Hello there iano,
I don't mean to sound rude, but what about cases of psychotic delusion? I had a friend who, during a psychotic episode, thought that hospital staff were robots trying to kill him. I think that in the cold light of day, we can all agree that the medical staff were not robots (well, maybe one or two of them), but at the time he sincerely believed it to be true. In fact he
assumed that it was true, thus passing your reality test. Simply assuming you are correct is no way to judge an objective reality, at least not if you wish others to take you seriously. Wouldn't you be more in honest in admitting that you have no certainties and take the veracity of any divine experience on faith alone?
