Yes my wife does almost the same thing when she goes to sleep if I'm rubing her back or her hair she will jury bad. When I stop she does to. We have asked the Dr's at u.v.a. but they say it's nothing and not to worry about it. I truly think they just don't know and a Dr will not say they don't know and make up something that u don't know what it is. But sorry not even the Dr's at u.v.a. can find our y this happens. They say there the best Dr's in v.a but I truly think its cap best of luck to u
