I am unaware of aliens telling people messages of things they needed to know, especially things they had no clue they would need to know.
Aren't these the best kind of revelations?
Asb, I am a God, and I'd like to tell you something. Now there might be something you need to know the answer to, and it might prove that I have some special powers if I can anticipate that, but instead I would like to reveal something to you that you have no clue you need to know.
I hereby give unto the number 19.4503. You don't think you need to know that, but I assure you that you do.
These experiences sound more like Grays than Gods. Grays are mischievious and tricky and don't necessarily have the betterment of manking in mind when they intervene.
My biggest question to anyone who experiences these kinds of things is, why are you so special? Why are gods visiting you and not the prophet, or why aren't they instead out fixing worse problems with their direct intervention? I'm sure there are plenty of rape and slaughter victims in the darkest parts of Africa who could use some information more badly than your typical confused american youth. So then you have to think, well maybe greater things will result and that's why it had to happen. But the few people I know who claim these kinds of drastic interaction with supernatural beings (good or bad) don't go on to do anything anyone could really call significant.
It's like, God is giving funky experiences for the sake of the person having a funky experience.
