Hurley has some sort of abbilitie to see dead people from the island. Ever sence they left, he was seeing dead people. He saw Charlie twice, one in a police interorgation room. He saw Charlie in water, then swimming up to the glass. Two, he saw him in the mental institute. He says Checkmate Mr.Eko in the institute. He even said to Sayid that he sees dead people all the time. In season 5, Anna Lucia was a cop who made him pull over. She even said Libby says Hi. Maybe the ones whodied on the island are trying to get Hurley to resurect them. This would prepare for the "war "to come like Widmore said. But that doesent explain Christian, but he may be just a apperition, because he coudnt help Locke up. Any thoughts?
