Dream About School Dispenser Sword Confusion

My dream took place at one of my old schools when I was in 9th grade (not too long ago), where there seemed to be a new extended area that was a part of the school that doesn’t exist in real life. I noticed some of the seniors walking towards something I was unfamiliar with, something like a dispenser of some sort. They found an object next to it, like a shiny blue orb, and walked away with it. Once I approached it, I found a sword that was from it, and I walked away with it. One of the teachers confronted me about it because there were security cameras at the dispenser. I got in trouble because I was told that only the seniors were allowed to take objects from it, in order to complete tasks. I was scared and confused, but I was still curious about it. I honestly can’t remember anything else that happened in that dream, but at one point in a different dream last night, I went to the Heartland Humane Society, which is an animal shelter that I used to go to camp at when I was younger.
