Can someone interpret my dream?

My dream starts out with me being at the front gate of my old highschool. Everything was really bright, and all of a sudden my old english teacher tells me to go to her classroom. Thats when a classmate of mine informs me that a school shootout started at the other side of the school. Then, without even seeing who the shooters are, I know that they are all people I know, in fact, they are all old friends of mine. Then my dream goes black and then goes back to normal. The shootout was over and had lasted for 3 days. Everyone is told to leave, go home, and to not come back to class till next week. During the shootout 3 kids died and a few were shot and injured. Also, during the shootout the people involved had forced everyone to take off all their clothes down to their underwear. On my way out of the school I couldn't find my clothes, so, while in boxers and with my backpack I'm leaving the school and am offered a ride from this religous woman that I know in real life. For whatever reason I feel hesitant to go in, but then I decide to take her offer. I go into her car, close the door. Then I wake up.
