Beneath the masks

Everything's black and only fear runs through my veins. He/she/ it is chasing me for a long time now. My legs can't stand the pain.
Running in what it seems to be a barn, I see a dark hallway and without hesitation, I run through it. On halfway through, I turn around just to see that it is not chasing me anymore. It dissapierd. Then, just when it seemed that everything was over, I turned around to see that It was in front of me, pointing a knife towards my head. It was wearing a mask, so I couldn't see who or what was it.
I couldn't talk. I couldn't even move because of the fear. The feeling of knowing that you're doomed paralyzes every inch of your freaking body. It just stood there, doing nothing. I couldn't stand the idea of dying, so I started to run.
