Why do I keep dreaming of wolves?

If this were my dream, I would try to ask them what they want, who they are, and what they have to tell you. In dreams like this they can speak if you speak to them. I would say that they are appearing as totems to send you a message. There's a reason they keep appearing.The setting is primal, a snow covered forest. This sounds like a Source visitation, a message from your deeper knowing self. How did seeing them make you feel? Anxious? Glad? Perhaps you need some of the power these animals possess. Their traits, like strength, family values, loyalty, team players, the ability to see in the dark (see what is unseen to others).

Just a guess.... you are being given messages by the aggregate of creative forces that will only in time work their way into your psyche with understanding.
