Possible Soul Exchange? Options

Hi guys, I'm new here (IMG:style_emoticons/default/smile.gif)
I would like to ask, would it be possible if I want my soul to be in someone else's body. Have you heard of walk-ins? Is there such practices/ritual for this? Hope to know more

@ Fatherjohn: Do you have a list of recommended reads you would be willing to share that cover or work up to this concept of center of reality? Unfortunately I have not encountered this with my own astral work, but it seems to be such an advanced state that few would fully achieve it. But your points are convincing enough to make me interested in learning more.

@Eria: With magick, the ability to achieve specific objectives are the result of comprehending and applying more general and abstract concepts through personal experience. But maybe that's not always the case because I'm in this thread with more questions than answers myself.

I'm surprised because if this underlining magick allows the magician to do basically whatever then that would mean many other particular branches of magick would be less useful, like working with goetic demons.
