When vampires transform, there really isn't a whole lot that is bodily changed like werewolves. For instance, a vampires face goes through an amazing transformation. The angles of the cheekbones get squarer, leaner, and stronger. Angles of other features also get more alligned, and the face sort of takes on a look of a predator, the eyes narrow and really everything just gets more sharper and scary looking. I have only had that happen to me once, and I even scared myself. It's something that nobody really wants to experience, because then you get bad dreams for the rest of your life.
