DH does this, and sometimes shouts. He does have bad dreams sometimes I know. But it wakes me up - especially the shouting! And I can sometimes struggle to go back to sleep if I wake.
Is there any hope? It's at least every other night and the shouting is at least once a week.
(It's the usual dream random madness - DON'T GO IN THERE or I SAID NO or IT'S ON THE ROOF kind of thing. At least he's never accused me of murdering him, I suppose!)
