Need tons more data... Are you sleeping somewhere new? (Apt, hotel, new house, etc) Is it the same bed? How old are you? (Nothing specific, like 14-20, 20-30, etc as age is a factor.) You could record optionally if you have a camera. Waking up a few times, you might be able to catch yourself and see what happens. From the description, sounds like you have some form of sleep talking. Good idea is to try to think of the dream you just had and recall everything that happened. Dreams are thought to have some connection to real world scenarios. Maybe an interview bothers you, so you are running through them. Possibly a teacher or peer who you need to interact with. Even something simple like general talking in public to strangers. If you have a insurance plan, you should be able to call a doctor toll free and ask about it. Disclaimer: I am not a doctor.
