Do psychics and mediums all have the same beliefs about the afterlife and spiritual world? How did they learn this?

I think everyone has different beliefs and experiences. Some of the beliefs we have are learned (from parents and others), while others are from personal experience or from study (reading things online, books, etc.).

I think we all just end up forming our own theories and the like.
