That sounds reassuringly familiar OP. Strangely I'd never considered that anyone else would've experienced this. After a bereavement I went through a prolonged period of bad mental health, and would regularly see myself from above and behind. I actually found it strangely reassuring, though I was obviously rather mentally ill at the time. I treated it like a first-person shoot 'em up computer game, where you can be full-screen, and see directly out of your eyes, or zoom out behind your character so you can better see the baddies hiding behind the corners. Life at that point was so terrifying that it was comforting to zoom out and try and avoid the bad stuff coming along the track towards me. Fortunately, my mental health improved greatly through hypnosis, and I haven't experienced this strange phenomenon since.
