"I think it was a Dictaquill." So even if there was a way to track down the Dictaquill from the script, she didn't know how. Not that it brought them any closer to figuring out who it was. At least not through traditional means. There was always having a go with some divination and before that there was instinct, pure and simple.
"Although I don't think it would be that unreasonable for it to be someone you know. I mean, from what I'm learning there is some sort of pattern there and this sort of phenomena would be likely to have that sort of connections because it's dreams, nightmares, memories even random there would have to purpose." Or at least that was what she believed and her instinct told her was true.
