Navel

To see your navel in your dream represents your being and self. The dream may indicate that you need to find your center and middle ground. Alternatively, to dream of your navel signifies the bonding to their mother. 

To dream that you or someone has a navel piercing denotes your deep connection with your mother. Perhaps the dream is telling you to reconnect with your mother or that you need to be in touch with your maternal instincts.
