It turns out déjà has siblings:

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 more commonly explained as when a person momentarily doesn’t recognize a word, person, or place that he/she already knows.

The phenomenon is often grouped with déjà vu and presque vu (together, the three are frequently referred to as “The Vus”).
