Dear Avira,
Who says they were told anything to tell others? The Gemara says there where over a million neviim…
I still find your fascination with ‘Ko Amar Hashem’ humorous.
In one instance there was a yid going around with messages from Hashem, making predictions, and performing signs and miracles. What exactly he was, has never been settled. And it seems like all the later mekubalim accepted his teachings until the Arizal redid everything.
If you have no idea what the sources say, you can learn them or talk to people who do. The fact is that you are denying an activity that you are admitting to having no knowledge of how it is performed. And I am asserting that you have never studied what Nevuah actually is. The Moreh Nevuchim is a good place to start.
But somehow you are convinced that you have all the knowledge you need. Which is some statement from Chabad that must be reversed. If Chabad would sleep in the sukkah, you wouldn’t.
