Do any of the muslims have true jinn stories?

I have heard a few from my friends. One friend told me about the time when she and her cousins were sleeping at night. She was suddenly awoken and she saw her sister in the doorway just standing there. She got up and asked her what happened, but her sister didn't say anything. She told her sister that she should sleep as it is very late in the night and they both came inside the room. She lay back down and closed her eyes and drifted off. In the morning she got up and asked her sister what she was doing at night. The sister had no idea what my friend was talking about. She had been sleeping the whole night. This really scared my friend and much later when she narated it to her mother, she was informed about jinns inhabiting the old house.
