After he remembers the fight his dream fades and he thinks of his sisters death. This implies those events are connected somehow. I think it's likely she was in the tower and I'm guessing died in child birth.
It's explicitly stated that after his sister dies while he is by her side, he remains for some time until Howland Reed, "The little Crannogman", leads him away by the hand. He and Howland were the only survivors of the fight with the Kingsguard located there. I don't think it can be an implied connection.
I'll say it again, Howland Reed for MVP!
-In another part he thinks of the secret he has kept for his sister and how much it has cost him. No more details than that, but it implies there is a dangerous unspoken secret.
A secret kept for 14 years, to boot.
Oh, and Remus, Eddard marries Cateleyn rigvht before going off to fight. He sticks it in her a couple of times for good measure (he is the Heir to winterfel now, with Brandon's death). That produced Robb as it turns out (catelyn was fertal, yes she was. And maybe Eddard was shooting cop killers to boot).
Eddard claims Jon was conceived while he was away on campaign. The idea being that war will do things to a man, he had been away from his wife for a very long time (a wife he barely new), and was more than a touch horny. The product of that lust was unfortunately Jon (excuse me, the alleged product of the alleged lust). Catelyn even explicitly thinks that she doesn't begrudge him the sexual encounter - merely the production of a bastard that he has rubbed in her face for 14 years by treating it like a child they had made (and explicitly by having Jon around all the time - she more or less thinks she'd have expected Ned to make sure Jon was well treated, merely that it should have been done out of sight).
