The Dark Figure

It was midnight. All students were in their classrooms learning.A window shattered from in the hallway, followed by a piercing scream. The school fell dead silent. Outside my classroom window, a dark figure was standing still and silent. I could faintly make out two red fiery eyes.The dark figure broke into the classroom...

Panic. Screams everywhere. I dart to the nearest cupboard and hide. I peer out of the crack in the cupboard. I see my chemistry teacher- Miss Noodlebottom- she was so afraid of death, but now the dark figure is ripping out her guts and chucking it at all the other kids.

A while later I see the figure up more closely: two fiery red eyes, sharp, pointy teeth with blood dotted all over them. It sort of looks like a zombie but much more slender and agile. Josef, someone on my table, was hiding in a cramped cupboard on the other side of the classroom. The zombie started creeping towards the cupboard I was in! I was about to scream but then I heard Josef bang his head on the cupboard door. The zombie dashed towards Josef, grabbed him by the collar and flung him out of the window. I could hear him moaning
"Oww... the glass its... AHHHH!"
The zombie was upon him again munching on his brain like a human munching on a banana.

Morning. I must have slept in the cupboard that night. I was about to step out of the cupboard when I heard footsteps, so I stayed still.
It was my best friend Farharn. But then... I saw the zombie.
Farharn shouted abusively at the hideous creature.
"You're a chubby chicken! You ate my friends but you won't eat me!"

Farhans body is scattered all over the floor. A book from in the cupboard I was in fell. The zombie was on top of me in a flash. I'm trying to push his face away from me but he's too strong. I give up and watch my life flash before my eyes.
