Deja-vu is often a feeling that we're experiencing something that we remember having experienced before. Have you ever experienced an instance of deja-vu that was wrong (like, not the way it was supposed to happen)?
(this felt right)
[Neo sees a black cat walk by them, and then a similar black cat walk by them just like the first one]
Neo: Whoa. Déjà vu.
[Everyone freezes right in their tracks]
Trinity: What did you just say?
Neo: Nothing. Just had a little déjà vu.
Trinity: What did you see?
Cypher: What happened?
Neo: A black cat went past us, and then another that looked just like it.
Trinity: How much like it? Was it the same cat?
Neo: It might have been. I'm not sure.
Morpheus: Switch! Apoc!
Neo: What is it?
Trinity: A déjà vu is usually a glitch in the Matrix. It happens when they change something.
