Night-terror In Jail with Outlaw Bikers--Bloodbath Ensues

I'm in jail, or maybe just a concrete box. There are some pretty bad guys in there with me--1%-er outlaw bikers, who I'm aware want to do me serious bodily and psychological harm. There's a bunch of them. When they come for me, I'm so terrified and ready to fight for my life that I somehow escape serious injury (it just wasn't a part of this one), but the dream won't stop (night-terrors are like this sometimes; you never wake up when you get too scared, like you would in a regular nightmare). I punch and kick and bite for a very long time, and finally I've actually ripped them to pieces with my bare hands, and I'm covered head-to-toe in blood, but the gore keeps coming at me because it's still alive and malicious, and I reach the horrifying realization that I won't be able to destroy their ill-will. I wake up in a pool of sweat, so terrified that I can't move. Summer 2010.
