My backrooms nightmare

Part 3

They finished blocking the door and the teacher stared walking up to the front desk in front of us, the big screen in front turned on to a white screen with black figures and distorted shapes flashing on the screen with classical distorted almost broken music playing in the background. The lights dimmed until the screen was the main light source of the room, everyone was dead silent with only the broken music filling the room with noise. I looked beside me to the person and they had the look of fear in their eyes, they looked straight at me and put their index finger to their mouth in the motion to stay quiet, i understood it immediately that i had to be quiet so i slightly nodded and stared back at the screen. The teacher was making rounds walking around the desks checking everyone, then suddenly a person to the other side of me started whispering to another student-mannequin and the teacher-mannequin immediately noticed and ran up to them, grabbed their hand, and marked their wrist with a black X.

The person started crying yelling that they didn't want it but after the teacher-mannequin marked their arm they did the same "stay quiet" signal by putting their index finger towards their face, then continued to walk around calmly. This made my breath quicken as i started to panic but then i looked back at the person i trusted and they gestured towards their chest telling me to stay calm. And so i took a few breaths and calmed my mind, i thought, as long as i don't speak, i will be fine.

After some time only 3 people spoke and i watched as they each started crying and panicking but i remained calm and silent, i focused on just listening to the music and that seemed to ease my thoughts. Me and the person i trusted where fine so far and that got me relieved. Then suddenly the teacher-mannequin came over to me and a random person a few rows ahead of me and gave us a black pen, i knew immediately that now we where both in charge of marking the people that spoke.

I walked around a bit with no one talking so far, but then i heard a slight whisper from the people that sat against the wall and they where giggling, they where human. I walked up to them and gestured them to give me their arm as i had the pen in hand, 2 of the started yelling at me and insulting me and they refused to give me their arm as 2 others where giggling at their insults. I panicked as i tried signaling them to stop talking but it was no use as they just continued to mock me more and more, i didn't want the teacher-mannequin to notice what was happening so i forcefully pulled the arm of one of them as they struggled to get their arm free, i shakily drew a X just like the teacher-mannequin did and let go of their arm. They started yelling at me again but this time they where crying as well, i had no idea what the punishment was for having a X on your arm but i knew it wasn't good as this was they way they where reacting.

I finished marking the rest of their arms and walked around a bit more checking if anyone was speaking or not while remaining silent. Then while i was walking towards my seat i heard a huge BANG noise... it was coming from the blocked door. It sounded like something big outside has crashed into it. Everyone froze in place, even the teacher-mannequin, we all starred at the door as it stayed silent for a couple seconds, then another loud bang sounded at the door again. This time i figured what was happening, they blocked the door to keep a creature out.. and now its here.. trying to get in.
