Déjà vu is the feeling that one has lived through the present situation before. The phrase translates literally as "already seen"
Was hooking up with some friends and all of a sudden it just dawned on me that I have experienced the scenario with them before. With each sitting in positions I have seen before, making sentences I have heard from them before. I need you guys to share your experiences with dejavu.... Thank you

One explanation for déjà vu is that there is a split-second delay in transferring information from one side of the brain to the other. One side of the brain would then get the information twice – once directly, and once from the 'in charge' side. So the person would sense that the event had happened before. so, dejavu is a purely psychological thing. all claims of it being as a factor of reincarnation is unnecessary.
