Suggest Treatment For Groaning Loudly In Sleep

I have been moaning/groaning loadly in my sleep latley. I was never aware of it (as I thought I never had it) untill about two months ago. My friend slept over my house and recorded me sleeping. It was the most embarrasing thing that I have ever experienced. I then slept over at a friend's house last night, and she too said I groaned (I immitated what it sounded like on the recording, and she said that is what it sounded like.) I did some research and I think I have Catathrenia? If im wrong, what do I have? If Im right, even if Im wrong, how can I be cured? And by the way, I am a fourteen year old female.
