[1.2.398] Minar's Past

To your understanding based on what people have said that has no real grounding in the actual in-game text.
So, yes, it would be logical that the world would disappear if she wakes up... if it was indeed a fact that the Maple World is the product of her dream.

Of course, the fact that the Goddess now appears, sleeping, in the game is a rather large blow to that theory, at least in my mind.
Tell me, when's the last time you had a dream in which you were asleep?

stop being stubborn Viaje

I did all of my ToT quests before BB and yes, we are her dream. Whatever is going on is just a dream.
