When my mind sleeps my body often does not, what to do?

So without alarm I sleep 9-10 hours. If less I'm exhausted, like a walking zombie, if i sleep enough that point I'm just generally tired, i can do SOME tasks but get exhausted easily. I've been through a few years of insomnia sleeping 2-3 hours in anxiety, but after I got over my breakup I sleep easily now with my new partner. But he claims I keep moving, punching, crying, shouting, arguing or even trying to waking him up to show him cats playing chess (in my dreams). It's like 5 out of 7 days a week on average. He can't rest well enough, I'm tired all the time so I guess I don't get quality sleep either. I do not know when it started, once even my ex mentioned I cried like crazy in my sleep. What to do with this?
