My True story is this.. my first nursing job was a very small rural hspital, -which is now shut down- sometimes we had only 2 patients , I worked a lot of nights, It would be me and another RN in house, it was 2 floors but the botten level was like the kitchen and storage, ect.. there was an elevator, often, at night between the hours of 2-4 a.m the elevator would just come up from the basement ( 1st level) to the 2nd, no one on it, no one down there, the door would just open, ( we could hear it coming if we were at the nursing desk) ) and then the door would open and then about 10 minutes later or so , it returned the way it came up. It sent goose bumbs up the back of your neck! and also sometimes around 3 a.m the phone would ring --no one there--just dead silence. This happened about every 3 nights. weird!!
