What brain phenomenon is somewhat of a mystery, but is believed by scientists to be a "neurological glitch that causes an experience to be registered in the memory before reaching consciousness"?

Meaning "already seen" in French, deja vu is a strange, but not too unusual, phenomenon in which you brain thinks you've experienced something already as you're experiencing. In some people, it feels as though you can even predict the very next thing that's going to happen. Scientists believe when that happens your neurons are recording the memory before you experience it in your consciousness.
