In general:

Everything in the dream, what represents the wild, is untamed. Part of the dreamer resists to any kind of control. It is the part of himself, which must be free and is creative and independent. A wild animal embodies the aspect of dreamer’s personality that has not yet committed to rational thinking. Depending on whether the dreamer is a man or woman, wild woman stands for the anima or the shade, and a wild man for the animus.

Psychologically:

Everything in wild is free from the limitations that society imposed on the people. Therefore wildness in the interpretation of dreams symbolize anarchy and lack of stability. In a positive sense prevails profusion, and all that concerns the dreamer, is auspicious.

Spiritually:

In a dream to be or to feel wild, points to a lack of spiritual mastery.
