you can' physically transform into a wolf, it's not humanly possible, it's a fictional concept. originally it was used by terrified people in the dark ages who lived near woods to explain how a wolf could appear and disappear suddenly, killing livestock. now, it's used to enchant and mesmerism peoples imaginations.
it could be your animal spirit, or spirit guide though, again, this doesn't mean you'll turn into a physical wolf or wolf-human hybrid. Your spirit guide is just that, there to guide you in tough situations. in Native American culture there's a coming of age ceremony around 13 where one finds their spirit guide. each tribe had different methods, but the results were through a vision or set of circumstances the animal would reveal itself to you.
wolves are a very common one, a lot of people love their mystery, admire the pack qualities as well as their appearance and what they represent. if you wish to learn more about a wolf totem to see if it speak to you, i'll include a link to a site i like:
remember though just liking an animal doesn't make it your guide. you should try meditating near the forest on the question 'who is my spirit guide' while not always physical [normally it's a vision] the animal should appear.
