Sacred Haven of Debauchery

I had a dream tonight. I don't know what it was about at first, but then we split into groups and fought... At first, we just had a squad, and then we split into groups of four. It's a shame I don't remember anyone, but the guys were interesting. Each one was different, and they all had special abilities. And at the end, I don't know, it was like I was alone against everyone. It was in some kind of school attached to a church or for the sick, I don't remember. We were running around there, shooting at each other, and then we went outside.
