I felt my head slowly swivel downward and to the right, and felt a strange sort of stretching of the skin on the underneath of my chin and my collor bone, as if I were dragging the two together and they were stuck a little and the skin was being pulled. At that point curiosity got the better of me and I snapped out of it to find that my head was in a very comfortable position on the pillow, very slightly back and to the left. The little annoying sensation of skin-stretching remained for a few minutes and then faded away, but I'm certain my head wasn't pushed forward enough to have my chin anywhere near my collor bone. I've read Astral Dynamics pretty thoroughly but I don't think it mentions anything that would explain this. I could be mistaken...any ideas?
