Introduction

Research suggests that most of us have had a déjà vu experience at some point in our lives. As illustrated in the above stories, you are suddenly and

inexplicably overcome with a feeling that you have done this exact same thing once before-been in this place, engaged in this activity, said that phrase. However, it is impossible because to the best of your recollection, you have never been in this place before, been with these particular people, or engaged in this particular activity at any time in your past. Reduced to the simplest form, the déjà vu experience represents the clash between two simultaneous and opposing mental evaluations: an objective assessment of unfamiliarity juxtaposed with a subjective evaluation of familiarity.
