What does it mean if you dream of wolves chasing you and while you are turning your head to see them they have these faces of some people you know then their faces go back to that of wolves?

This dream is interpreting itself! The wolves represent people whom the dreamer feels are enemies. Because dreams generally provide information that the dreamer does not yet know on a conscious level, it is likely that the people appear at first to be friendly. The subconscious mind may have picked up on subtle information that the dreamer has ignored with the waking mind. Now the subconscious mind is using the dream to say very clearly that these people are a threat.
