Why do i constantly dream about car accidents?

Its been a few years now, possibly just a bit after i started driving, since ive been having numerous, hundreds of dreams about car accidents. As time goes on, they seem to get more and more frequent. At this point i have at least one dream almost every night about wrecking my car, or getting pulled over for reckless driving because i lost control of my vehicle for multiple ludicrous reasons such as not being able to break, or running over a pebble which propels my car into an insane spin over multiple lanes of traffic. These dreams always seem incredibly real, sometimes i even feel pain and always wake up frightened or disturbed. I've always had lots of very vivid and phantasmagorical dreams ever since i was a child, and maybe it would help if i said that i tend to be a very paranoid person, always worried something unrealistic may go wrong. But this car accident thing is really taking its toll on me. I really want to go back to dreaming about things other than wrecking my car or getting pulled over for something out of my control. Does anyone have any suggestions or insight?
