We know that the Whispers are ghosts who "can't move on".
Smokey said some things (later turned out to be lying, but still) about how "In order to leave, we need to all leave together."
Flafterlife Desmond said he wanted to leave, but he had to get all (or most, at least) of the others together before that could happen.
So I'm wondering.....was the Flafterlife, or "waiting room", essentially causing the whispers this whole time? Were the Losties able to experience it because some part of their being was tethered to the island even after they left?
