Déjà vu is a feeling rather than a phenomenon that one can pinpoint in a brain scan. Talking in percentage, 90% of us experience déjà vu in our lives. Déjà vu happens mostly in teens and 20s and approximately never in the age of 8 or 9. In this article, we will help you in familiarizing yourself with déjà vu.
THEORIES BEHIND THE CAUSE OF DÉJÀ VU
Déjà vu doesn’t have any rock explanation but there are some theories among which few will be discussed below:-
Our brains keep on examining our senses to check if the experiences that we are having are familiar. Once the stimulus is established as familiar by our brain, the hippocampus (a different brain region) will recall the memory that has been associated with it. This re-fires the neural circuits holding the piece of our past and thus we live the experience once again in our minds.
If the above cycle runs out of sync, that is if something is familiar but we fail to recognize it, it is then labeled as déjà vu.
Smells, sounds, sights when mixed together form an event. So, the second theory of déjà vu implies that if any one of the stimuli runs out of sync, the information arrives later which then will be identified as a total another event. This makes us feel that it has happened before hand
Another theory suggests that when a person focuses on one portion of the environment, the rest of the world drifts into unconsciousness. After the phase of unconsciousness, when our brain returns to reality, it makes us feel as if it has happened before
Though there are dozens of explanations in the world about déjà vu, the ‘what’, ‘why’ and ‘when’ of déjà vu remains unknown to us. The solution of getting to the bottom of déjà vu is by experiencing it all over again.
