Considering all the things that have entered my head... I have no right to call anyone weird about their own thoughts and personal fantasies. We all have something, but few of us are so willing to admit them as you have. ;o
Edit: One thing I do have that I will admit though... is that sometimes, when I start wishing I was someone else, or at least look like someone else, my mind starts believing it. I almost feel as if I am someone different for a moment, and my mind sometimes even tricks my vision into seeing things in a different light to reflect my assumed persona. At the same time... these "new beings" mostly relate to my face rather than anything else. This does not last when I look into the mirror, but otherwise it is a very interesting experience.
Sorry if that description is a little... vague.
