Eve Graveyard Escape

You're a writer and you often come to the old cemetery, where you find it easier to think. You do not believe in all sorts of evil spirits and ghosts, and even more so in effect they receive on Halloween. In the evening, you decide that you need some inspiration, and you went to the same cemetery. But when you come, they were frightened, as the cemetery gathered evil spirits. They closed the entrance, and now you're trapped.
