Symbolism in Game of Thrones?

What are some examples of symbolism and foreshadowing in Game of Thrones series?

I was thinking the name of each Stark child's wolf is indicative of that child's fate. Sansa's wolf, Lady- because Sansa is held at court and her only means of escape is her beauty and favor. Arya's wolf Nymeria, named for a warrior woman, and Arya becomes something of a warrior/killer. Summer being Bran's wolf and him becoming one with the sacred trees/ guardian of the Gods and seasons. Shaggydog being Rickon's wolf, would that suggest his escape into wildling areas? And Jon Snow's wolf being called Ghost- would that suggest he becomes a sentient white walker like Benjen Stark/Coldhands?

Any other symbols used?
