Déjà vu, in simple words, is the feeling of having already experienced the present situation. A famous movie named ‘Deja Vu‘ also explains this phenomenon. It is an aspect of familiarity or ‘already lived through’ something. A study based on the mental phenomenon in 2004 claimed that about two-third of the population had Déjà vu experiences.
When Do Deja Vu’s Occur?
People who tend to have Déjà vu reported it once a year on an average. Also, medically and scientifically, it’s proved that Déjà vu mainly occurs in the state of extreme stress or conditions of fatigue. But, Déjà vu can be experienced by a healthy person as well, with no sign of any mental or physical illness. Also, Déjà vu is equally likely to occur in both men and women. In medical terms, Déjà vu is caused by the electrical stimulation of the cortex.
Has It Ever Happened To You?
People who claim to have experience Déjà vu said that their experience resembled a dream. People who are more likely to travel, experience Déjà vu more often as compared to individuals who do not roam around much. Also, as per reports, Déjà vu frequency tends to reduce with age.
Déjà vu has been associated with various models to explain it precisely. For instance, split-perception is the phenomenon in which a person’s attention to an activity is divided into two different perceptions by distraction, which may be as quick as an eye blink.
The first perception is likely to occur at below-threshold when a person’s attention is degraded. For example, if you were about to ignite your car, and you’re momentarily distracted by an insect in the car, by the time you return your focus in starting the car, your initial perception of putting the key into ignition may be counted as having occurred further in the past.
