Answer 1

The term "déjà vu" (French for "already seen", also called paramnesia) describes the experience of feeling that one has witnessed or experienced a new situation previously. The term was created by a French psychic researcher, Émile Boirac (1851–1917) in his book L'Avenir des sciences psychiques (The Future of Psychic Sciences), which expanded upon an essay he wrote while an undergraduate French concentrator at the University of Chicago. The experience of déjà vu is usually accompanied by a compelling sense of familiarity, and also a sense of "eerieness", "strangeness", or "weirdness". The "previous" experience is most frequently attributed to a dream, although in some cases there is a firm sense that the experience "genuinely happened" in the past.

The experience of déjà vu seems to be very common; in formal studies 70% or more of the population report having experienced it at least once. References to the experience of déjà vu are also found in literature of the past, indicating it is not a new phenomenon. While it has been extremely difficult to invoke the déjà vu experience in laboratory settings, therefore making it a subject of few empirical studies, recently researchers have found ways to recreate this sensation using hypnosis.[1]

Answer 2

first, space and time curve. Second there are other"dimensions"
where we exist due to other choices we have made (infinite possibilities). Third there are many paths to get to the same place.
Now, all that in mind what's commonly referred to as deja-vu is a point where the "you" in this dimension has crossed paths with the "you" from another. Not previous but simultaneous.
Or it could be a lapse in the control that your conscious mind has over the free roaming sub-conscious.
