I do believe that paranormal events occur, even seeing what seems to be persons ("ghosts"). The U.B. don't say much about that, except that spiritism is "scam" (my word).
 

Yet the U.B. says that we could see the midwayers if we had a different eyesight, i.e. ultraviolet. The U.B. also says that they choose to be seen; which could explain the "ghosts".

My point: is there anything in the Urantia Book that could help explain what we call paranormal activity? Perhaps there's some scientific explanation.
