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 déjà entendu, déjà éprouvé, déjà fait, déjà pensé, déjà raconté, déjà vécu, or déjà voulu, depending on the experience or sense that is evoked.
