"horror" story

I had an idea for something on this website. What if we wrote some "horror" stories that we came up with and get each others opinions on it. you could make it reddit style if you want to or you can do it in whatever style that you want to do it in. I'm gonna attempt to write one as an example and see what you guys think of it.

This morning, as I was walking up the stairs to my second class of the day, something strange happened. I was about to approach the door to my classroom's section and the lights flickered. It was pretty normal to me because they usually do that on the daily but this time, something was off. I turned around and noticed that everyone was gone. That's odd. The bell hasn't even rung yet. I continued to walk to my class and noticed that the door was propped open by the trash can. Uh, ok. I guess the teacher is at her desk right now. I opened the door to see that my classmates were in their seats only to find out that they weren't my classmates. They were complete strangers. I tried to ask what was going on but I got no response. They all seemed kind of. Off. I decided to head to the teachers desk to ask her what had been going on but she wasn't there. That's odd. I went to go and sit in my seat but I noticed that everyone was now staring at me. They had weird smiles on their faces. "Um, what's going on?" I asked. Instead of a response, they contorted their faces in a way that made them look inhumane. Then, they all started chanting something. My brain told me to get out of there as fast as I could. Before the thought could fully get out, I sprinted out of the room and decide to look for somewhere to hide. They were all starting to slowly chase me down the hall, Gradually getting faster with each step. "Nope, Nope, Nope!" I sprinted for the door. Once I got out of the room, I heard a muffled walkie talkie and some keys jangling coming from down the hall. I ran towards it thinking that I could get some help. I ran as fast as I could towards the sound. As soon as I turned the corner, it disappeared. "What the he-?" I exclaimed. Before I could finish my sentence, the nonhuman strangers continued to walk towards me. Their legs twisting in ways that I could DEFINETLY tell that they weren't human. Luckily, there was a door leading to a stairwell down the hall so I immediately ran towards it and made sure to lock it so the "things" couldn't get to me. I ran down the stairs and found a bathroom nearby where I am typing this now. If you see this post and I don't give an update, Just know that they have somehow gotten to me.

Update: I have gotten out safely, thankfully. I started to scream when I saw one of the "things" crawling under the bathroom stall towards me. It scratched me on the leg and I crawled up onto the the toilet to try to get away from it. Two staff members heard me screaming and came to investigate where the noise was coming from. I tried to tell them what was going on but all that came out were incoherent noises. They looked at each other in confusion. I started to cry and they led me out of the bathroom to the front of the school where they called 911 so they could address my wound and try to get more information on what was going on. 

What do you guys think of the story? I might add some more to the "Update" part but please let me know what you think in the comments.
