I saw two silver/gray objects of different shapes.

I was 4 years old and living on my grandparent's farm in a mobile home situated next to the driveway.  At the end of the driveway was a barn.  It was in the early morning while my parents were still asleep I climbed up on a dresser to look out the window.  I saw two objects sitting in mid-air next to the barn roof.  The two of them together were the same size as the barn. The closest one was shaped like a disk with a round ball in the middle of the top.  The other one was shaped like a top. There were no lights or markings on either.  They were silver/gray and not shiny.  After I realized they didn't belong there I turned to call to my father, and when I turned back they were gone.  Every time I see a picture of a top or the planet Saturn I am reminded of this childhood experience.
Date is approxiate.  We have arbitrarily assigned a date in 1954 so that the report sorts to that year.  Please see entry for July 1954 from St. Louis, MO.  PD
