Generally, it symbolizes the relationship between the dreamer and her surroundings.
If it is the muzzle of a domesticated animal, the circumstances are favorable and offer a context in which you feel comfortable and at home.
If it is the muzzle of a threatening beast, you feel distressed and unable to change that which is hostile to you.
If you see yourself with a muzzle in place of a human mouth, the dream expresses discomfort with the image you project to the world.
