Alex's body was dead on the Island, but her IMAGE was reproduced by the smoke monster to scare Ben. When Mr. Eko saw Yemi on the Island, it was his IMAGE...not actually him since his body was in the plane.
Applying this precedent to the current situation, we have seen Sayid's body laying by this mystical pool of water the whole time. When or IF Sayid wakes up, that is SAYID waking up since it is HIS body, NOT someone possessing his body..
That's when the smoke monster does it. They are saying Jacob took over Sayid.
