A round Ball OF Light 20 feet above ground 2 field lenghts away from my car

This has changed my life .
my girlfreind and I were driving from my fathers place in Southmountain east by Brinston Road toward Inkerman, on our way to Winchester to our Appartment, when I looked to the north in a field where i used to play with my friend as kids .
2 field lengths by the old windmill I was shocked I thought a Hellicopter had his search light on for a plane crash or somthing, so I pulled over and shut of my 1971 Duster and just staired still not believing what I was seeing A round ball of flouresent type light about the size of a silo roof, it was not like a plate flat it was round ball of light, like looking at a small Moon kinda light 20 feet above ground I then looked at my girlfriend and her jaw was just hanging ,not saying one word , I asked her if she was seeing what I was , because I still could not believe it! she still did not answer me this would have then be about 11:05 5 min just stairing at this roun ball of light no sound or any noise at all quiet night then all of  sudden it started to move directly toward my car , Im now getting goose bumps typing and thinking back to when It happened 23-4 years ago i Freeked at this point Looking at it comming right toward me , I tryed to start my car and for some reason I could not, mabe to nervus or it I just couldnt move my hand I then came with in 100 feet of our car very low to the ground and shot right in the sky less then 5 seconds on a clear night please I hope you understand i am telling the truth I never mentioned this till 2 or 3 years ago no one would believe it I was afraid I listened all that night to all radio stations  but not one other sighting was ever heard if this is of help to any other person I wish I could remember the exact year and day, i could try to contact my old girlfriend she does live near by But the time was 1978 to 1981 or so
