Dream of person

First, I seem to be in a gymnasium, but I am at some sort of theater camp. We have some fun during the day, and I leave to do something. The bleachers are very steep, and when I come back, I fall down the bleachers, but end up okay. I don't feel too worried. We continue some more, and suddenly I am in this odd room that I can't really describe. Someone who doesn't seem to have any particular gender shows up and begins to talk about how every so many years "they" reset all reality and that all of us would basically cease to exist. During this I kept thinking "what if I don't want to cease to exist?" The dream never specified who exactly would do this all the previous times. There is a lot of stuff that I don't really remember after that. Later, still in that room, the person has this red device that is sort of T shaped. The stem of the T is a handle, and one of the other parts shoots sparks. It seems we are now in a void and the person is about to throw the device into the void. This will reset reality... And then I am holding it, and the person seems to be flying off into the void, and in order to catch him or her, I believe I must throw the device at him or her. I wake up then.
