I'm just reading A Clash of Kings now and I read the House of the Undying chapter last night. I noticed the following from the prophecy:
"A corpse stood at the prow of a ship, eyes bright in his dead face, grey lips smiling sadly. A blue flower grew from a chink in a wall of ice, and filled the air with sweetness."
Of course people talk an awful lot about the second sentence referring to Snow, etc. But people have wondered who the "corpse" is in the preceding sentence and suggested a number of candidates.

My question: could it refer to Jon Snow's death, resurrection, and future sailing to . . . somewhere (Hardhome, Meereen, King's Landing?)
