You awaken, if only for a moment from your unconscience state. You're not sure why at first, but it appears the changes have, if only for a moment, stirred you from your weak state. You feel your ears changing, growing and lengthening, even as they become long and ovular. Your tail bone aches as your tail grows longer
The area around your legs and crotch begin to itch, even as you begin to grow distinctly possum like fur in that entire area. The same fur grows across your back, and across your face. The most dinstinct thing to happen though is your face, which begins to lengthen and grow long, into a muzzle. Your canine teeth become longer and more dangerous looking as well.
The changes aren't entirely negative though, even as you feel many of your own wounds begin to close up, as the effect of growing new tissue is causing them to heal up, leaving you in a much better state than you were.
The ordeal over, you feel yourself slowly slipping back to sleep again.
