I'm experiencing strange sensations in my jaw when I try to astral project. I'm using the Gateway Experience audio tracks. My jaw was shaking like crazy earlier while listening to this - it stopped as soon as the session ended. It was quite a distraction. I've previously had experience with kriyas (involuntary movements) when meditating intensely, and I wonder if this is something similar? Am I just going crazy or has anyone else experienced the same thing?
