Traveler, I cant really be sure whether or not its a bona fide condition as i have not been monitored in a sleep lab, but i know that my wife wakes up at least once a week. I have noticed in the past that it is directly related to stress. When i was young i noticed everytime i had a hard day at school or had a test the following day i would tend to shout or talk alot in my sleep. I think it would be safe to say that i sleep talk and move in my sleep at least 3-5 nights out of a 7 day week period. I work in a very stressful environment and find that it can get the best of me in my sleep. But thats just a hunch. I know that if i can reach REM which is a Theta/Delta phase i know i can project. So like you were saying i should definitely try some Trance/meditation/Energy conjuring and phasing.
