A part of my nature is wolf - its not another persona, not some role play character, its not a spirit guide. It is not "pure" wolf either, and I don't expect to be able to shift into a wolves mindset - in the same way I know I'll never be able to shift totally into a human mindset. However the mix of these two sides varies. I haven't figured out why yet, although it is often coincident with a change of mood - not really sure if one causes the other or not. I don't know if any of it is affected by the moon - I like bright moonlit nights, I'll sit and watch the moon, and I can feel closer to my wolf side, but I can sit in broadleaved woodland in the middle of the day, or pad across frosty grass at dawn, and feel just as close.
My realisation began when Reference.com mailed me the first 50 lines of the alt.fan.furry FAQ in response to a query about something entirely non-furry. I downloaded the whole thing because I was curious (and to verify that it didn't contain any of my keywords - which it didn't). It then didn't take me long to find the alt.lifestyle.furry FAQ. A whole range of ideas and values that I had been struggling with as separate issues finally had a focus, a name, and *others* had been there before. I had found a new home. Thanks to some crosspostings to alt.horror.werewolves I have now found that is isn't what I would have expected, and there is another group of kindered spirits.
I'll still continue to think of myself as furry (meaning furry lifestyler) I guess until I can really pinpoint the difference between the two groups.
Understanding my true nature has been a very liberating experience. Before I've had to rationalise my "behavioural problems" as the result of childhood influences, resulting in a lot of bad feeling towards my parents. Now I know where I stand its actually seems easier to interact with "mundanes". Where once stood a socially inept human now stands a furry with a gift for a foreign language. Altogether I'm a happier soul than I was. Friendships with my own kind have given me the self confidence to interact socially in the mundane world.
I've had Dreams and lucid dreams where I have been an anthro-wolf, and one instance where myself as an anthro-wolf was transformed while running into a true wolf. Being able to run on all fours was an exhilerating experience. As a child I used to have Dreams about being a dolphin, but I have yet to explore that again. I've had a couple of shift experiences where I feel like I have an anthro wolf body (I'm sure it wasn't a physical shift as I was in a park at the time - somebody would have noticed ;), but no change of mental state. Until someone comes up with a better terminology, I'm going to continue calling it a sensory shift (thanks Locandez).
The whole set of ideas is still very new to me. I'm so busy trying to understand what furry/wereness means to me, that I haven't even had time to think about why I am this way. That is another journey which I have yet to begin. Thanks to my new friends I have also begun to explore my spirituality too. All in all its a process of realisation and integration.
