The canine teeth of humans are not considered fangs, but in vampire mythology these teeth are elongated and are that creature’s tool for extracting the blood he or she needs.
If some animal, fictitious creature, or other human being is exposing fangs to you in a dream, you may be expressing fears of being dominated and consumed in some way.
If you are the one who is sporting fangs, you may be expressing a voracious appetite that either needs to be expressed or is being expressed in the world.
If the former idea resonates, look to where you can increase your passions.
If it is the latter that feels true, you may be hurting others with your words or actions. [1]
A feeling or fear of someone intruding on you, crossing your boundaries, compromising your integrity, or attacking you (physically, emotionally, or mentally).
A feeling or fear of a person or situation “getting under your skin,” perhaps with a lasting effect (as an animal bite can lead to an infection).
