The hitchhiking ghost of Kentucky

A friend/work acquaintance of mine had a ghostly encounter driving the backroads of Lexington Kentucky when she was a teenager.  She was driving with a group of three of her friends late at night through a dark wooded area.  They passed an old church with a graveyard (this is not abnormal in Kentucky, in fact most of the older/historic churches here have graveyards) when a woman wearing a Victorian dress flew out into the middle of the road in front of their car.  You could tell she was a spirit, and you could tell by the design of her dress that she was from a different time period.  She was wearing a white dress.  She looked right at their car and started screaming and then flew into the car with them and right through them.  My friend and all of her friends started screaming and quickly drove out of there.  She never went back on that road or researched the area because it was a traumatic experience for her.  I did go back to that same area with a group of my friends to investigate to see if we could figure out her ghost story.  It does have a very creepy feeling there at night and one of my friends in our group saw a white mist above our car while we were driving through that area.  We never figured out who the apparition was, but Kentucky does have a lot of haunted historical sites in that area.
