Deja Vu

Is it that deja vu is more than just the result of a random or predictive dream of what coincidentally may or may not be our future, or similar such scenario? Could it be more than just confirmation that you are on the right path at the right time? Could it be that perhaps you have actually been there before and the familiarity of the situation triggers the feeling? Perhaps we are living a life in circles, round and round again until we get it cracked? Or perhaps our more unusual dreams and feelings of vivid familiarity are the product of a link between ourselves here and ourselves across multiple dimensions in similar but varying circumstances, and that these feelings come from living in, or being linked to lives that have lived through such scenarios elsewhere before, or, at that very moment. Or perhaps the cause is not nearly as far out, perhaps the feelings come from a clairvoyant link we have with our fellow man right here, right now, we dream each other's dreams, and recognise what others have already seen.
