BlackMist

Usually I'd go ahead and use the comment section for our posts to mention something like this, but I really think I'm onto something here. After seeing last night's episode of Lost, I've got some thoughts on what's going on with that weird black mist, the island "security system," as Rousseau called it.

Recall in the episode titled 'The 23rd Psalm', where Eko confronted the black mist, face to ... mist. Looking closely at that scene, we could see flashing images within the mist, clearly images taken from Eko's memory. then, in last night's episode, we see many of the same images flashing in Eko's dream.
