Jon's Dragon Dream - A Song of Ice and Fire - Game of Thrones

Jon's recurring crypts dream that he can never quite finish? I think there's going to be a dragon at the end of it, and I have a theory about how and why, as well as a new theory about where dragon dreams come from in the first place. The Pact of Ice & Fire and the "Winterfell dragon" are also discussed, as well as how Jon will e a dragon waking from stone when he's resurrected.
