The search for the cause of my non-idiopathic RBD led to a diagnosis of MS as the root cause of the RBD. An MS lesion on my brain has caused atonia to stop functioning when I am dreaming. My body has the ability to move during REM sleep. I have punched, kicked, run into the wall, carpet burned my knees, yelled and cursed, etc in my sleep. Many of these dreams are still vivid to me years later. I would like to connect with other people who have the same condition. I have met only a handful of medical practitioners who have any idea what I am talking about.
