It was mentioned in the Theory About Hist thread that there's another theory in which the Hist originate from outside of the dream. Could anyone elaborate on this for me?I don't think it seems too plausible unless you mean Anu simply generated a copy of Hist he saw on the outside. How would the Dreamer literally pull physical beings from their previous world into their new one?

In the Anuad, it is said that Anu tried to put the 12 Worlds of Creation together and created Nirn. The Ehlnofey and the Hist were said to be the only survivors of the 12 Worlds. As the 12 Worlds were part of the Godhead's Dream, Anu "stole" them and used them in his own Dream. It's part of the "borrowing" bit of the Amaranth. Anu dreamed of creatures he saw in his Dream of origin.

Ah, so it's his own recreation in his mind. Not like he actually dragged them in. Thanks, that makes alot more sense with what I know about how the dream works

Yeah, here's how my friend on TESLore explained it:

Oh, that's actually a really nice explanation. So they're not just recreations, they're more exact copies knowledge and all. Essentially, they Perceive themselves as being svcked into the dream, however they are just copies of the ones in Anu's world. Okay, I like this theory.

Yep. They know they are inside another Dream, but they have knowledge of the current Dream and the old Dream as well.
