Déjà vu is French for "already seen." Déjà vu is an uncanny feeling or illusion of having already seen or experienced something that is being experienced for the first time. If we assume that the experience is actually of a remembered event, then déjà vu probably occurs because an original experience was neither fully attended to nor elaborately encoded in memory. If so, then it would seem most likely that the present situation triggers the recollection of a fragment from one's past. The experience may seem uncanny if the memory is so fragmented that no strong connections can be made between the fragment and other memories.
Thus, the feeling that one has been there before is often due to the fact that one has been there before. One has simply forgotten most of the original experience because one was not paying close attention the first time. The original experience may even have occurred only seconds or minutes earlier.
On the other hand, the déjà vu experience may be due to having seen pictures or heard vivid stories many years earlier. The experience may be part of the dim recollections of childhood.
However, it is possible that the déjà vu feeling is triggered by a neurochemical action in the brain that is not connected to any actual experience in the past. One feels strange and identifies the feeling with a memory, even though the experience is completely new.
