There is no "after" as there is no time.
In my view/experience what there are, are different bandwidths/levels of perception that are all layered on "top" of one another that you can dip in and out of. They all have a median or a stabilizing point but they all bleed together in the same space.
What people call the "after life" is really a shift in perspective. Higher" bandwidths will always expose more sides/aspects/layers/depths/textures/senses than the previous. It's like going from watching a 2-dimensional image on a TV screen and stepping outside into the "real", 3D world. It doesn't stop there...the problem lies in the conditioning and manipulation to put a cap on where the minds of the masses can go. This creates a veil that makes it seem like you have to "die" to experience more after "life" when it's available to you right here and now.
