Postcognition, also called Retrocognition, Past Sight or Retrospect is the psychic ability to visually perceive information about past events after they happen, without any guessing based on deductive reasoning and current knowledge. This ability occurs as a brief flash of the scene, or it may last longer. Sometimes, however, it can even be activated at will within whichever interval the user desires (the last six hours, yesterday) at which time it becomes Selective Postcognition, Selective Retrocognition or Selective Retrospect.
An incredibly rare manifestation of postcognition.
