Ok, So lately I have woken myself up moaning in my sleep. And a few days ago I was at a sleepover and when I woke up all my friends Said I was making "sexual noises" in my sleep.. So when I got home I talked to my mom and she said. I do it quite often.. So, why am I doing this? How do I stop?

Sidenote: I have a cough currently and wondered if it has anything to do with it
