Fact or a lie?

Do you believe in ghosts? Have you ever heard terrible stories of spirits that haunt old houses and scare people at midnight? I know a child, whose story might scare you. She did not believe in ghosts until that day, when she was at her grandparents`s house. Sarah went out to play in the street /in front of her house/ with her friends and suddenly she saw a car driving without a driver. She was frightened and began to cry. Sarah's friends fled and left her alone. The car was very fast and Sarah was so upset. Then she closed her eyes, but minutes later she heard a loud sound. Someone knocked her over. She opened her eyes and turned around. Then she saw a white light. She was frightened, but someone or something said her, that she should not be afraid. It was quiet. She asked what happens. Behind her there was a shadow of a woman and the silhouette disappeared quickly. Sarah returned to her home and told her grandparents what was happened. And they did not believe at first, but then helped her. You decide whether ghosts exist or are fiction ...
