I have a question regarding my meditation. Since more than 3 years, after my first vipassana (Goenka) retreat, I have the feeling that my face is moving, twisting. Sometime if I feel more relax, all my upper body is twisting. Does anyone have an idea of what is it?
Thanks for any advices
Besides just being a hallucination you should not follow but just let it be, facial twisting feeling might be an indication of teeth-grinding at night. By talking to a few meditators who also grind their teeth while asleep, I've come to understand that certain twisting, tingling and cramping feelings on the face aren't just hallucinations but your facial and jaw muscles actually relaxing or contracting. I've been told a few times that my jaw is visibly clenched on the other side while being extremely relaxed on the other while meditation, producing a kind of semi-paralysis impression for a bystander. I don't notice this myself as a pain, just a twisting feeling on my face. The looks aren't everything, but obviously an unconscious clenching of ones jaw is not a good thing either.
In case you do suffer from bruxism, meditation probably helps, but consulting a dentist might be a good idea. In my case a dental splint has made things much easier.
