The Afterlife is an area of human consciousness we all enter upon leaving the physical world at physical death. It is also the area we enter when unconscious, as in sleep. Physically alive human beings can learn to consciously enter and return at will to explore. Perhaps a better way to say this is that we can learn to focus our attention beyond the physical world. Physically alive humans don't really leave the physical world to explore, they just learn to focus their attention beyond it. There are specific areas of the nonphysical world that are inhabited by human beings who are no longer physically alive. These are the areas known as the Afterlife.
