the mental impression that a new experience (e.g., a scene, sight, sound, or action) has happened before; a common phenomenon in normal people that may occur more frequently or continuously in those with certain emotional or organic disorders. Also variously referred to as déjàentendu, déjàéprouvé, déjàfait, déjàpensé, déjàraconté, déjàvécu, or déjàvoulu, depending on the experience or sense that is evoked.
