Your mind is too weak, you say in your head. You cannot break free.
But, by some miracle, your mind begins to clear at the same time as the fog covers your mind. You're fighting whatever is happening to your mind, and winning! Eventually, the changes to your physical form are complete, but your mind is still your own, although changed, at least to accept what has happened to you. To a point. Hey, at least you aren't panicking!
Your body is now the shape of a quadrupedal dear. Your arms and legs are now simply your legs, your hands and feet now hooves. You have a dear's tail, and your head is in the shape of one. You somehow can still speak, but you have a feeling what you are speaking is not english.
What do you do now?
