Science explains why certain people experience ‘Déjà vu’



‘Déjà vu,’ the term of French origin mentions a psychological phenomenon, which occurs fleetingly at any time and anywhere, affecting approximately 70 percent of the world’s population.

Most of us have had at least once in our lifetime a ‘déjà vu’ experience. It is a mysterious feeling where time seems to pass by in slow-motion, where you perceive information in such a way as if you had already experienced the current situation sometime in the distant past. However, none of us can explain it, little understand it. Researchers have mentioned numerous ’causes’ ranging from paranormal disturbances and neurological disorders and even multiple universes coexisting with ours.

When you come to experience a ‘déjà vu’ moment you feel mysteriously overtaken by a mysterious force which unconsciously tells you ‘this already happened before.’

According to a study by the Department of Neuroscience and Experimental Therapeutics at the University of Texas A & M, this psychological phenomenon has occurred in about 70 percent of the general population.

“Because no clear, identifiable stimulus elicits a deja vu experience – it is a retrospective report from an individual – it is very difficult to study deja vu in a laboratory,” points out Michelle Hook, a professor at the Texas A&M Health Science Center College of Medicine.

“According to many studies, about two-thirds of people have experienced at least one episode of ‘déjà vu’ in their life,” added Dr. Michelle Hook.

Researchers describe the phenomenon as the result of a “technical problem”  in the brain when a certain group of neurons related to the recognition and familiarity generates confusion between the present and the past.

However, Dr. Hook mentioned that according to some studies, the ‘déjà vu’ phenomenon can be attributed to a processing problem in the brain’s neural pathways.

Scientists explain it in the following way. Sensory information travels through several pathways before reaching higher cortical areas of the brain. The information travelling through different ‘routes’ usually reaches the brain at the same moment. However, there are exceptions when information does not reach the brain at the same time causing the ‘déjà vu’ feeling.

“Some scientists suggest that when a difference in processing occurs along these pathways, the perception is disrupted and is experienced as two separate messages. The brain interprets the second version – coming through the slowed secondary pathway – as an independent experience. That is when the inappropriate feeling of deja vu occurs,” Hook explains.

Parallel Universe and  ‘déjà vu.’

According to Dr. Michio Kaku, an American futurist, theoretical physicist and popularizer of science, Parallel universes can explain the mysterious phenomenon and states that quantum physics provide the necessary details which suggest déjà vu might be caused by your ability to “flip between different universes.”

The idea that other universes (multiverse theory) exist has been supported by several scientists, among them Professor Steve Weinberg, a theoretical physicist and Nobel Prize winner. According to Professor Weinberg, it is possible that in the same room an infinite number of parallel realities coexist with us.

  1. I was watching a soap episode on TV when I had one I knew word for word and all the actions on the episode, at first I thought it was a reapeat but checked only to find it wasn’t it was really weird to say the least, I’ve also experienced time slips too only once mind but that was even stranger, what a strange world we live in and I reckon TPTB know all about this too and the afterlife but don’t reveal any of it to us this would give us far too much power if we knew we didn’t die

  2. The thing is u actually know what is going to happen they haven’t explained that

  3. I believe that we are all “is-bes”. Eternal spirits that are all knowing and every know and then we remember this life because we have already lived it. We got bored of knowing everything so we played a game of pretend and here we are!!

  4. …and some are now questioning whether or not the earth is really round… I’m not buying it. My deja vu is a sudden “knowing”. Example: I dream something last night. It actually appears in my life the next day at which time I re-live my dream, but actually.
