My partner gets these very horrific and vocal night terrors almost weekly. He yells loudly, "HELP!" When I've tried to wake him, he's grabbed my wrist rather aggressively or slapped my face, all because he's not awake and takes my actions as a threat. He thrashes around, trying to fight whatever is in his dream, and once on vacation kicked a shelf off the wall that was approx 4' above his bed, then got a huge gash on his shin. He just deals with them because he's had them for as long as he can remember, but it seems like there must be something causing these? Does anyone have any insight on this? I haven't had much luck researching on my own. Thanks!!
