Everyone has been in this situation: You stop for a moment to realize and think: “I have been here before.” The situation is familiar and in fact maybe too familiar to think it is mere coincidence and therefore there has to be an explanation for they happen right? This is the topic of this post. Although, like other phenomena such as dreams, the reasons for a déjà vu are a topic for debate and only theories exist. In 2008, the movie titled Deja Vu (2006) starring Denzel Washington used deja vu as its title. Although the movie did not explore the phenomena throughout the film, it did conclude in the creation of one. This was later portrayed as Denzel found himself in different dimensions of time and space. A YouTube user with name [themidnitemare] created a series of videos where he asked in the streets of Hong Kong: “What is a déjà vu?” The majority of the respondents answered that a deja vu is a lapse of memory which occurs when you dream of a situation and then you find reliving the situation later in real life. Although this explanation sounds attractive and perhaps even plausible, it would still bring forth the idea of how is that dreams can bring fragments of the future so that we they be relived later.

 

The X-files and the movie Groundhog Day have addressed the phenomena.

There exists a few theorist in the field of neuroscience who have pondered on this problem and created a few possible reasons why a déjà vu happens. One of the general understandings over the phenomena is the insolvent of the temporal lobe. In a study published on the study of electroencephalography (EEG) signals from the rhinal cortices, hippocampus and amygdala in epileptic patience for whom déjà vu could be induced through electrical stimulation. Other studies and theories rely on studying the mismatch that exist in the brain during a constant attempt to create whole perception of our world with very limited input and the interplay between malfunctioning long and short-term circuits in the brain. Researchers then conclude that a déjà vu happens when there is “shortcut” in the way the brain handles this kind of processes and then you may experience that weird moment we otherwise know as déjà vu. What all researchers and theories do agree on is that we do not fully know what causes a “shortcut” in the brain or what induces a déjà vu to happen. This will leave science fiction imaginations like myself to wonder whether the theory of living through different realities at once, or many parallel universes at once is exactly what could be the cause of a déjà vu, which begs the question: Which reality are we living right now?   Sources:
