People complain that there is never any consequences for your choices in TES, now that you have to choose something that will ultimately have a consequence you don't want it? No matter, you don't have to continue in the quest if you sleep. If you made a suggestion I could rewrite the quest trigger

You could simply walk away? Awaken from you dream.. Wouldn't that be more simpler?
I like you story though, wish Bethesda would create a story as grand as this. Well, instead of simply killing a dragon and nobody really knowing about it.
Becoming a Divine in Skyrim sounds a little too much though, maybe for the last ES game that happen or something.. But not now I guess.
That's just my opinion.
