The boy stared out the window, his eyes wide with fear. The moon was full, and the shadows were long and sharp. A dark figure was moving across the roof of the house opposite, and the boy knew that it was a vampire. The vampire was coming for him. The boy's heart pounded in his chest as he watched the vampire approach. He knew that he had to do something, but he was too afraid to move. The vampire was almost to the window now. The boy could see its fangs gleaming in the moonlight. He screamed and slammed the window shut. The vampire let out a blood-curdling howl and disappeared into the night. The boy was safe, but he knew that the vampire would be back.
