I was sitting in class when the fire alarm rang. Peacefully, everyone formed an orderly line out the door, making their way outside and towards the buses. The sky had lit everything in crimson.
The sunset glared god-rays through smoke that seemed to rise from the nearby toilet block. On the right, standing over the students and staring emptily was a tall, black-robed man in an unpainted white mask.
I heard screams emanating from the grounds. High-pitched screams, followed by the rev of a chainsaw. Everyone was silent, staring at the school. We eventually got on the buses and I woke up.
