We had a motion controlled light in the same home that was designed to turn on the upstairs [2nd floor] lights when your head broke the 6th stair from the top landing.
There were plenty of times when either my wife or I would reach the top landing, lights on, and see a mist or black shadow travel down the hall, or feel a presence pass us in the hall.
Or have my daughter wake us in the middle of the night to tell us that the 'man' would not stop singing.......
