Dream About High School Dock Police Water Hiding Rowdy Hallways

I dreamt that I was in high school again, and me and a couple other high schoolers drove a car over a dock, and there was a specific way to park the car so that we wouldn't get caught. The police came, and we all jumped into the water, and we had to hide under the water, but for some reason I was able to breathe, and I could see the cops circling around where the water was. And so once the cops were gone, we all snuck out of the water, and we went inside the school. The school was dark and dingy, the lockers were small and gray, some were badly damaged and dented in, jammed so they wouldn't open, and the students' names were on them. Now I feel like I was in trouble, and I had to hide again, but for some reason I hid underwater until the cops were gone, and then I came back up and I went to class. Then all of a sudden, me and all the students were out in the halls, I guess we were changing classes, and everyone was just so rowdy, there was a lot of aggressiveness with the male students, and no one was really in their classrooms at the time, we were just running a muck in the hallways and being very chaotic without a care in the world
