While reading A Storm of Swords I reached the chapter where Jaime is being treated by Qyburn and I want to know more about Jaime's dream:
Jaime closed his eyes and let the wine and Qyburn do their work. “Tell me of the battle.” As keeper of Harrenhal’s ravens, Qyburn would have been the first to hear the news.
“Lord Stannis was caught between your father and the fire. It’s said the Imp set the river itself aflame.”
Jaime saw green flames reaching up into the sky higher than the tallest towers, as burning men screamed in the streets. I have dreamed this dream before. It was almost funny, but there was no one to share the joke.
I believe Jaime knew about the caches of Wildfire under King's Landing which the Mad King was wanting to light during the sacking of the city, so I'd be satisfied to believe that he's just saying "I thought about this during the sacking of the city", but before that I was wondering if there was any further evidence for or against the other possibilities:
- That Jaime really had a prophetic/green dream about it
- That Jaime was actually tormented by this since he killed the King
