Does this not imply that Ygerna was the one who showed you the vision, and was actually pretending to be Talana BEFORE she is actually dead? That text would seem to contradict anyone saying Ygerna gets in your head after the vision, rather than before.
It does rather. Shame, really, I preferred the idea of Talana also being conned by Ygerna, but I guess the likelihood of Talana being involved at all seems a bit slim with that in mind.
