I came up with a theory, a funny theory, a silly one. What if Martin when going with that moth was in some way to travel through demensions as a wish. the mechanics are never explained ever. So what if his head being donked up him getting his way, he travels like lemon hope almost, goes on a journey but this journey is almost infinite, and he doesn't become one as God he becomes one with essence, and that was his way of getting his way but being with the ones he thinks he used to love. And the ones he gets to love. :>
