I see what you mean but I fail to see how it actually applies. We glorify oursleves by implying that we do not exist simply materiliastically. You're separating humans from the rest of the species in this world simply because we can think better or do you think that this 'after life' applies to all the animals along with humans?
I would say it applies to all things. They are saying that we are right now living in several invisible worlds parallel to our own human world, with the only difference the quantum wave properties. So I guess the implications are that something conscious, animal or human can continue being conscious after death in another one of these realities.
I've also read something about dreams, how they can only be explained as experiences from another parellel universe, dragged back to our own. The reason they are sometimes so weird is the other universe differs so much but our mind has to explain them by its experience in its own universe, so they often don't make sense. So it's not that we are fighting monsters in the other universe while we are asleep in this one, that's just symbolic explanation for what we are doing and seeing.
