Plague doctors shot up my school

Date: 2/22/2019

I had this dream a couple of weeks ago. The first thing I remember is that I was in a school cafeteria, i was the only pupil in it. I looked to my left and the tables/chair never stopped, it was an endless row. I looked to my right, once again it was endless. I panic as I hear gunshots behind me, I look in front of my and see a door to the kitchen (the kitchen spans the entire width of the cafeteria). I look behind me to see the silhouette of a plague doctor with a shotgun in his hand slowly approach me. I get up and sprint for the kitchen, I get in and lock the door behind me. I press myself up against the door as I quickly catch my breath, I look to my left to see a figure wearing a plague doctor outfit standing next to me, however the beak part of the mask was chopped off near the start and it was covered with a lacing like material. Giving it a unique and horrifying look. The plague doctor broke eye contact and looked towards another wooden door, I hesitantly walk through it. It leads me into my own backyard. Another plague doctor stands there, same sawn off beak. He stands there lifelessly for a few moments before leaping out at me. Waking me up
