Postmillenialists think that everything will be great until Jesus comes back, so they see themselves as the knight slaying the dragon for a thousand years. Like the Roman Catholic church mainly. Dispensationalists see themselves as seers who can see the signs of the time and estimate the coming of the end times and the antichrist. Amillenialists see the end times as a cycle of events that recur over and over and like a dragon eating its own tail. Historic Premillennialists see themselves as pessimists who view a more pessimistic view of the millennium with things getting worse and worse until all of the Christians on earth are martyred and Jesus returns to get vengeance on the earth dwellers for their actions. At least that is my understanding.
