I'm not sure about reincarnation and re-birth.... HOWEVER, I have had instances in the past, when I've dreamed about (my eyes) being separate from (and seeing) my body. I have recently considered whether or not that may "mean" that, in a past life, I was decapitated and my head was alive, sensile for a while, and could look at and "see" my body.... I little kooky, but who am I to say that it NEVER could have happened????
