When you look in the mirror, that is your true form. We are humans. We are on the physical plane. Nothing will ever change that. We're humans that is all we will ever be.
I'm sorry to burst your bubble, but magic isn't fantasy. It's a real thing. There are no vampires like in the movies, there is no form changing, like in the movies. All of that is fantasy fluff. Not everything is possible, unfortunately, on this plane.
