The one on the right is from an old dream (as in a few years now), and she (yes, she) chased me the entire dream, those teeth always peering at me from around corners. I never got a malevolent feeling from her though. In fact, I got quite the maternal vibe from her despite her inability to speak. I woke up while running from her. I call her Mother Monster for lack of a better name.

The one on the left is from a more recent dream, and he definitely was malevolent, though in such a manner that it seemed perfectly natural. He was so very cheerful about it, anyways, and can speak. He enjoys the hunt, but loves the kill. He uses those teeth of his to make short work of his victims faces. Unless he catches a woman. He has a special interest in menstrual blood, and gives a whole new meaning to the phrase "eating a woman out". I woke up after he caught me. I think of him as Needleteeth or Sharkeyes.

No idea what he's saying to her, but she looks offended haha.
