Déjà vu has been explained exceptionally well in Wikipedia:
The experience of feeling sure that one has already witnessed or experienced a current situation, even though the exact circumstances of the prior encounter are uncertain and were perhaps imagined. The experience of déjà vu is usually accompanied by a compelling sense of familiarity, and also a sense of “eeriness”, “strangeness”, “weirdness”, or what Sigmund Freud calls “the uncanny”. The “previous” experience is most frequently attributed to a dream, although in some cases there is a firm sense that the experience has genuinely happened in the past.
I have experienced this sensation a number of times in my life, and it is indeed the weirdest and most uncanny feeling. To understand that we live more than once is pivotal in understanding this, as the root cause of déjà vu comes from the subconscious/soul recollection of a very similar event that has happened in a previous life, or something that happened in the Atlantean time (the period of time between the Fall from Grace and our physical lives on Earth).
Although the circumstances around the event are unlikely to be the same, it is close enough (especially emotionally) for this experience or awareness to be triggered. If nothing else, it is something we can share and feel we have in common with others, that goes beyond our own ordinary everyday lives, but it may also signal a healing of some sort, I am not sure.
