talkin while asleep

About four times a year my wife will do the strangest thing in her sleep.
She starts saying no, no and then goes into a deep voice and starts talking in a strange
language that I never have herd, she says the same thing over and over it will last for about two minuets. The first time it scared the living **** out of me, one time I got up went out side to see if there was a UFO around. She never remembers doing it and thinks I am nuts when I tell her. This has been going on for 30+ years. Beam me up Scottie !!

Wow! I'm wondering if it happens about the same times every year or is it random times. Also, if you could record the language and see if anyone can translate.
