This happened about 6 months ago on Louisiana Hwy 57, just outside of Dulac, a little town in the bayou country of Louisiana, and while it sounds like an Alfred Hitchcock tale, it's real.
An Ohio businessman, Saul Rubins, abandoned his disabled vehicle on the side of the road, and attempted to hitchhike. The night was pitch dark in the middle of a thunderstorm. Time passed slowly and no cars went by. It was raining so hard he could hardly see his hand in front of his face.
Suddenly, through the sheets of rain, he saw a car moving slowly, approaching and appearing ghostlike in the rain. It slowly and silently crept toward him and stopped. Desperately needing a ride, Saul jumped in the car and closed the door. Only then did he realize that there was no one behind the wheel and no sound of an engine to be heard over the rain.
Again the car crept silently forward and Saul was terrified, too scared to think of jumping out and running.. He saw that the car was approaching a sharp curve and, still too scared to jump out, he started to pray and beg for his life; he was sure the ghost car would go off the road and into the bayou and he would then drown!
But just before the curve, a shadowy hand appeared at the driver's window, reached in and turned the steering wheel, guiding the car safely around the bend. Then, just as silently, the hand disappeared through the window and Saul was alone again.
Paralyzed with fear, Saul watched the hand reappear every time they reached a curve. Finally, scared nearly to death, Saul had all he could take, jumped out of the car, and ran to town..
Wet and in shock, he went into Schmoopy's. Voice quavering, he ordered two cups of coffee, black, and then told everybody about his supernatural experience. The room became silent and everybody got goose bumps when they realized Saul was telling the truth and was not just some drunk. About 30 minutes later two Cajuns, dripping wet, walked into Schmoopy's and one says to the other,
"Look, Boudreaux, ders dat idiot what rode in our car when we wuz pushin' it in DA rain!!!"
