I've been listening to the recently archived recording sittings of the Yellow Cloud Circle of Physical Mediumship, where they were touring in Australia - fantastic direct voice phenomenon as usual, and dear friend John Sloan always a pleasure to hear. During one particular sitting, John confirms something Tim shared in The Risen, which is that there are skeptics in the afterlife, not just on earth! This can be heard about 5:40 minutes into the sitting. John speaks of how the now-transitioned skeptics still think they're right, because they still don't realize that the people they're now speaking to are Risen just like they are. About certain now-transitioned scientists, John says, "...they just can't get it through their thick skulls!"
This is what's noted in The Risen:
Not everyone is necessarily interested in contacting those left behind on the terrestrial plane after their transition to the Risen state. For one thing, it’s very difficult. And for another, the heightened reality of the Risen experience is so intense that many individuals quickly lose interest in earth and even forget they ever had a life there. Tim and others have told me that there are Risen who believe that their earth experience was all a dream—or a nightmare—from which they simply woke up. There are groups of Risen, including those who were once scientists on the earth, who maintain adamant skepticism that such a place as earth ever existed. When compared with their present reality, it simply doesn’t make sense to them and so they challenge others there to prove the existence of such a crazy-sounding place as “Earth.”
