@SmilerLoki, sorry, I wasn't trying to put you down by saying fan fiction. I was just meaning that when it's not offered in the text I can't begin to make up thing that could be happened 1000 years ago on Earwa. That's all. That's fan fiction to me and wasn't demeaning you in any way.
That being said, when you offered that maybe it (mundane dreams), has happened in the past, I brought up the Seswatha never shites phrase. Think on it a minute, Seswatha founded the Mandate, his actual being. And for 2000 years or however long, all the Mandate have been having the dreams. Now, over that period of time, "Seswatha never shites" becomes a catchphrase of the Mandate. Its pretty telling, to me, in all those years they never dreamed of the mundane, only atrocity of the 2nd Apocalypse. That's why I don't think it occurred and is the textual evidence that it hadn't. Because, it would be a big deal. And, that's how Akka knows to pay attention and documenting everything. Its mundane.
