<human>: Can you summarize the given text in a few sentences?

Hi all, my boyfriend broke to me this morning that he is very concerned about the things I am allegedly saying (or rather screaming) at nighttime whilst I am asleep. I have been having violent recurring nightmares a few days a week, which involve me crying and screaming at the top of my lungs to the point of him and his parents waking up. I say things like "don't hurt me", "get off of me", "go away" and other things of a similar nature. He comforts me best he can when I am having these nightmares but it takes ages for me to get over one. I don't have any recollection of these nightmares when I wake up. He is concerned as this has been going on for some time now, he says, and now I am too. I have no idea what could be bringing these nightmares on. I haven't been through anything traumatic recently, that I can recall. What should I do?
<bot>: I have violent recurring nightmares on weekly basis, which I have no recollection of, where I scream things that suggest I am being hurt/assaulted etc.
