‘Dejavu’ is a familiar word, of French origin. The term literally means ‘already seen’. Essentially ‘dejavu’ is used to describe those experiences that we see or feel for the first time, but gives a feeling of having seen, known or happened before. Though Dejavu has been on for centuries only a few theories justify its occurrence.
What is dejavu?
Sometimes it may happen that you go to a particular place and gather a feeling that you have been to that place earlier. Though you may not remember exactly when, you sense it to have happened. Soon you end up deciding to have dreamt of it. Dejavu is this spectacular feeling. There is not even a single person who hasn’t experienced dejavu during his life. Majority of the people sense it during their youth, i.e. within the age group of 15-25.
Suggested theories of dejavu
Dejavu has been solemnly studied by psychologists for years. As a result a lot of observations have been reported. Since youngsters are the major subjects, many of the observations sound fantastic while being mysterious. Some researchers believe it to be the visions of ones ‘past life’ in the form of dreams. Some others are opinionated that dejavu is an unsolved mystery that involves the work of God.
The ‘previous life’ theory proposes that every individual has had a life previous to this one and after death; there is a phase of rebirth. When you get a new life, the old memories are automatically lost, but a link to it remains. Sometimes, a place that you visit or an event you witness could inactivate this link and provoke familiarity in a totally unfamiliar situation. This theory has a spiritual concern and is quite difficult to evaluate in terms of science.
Dejavu has been explicated in relation to ‘psychic connections’ as well. This theory flags that people share brain waves (thoughts) without deliberate manifestation of it. It points out that we could actually share our thoughts and feelings involuntarily with others. Thus when you receive others’ thoughts and patterns of vision, you start to feel them to be your own. Despite the interesting make-over, this theory is vague since it doesn’t prove how, when and to whom your ‘brain waves’ could get associated.
Science has also tried to explain dejavu majestically. In the scientific scenario, things are quite different.
Human brain is a self-established ‘genius’. When you feel or sense something, or come across a place or an incident, our super-brain tries to link this new experience with those that are already stored in it.
You might have lived a parallel situation before and your brain attempts to register the similarity. Another scientific view is the ‘biofeedback response’. As per this view, an experience or an image gets recorded in our brain like a photograph, before it is really processed by our sense organs. Then as routine, when this experience is dedicated to memory, our brain signals that it has already been stored and we get the dejavu feeling.
Whatever be the theory, dejavu is simply wonderful and worth a research.
