Would it be possible for the sake of gaining knowledge of the afterlife process to communicate with the recently deceased and ask them specifics of exactly what they went through from start to finish from the time they were dying to there current circumstances? Also to communicate with many, as in hundreds of them to get an overview of information to draw parrellels ect. Kind of like Raymond Moody and his work with NDE subjects except ones who fully crossed over and either are integrating into their new surrounding and or have been there for some time and are willing to work with humans.
