I'm into my reread now. Read this chapter last night, and this dream of Jon's gave me chills. I guess having read all 5 books and knowing what all is to come, I could see the foreshadowing of Winterfell being taken.

Before long he found himself talking of Winterfell.

"Sometimes I dream about it" he said. "I'm walking down this long empty hall. My voice echoes all around, but no one answers, so I walk faster, opening doors, shouting names. I don't even know who I'm looking for. Most nights it's my father, but sometimes it's Robb instead, or my little sister Arya, or my uncle." The thought of Benjen Stark saddened him; his uncle was still missing. The Old Bear had sent out rangers in search of him. Ser Jaremy Rykker had led two sweeps, and Quorin Halfhand had gone forth from the Shadow Tower, but they'd found nothing aside from a few blazes in the trees that his uncle had left to mark his way. In the stony highlands to the northwest, the marks stopped abruptly and all trace of Ben Stark Vanished.

"Do you ever find anyone in your dream?" Sam asked.

Jon shook his head. "No one. The castle is always empty." He had never told anyone of the dream, and he did not understand why he was telling Sam now, yet somehow it felt good to talk of it. "Even the ravens are gone from the rookery, and the stables are full of bones. That always scares me. I start to run then, throwing open doors, climbing the tower three steps at a time, screaming for someone, for anyone. And then I find myself in front of the door to the crypts. It's black inside, and I can see the steps spiraling down. Somehow I know I have to go down there, but I don't want to. I'm afraid of what might be waiting for me. The old Kings of Winter are down there, sitting on their thrones with stone wolves at their feet and iron swords across their laps, but it's not them I'm afraid of. I scream that I'm not a Stark, atht this isn't my place, but it's no good, I have to go anyway, so I start down, feeling the walls as I descend, with no torch to light the way. It gets darker and darker, until I want to scream." He stopped, frowning, embarassed. "That's when I always wake." His skin cold and clammy, shivering in the darkness of his cell. Ghost would leap up beside him, his warmth as comforting as daybreak. He would go back to sleep with his face pressed into the direwolf's shaggy white fur.
