,i turned around for literally 15 seconds and when i turned back around the lights were on at about 10% .here comes the spooky part, no one was in or around the booth and even if they were it takes longer than that to unlock two doors, climb the stairs find the booth light switch and turn on the board. that is just the first thing, i was cleaning up on stage to get ready for the first band rehearsal and i found the dimmer racks open, the unusual thing about that is no-one in the building has a key,only the av technician who's office is at another school has the key to it, he had not been in the building in the last couple of days P.S. i did my dimmer checks to see if they could not get enough air or were just messed up, the checks supported the theory of something weird happening without any human interaction!!!!!!!!
