no noise, no lights, aircraft was hovering above my parents house without making any noise

My neighbor had dropped me off at home,  she looked at my parents house and ask me what was on top of our house.  I walked around the side of my house.  There was a huge craft hovering above their house.  I swear it did not make any noise.  No noise-like aircraft noise.  No engines, no lights.  It was a full moon and my parents lived out in the rural part of town.  I started yelling for my Dad to come out.  When I started yelling for him,  the thing took off so fast.  It was gone before I knew it.  It was a full moon, no clounds.  I have never seen anything like it since it happened.  I do know the difference between a aircraft, ballon(weather).  Helicopter.  This was something else entirely.
