When I used to train martial arts seriously, I often would wake up finding myself executing a joint lock on my pillow or something similar. I had to move my bed away from the wall to stop me from punching holes in it. I was always terrified that I would injure my girlfriend at the time, but somehow I seemed to limit myself to inanimate objects. I stopped training about 10 years ago and haven't had a problem since. Other people have told me it is actually quite common.
Wow, I have the same experience, and the very same misgivings! Good to know it's common, and probably not dangerous! Thanks for the information! :)
At least one person (Kenneth James Parks) has been successfully acquitted of murder, and the acquittal later upheld by a Supreme Court, based on such a defense.
I've got sexsomnia. Unlike sleepwalking I'm not at much risk for injuring myself, but interactions with bed partners are less than ideal. It's led to some uncomfortable situations, particularly when I was younger and didn't know it was an issue. Thankfully low dose benzodiazepines knock it down.
