It's not regular, but on occasion I will wake up kicking or punching in bed due to a dream of a self defense type situation. I looked it up and it's known as "Rapid eye movement (REM) sleep behavior disorder." I'm not sure what causes it for me, but it makes me worried that I might injure somebody else or myself in sleep. Curious to know if anybody else has experienced this and what they did about it, before talking to a Doctor.
I don't know if this helps but frequently I will thrash in my sleep, sleep walk, or mumble. Sometimes I would wake up terrified, I got diagnosed with sleep apnea and the doc put me on trazadone as well. I've noticed alcohol, stress, and eating too close to when I sleep makes it worse. Seen some improvement with the trazadone
I was 17 on spring break in honolulu and hooked up with a 24yr old booze cruise director. Coolest chick in the world. She had a studio apt. on lewers. But she had like 5 or 6 other people staying there paying their share. Very awkward. Two were a boy girl couple early twentys on the floor sleeping. All of the sudden the guy starts slugging his girlfriend in the shoulder hard. You could tell he was angry. She kinda starts doing a muffled cry but then they both fall back to sleep. Then Kathy says, thats ok it happens all the time, he doesn't mean it. That was 36yrs ago and one of the craziest things ive seen.
