By the way, the business about the jaw is usually what I call the Life Will trying to take over, but because you are aware of it your are frightened and block it.
In life and sleep we have two powerful actions working in us. The first is our waking experience based on having a body, its limitations, vulnerabilities and a particular gender. Our second is the power that gave us life and continues to express as dreams.
While we sleep our conscious self is largely or totally unconscious, and while we sleep our voluntary muscles are paralysed – so another will or motivating force moves our body. So we have a Conscious Will, and what I will call a Life Will. The first one we have experience of as we can move our arm or speak; but the second will takes over when we sleep
This Life will can move us to speak, to move our body, and in fact do things that we cannot do with our Conscious Will. As Freud pointed out this inner will has full access to our memories. It can do so many other things that are described else where.
This Life Will or motivator has been active for millions of years and we see it working all the time in animals. We are partly split in half because we are often opposed to what our Life Will in us wants. So the only way to express what is good for us is in dreams when our conscious will is largely passive.
Life Will created your body and pre-existed you as a person you know today. It was working in you prior to your ability to speak or know in the way you do now. But of course it has fantastic wisdom and skills, as can be seen in animals.
As the life will causes all the spontaneous movements of your body, so when you are passive and usually asleep it tries to release tensions and heal you. So if you relax and allow it it will start this and you can witness it in a wonderful way. Allowing it consciously is what I call http://dreamhawk.com/approaches-to-being/the-lifestream/
