i have felt this sensation many, many times before, and the times i did break my soul loose, i had an out of body experience. when this happens for the first couple of times, your mind tends to race when its happening. don't let you mind think !! in other words, don't focus any attention on words or any kind of thinking, do your best to clear your mind. what i do is think of a beat of my favorite song, i reccomend a soothing, slow beat or instrumental.
