Sharp Jaw in dreams
The lower bone of the face — the hinge of speech and the muscle of held tension.
How sharp changes the reading
Sharp texture adds edge — the symbol has a cutting side. The base reading still applies, and the dream is asking you to hold the symbol carefully because it can hurt if handled wrong.
The base reading of Jaw
A jaw in a dream is the dream's image of the hinge where speech is produced and where held tension settles. The jaw is one of the first muscles to clench when you are trying not to say something. The dream brings the jaw when there is a piece of unspoken material in your life that the body has been holding for a while. A jaw relaxed and moving is the dream telling you the speech is finally available. A jaw locked, painful, or wired shut is the dream noting that what wanted to come out has not, and the body is paying for the silence.
