The leathery wings in the smoke are the dragons. The black flood is Victarion and the crumbling towers are the crumbling brick pyramids. The fire visions seem to be blury some time and Mel may just have seen high buildings collapsing.
It is just something that crossed my mind. If you have already been there, tell me and kick me out.
I like the notion that it's Casterly Rock attacked by the ironborn. If it happened just after Theon's execution it wold be one of the most ironic moments in the entire series.
