Followed by an illuminating ball of light around 3:30ish am, the closer it got the bigger it got...

I was traveling home on interstate 295 North about 10 minutes from the Fort Lee/Hopewell exit in Virginia. It was between 3:34-3:40am with no street lights on the interstate it was pretty dark.  At the time I was the only vehicle on the road.
I look up to my rear view and notice what to me looked like a vehicle way off in the distance coming over the hill.  Focused back on the road I decided to look again.  From where I saw that light, to where it was then it's just impossible to drive that fast in less than a minute. I'm starting to look closer, it's only one light which then starts illuminating its light in wave like motions around its self. I speed up thinking " This is not happening right now!". I truly became scared as it increased speed when I did...
My focus was distracted when I noticed a vehicle going south.  The illuminating ball of light seemed like it was going to catch my car until the vehicle traveling south became parallel with the light and then quicker than a blank of an eye, the light beams it's self in a perfect line straight to the other vehicle. GONE!  No noise nothing just disappears from my view, the light and other vehicle.
My heart was pounding. I'm coming up on my exit and what do I see? The light is back behind me brighter and and faster.  I increase my speed taking my chances on the off ramp but as soon as my car turns off it zooms by me like it had targeted the next car it could see .
I know what I saw, can't explain what but I can describe it to the T.  Those terrifying images will never leave my head and I hope I never have to experience them again!  My entire life I don't think I was ever that scared.
