A theory I had was that maybe when someone dies on the island, they go to Smokey's lair, since Smokey guards the underworld. Some of the dead Losties escape but they are in ghost form or some are able to whisper.
Maybe the whispering are of the dead inhabitants of the island and they are trying to warn the Losties to run. Ben said to Rosseau that when she hears the whispers, that she is to run away. Some are able to appear to the Losties but for a short period of time. Or maybe, the Smoke monster takes the appearance of the inhabitants i.e. John Locke.
I think that the dead people are either apparitions by the monster or the dead people are trapped on the island and can only communicate via whispers, short appearances, etc.
