A Conceptual Reversal Twist comes as part of a work that lulls the viewer into believing that they are watching one type of story before an abrupt reversal that usually comes at the very end reveals that everything one assumed about what was happening is not the case at all.
The two most famous Conceptual Reversal Twists are those that come at the end of Planet of the Apes (1968) and The Sixth Sense (1999), which offer jolting surprise twists about the protagonist’s conception of the world around them or who they are.
A famous Conceptual Reversal twist is the Deathdream Ending where the protagonist discovers that they have been dead all along or are in the process of dying. This, along with other twists such as that everything that transpired is All a Dream or a Virtual Reality illusion, has become a cliche from overuse.
The success of The Sixth Sense gave the ghost story the seeming need to have to pull last minute twists in every film made since to the point of frequent tedium. Such twists have also been popular in science-fiction works or Psycho-Thrillers that reveal characters are split personalities or imaginary.
The Conceptual Reversal Twist is very similar to the Conceptual Breakthrough Story where the protagonist comes to a new understanding of themselves or the world they live in, although not all Conceptual Breakthrough stories come with a Conceptual Reversal Twist. The crucial difference in the stories listed here it is the audience rather than the protagonist who makes a discovery about what they believe to be true.
