yup im on the old graveyard shift, there we are 3 of us sitting at nurses station sitting discussing ghosts and deceased patients and the likes, when all of a sudden we hear the phone ring, we answer, there is no-one there, so we put it down, and ring the number that gives you the callers number, it only turns out to be one of our mobile (cell) phones ringing! She checked it in her bag and sure enough it was dialling out...by itself...in her purse!!! explain that! we were mystified and TERRIFIED!!
