Worried about sleep walking. Living alone

So I've lived on my own for 5 months and 2 years previously but with an ex. My ex was toxic and etc. The one thing he told me when we first moved in was I slept walked and would talk shit to him. And I thought ok maybe that did happen cause I didn't like him that much. He wouldn't let me leave the relationship. Then it became he thought I was fucking the neighbor and random people, so he suggested serotonin cause of my sleep walking. Then it became in my sleep I was telling him I was fucking all these people and how much I hated him, and I didn't know if it was true cause I did hate him but I wasn't cheating. Now I'm worried I actually do sleep walk and since I live on my own (thankful for that) I don't want to leave my apartment or do anything dangerous
