When I was in Karachi I heard a lot of ghost stories.

The most famous supernatural incident was the one that use to happen on a Road in Defence. There was a famous story or incident floating around in Karachi circles. 
Several people had claimed to have seen her. She was beautiful , she wore a white saree and ... she was Dead. 
Many people told me the same thing. While driving through Defence near Abdullah Shah Ghazi Mazar they were stopped by a woman asking for a lift. She was beautiful and wore a white Saree. Her hair long and black blowing in the Karachi Breeze. It was near midnight. The person asked her to sit in the car and she told him to drop her to her house. She even explained the address in detail. When the person got there however he saw that the front passenger seat was empty. She had vanished in to thin air. Obviously disturbed the man aproached the house which the woman had described as her own. An old man answered the bell and said " 
I am sorry You must be another one . You see My daughter was killed by her husband and on this road and since then she comes to haunt it " . The man was terrified and drove home in a state of panick. 
Now this story was really famous in Karachi when I was there. But the strange thing was that I heard it from 3 different people claiming to have had the same experience. 
I remember that road it was near the graveyard and had a strange feeling when I passed it. 
Though I have heard many stories I have never seen or had a supernatural experience. Are these old wives tales ? 
I would like each and everyone of you to tell me one such incident that you believe to be true. It would be intresting to know how many of us have seen or heard of something like this. 
Thanks
