If you dream of having abnormal number of body parts, it might mean you’re having an identity crisis. For example, if you dreamed you had two mouths, you could be talking much more than your usual self. You could be eating more than your usual diet, or you maybe drinking more than your usual self. This dream alerts you to the change. Your brain wants you to think about what could have caused the change. If you knew about the trigger, you could also think of ways to manage the stimulus.
