I feel like Sansa sleeps in her parents room because she was raped in her room (other than Jon telling her to) What do you think??
Yes, kind of. I believe, that her father’s and mother’s room, makes her feel somewhat safe, comfortable. It gives her warmth, to be in the room that her parents shared. If you think of it, Sansa, Arya, Bran and Rickon were all conceived in that room. Considering what that monster did to her, in her own home, I am not surprised at all, that she takes comfort in sleeping in their room. They had a happy marriage, they respected each other, shared their troubles and happiness, and they loved each other, really, truly, loved each other.
Their room represents, and symbolizes happiness, the happiness and serenity that was once in Winterfell, because Cat and Ned, were at the center of that serenity and happiness, they were the heart of Winterfell.
Poor thing has been through so much, and Arya just can’t give her a break. I just wish they’d sit down and talk it out, tell each other what they’ve been through. Not communicating is making things take a very bad turn. Let’s hope Bran will put his powers to good use, and put some sense back into the both of them, he has to make them see that neither of them is each other’s enemy in 7.07, that, Littlefinger is the enemy and that they have to work together.
