Well, from my experiences, my hands have never been really deformed or anything.

Once the only thing different was that one hand was smaller than the other.
Another time, my pinky and ring finger were bent back so that I couldn't see much of them and when I tried to turn my hand, they would just curve more around my middle finger so that I could only see one side of each finger
Yet another time, I looked at my hands and they were perfectly normal, although shortly after violent vibrations shook the entire dream and I woke up

Those're just my experiences
