J'essayerais comme cela:

A group of students was touring the UK. They spent one night at a very old hotel in Scotland that looked like a castle. One of the boys was not able to sleep. The door of his room opened and a mysterious lady crept in. The boy was playing games on his cell phone when suddenly he saw the lady sitting on his bed, close to him. She was very beautiful, but there was something strange about her. The boy realized she was not a real person, she was a ghost. He was so scared that he fainted. The following morning his room mate had a lot of trouble waking him up. At breakfast he told the other students his story and they made fun of him. The hotel owner, however, confirmed that there was indeed a ghost in the castle and that the boy had been lucky enough to see her. The students shut up and the boy felt vindicated (or very satisfied).
