Allegedly, spirits of those who have fallen victim to automobile or road tragedies, spirits that haunt the very location where they were killed.
Phantom hitchhikers are some of the most 'popular' type of ghosts worldwide.
The typical story usually tells of a lonely driver at night on a lightly traveled road, who picks up a strange hitchhiker, drops him or her off at some destination, then somehow later finds out that the hitchhiker had in fact died months or years earlier often on that very same date. Some say they are apparitions, and some say they are nothing other than spirits repeating time over and over again. One that goes into the car after stopping the driver. These are just waiting by the side of the road, usually of the opposite sex. One that gets hit or nearly missed by driver then no body is found.
