I believe that anything is possible only to a degree that you are allowed. your Mind will not let you transform yourself into a machine because you, yourself has never in life experienced what it feels like to be a Metal object without density. You know what try it out and I can promise you that whenever you want to feel or reach out to touch something while you are lets say a Washer Machine I can gaurantee you will still feel your Arms, hands etc... And chances are you will still see them. In your mind you can think OH YEAH!!! Im a Toaster... But when you look around and visualize your hands they will always be there. Because your mind is tricking you into thinking that you are a Coffee Pot when you're really not.
