No one can write away someone else's doubts about the afterlife. Only someone who has experienced it themselves in the manner that you do and I have will have little or no doubt in their minds. Any story about a psychic reading can be met with skepticism and attacks from those who believe that every psychic is a fraud and skilled at asking questions in a way that makes the client believe. For example, see this great piece by Cedric Johnson https://medium.com/backyard-theology/i-met-an-atheist-in-heaven-1e976cf97ef4 and some comments from Dezmodium, Ben Roberts, and Jabberwockymp and probably more.
