Mystic or UFOs? (3 photos)

The case occurred in the United States, Illinois. The woman went on a completely empty highway.
Feeling a slight bump in the left side, she quickly straightened the car, and wanted to look in the rearview mirror - but saw nothing !!! She stopped, got out of a car - and was horrified at what he saw !!!
The whole machine - is a solid deep dent, but there is no trace - the paint in perfect condition, there is not a scratch, nothing ...
