jamais vu (noun), Fr. — “Often described as the opposite of déjà vu, jamais vu involves a sense of eeriness and the observer’s impression of seeing the situation for the first time, despite rationally knowing that he or she has been in the situation before. Jamais vu is sometimes associated with certain types of aphasia, amnesia, and epilepsy…” and time travel—as Rasheedah Phillips uses the device in Recurrence Plot (2014).
“Jamais vu is most commonly experienced when a person momentarily does not recognise a word or, less commonly, a person or place, that he or she knows. This can be achieved by anyone by repeatedly writing or saying a specific word out loud. After a few seconds one will often, despite knowing that it is a real word, feel as if “there’s no way it is an actual word”. The phenomenon is often grouped with déjà vu and presque vu, or tip of the tongue.”
