I went through a bad spell several months ago where I was having horrible nightmares that were causing me to react violently in the outside, non-sleeping, real world.
When the zombies were attacking me and pulling me down to my doom, I woke up to find myself kicking my wife. She did not appreciate this.
When the gangsters boarded my yacht and where about to start cutting off appendages, I flung myself off the boat and woke up on the floor next to the bed. I did not appreciate this.
When the troll was trying to bite my face off, I woke up to find myself stabbing the nightstand with my eye glasses. The glasses miraculously survived but the top and front of the nightstand are all gouged up.
At that point, I collected all the blades, Surefire E2Ds, and firearms that were within easy reach of my side of the bed and put them far away to avoid doing anyone or anything some serious damage.
Fortunately, that wretched time has past and I'm sleeping like an exhausted puppy again.
