Deja Vu is the phenomenon of feeling like you have lived that moment before. Deja Vu is derived from the French meaning "Already Seen".
Scientific evidence according to O'Connor "déjà vu occurs when brain areas, such as the temporal lobe, send signals to the frontal decision-making regions, indicating that an experience is repeating itself."
It is thought that as much as 97% of the population have experienced déjà vu at least once in their lifetime and 67% experience it regularly.
Deja vu can happen anytime and studies show that it can last for about 10 to 30 seconds.
This misfiring according to psychology, can be triggered by stress, lack of sleep, and some medications though for some experts, Deja vu has no serious impact it is a fleeting moment, other than feelings of confusion momentarily.
Another theory explains that Deja vu occurs due to the way the brain tries to process and store memories. This happens when the brain accidentally retrieves a memory that is similar to that situation even though not directly related to the situation.
There is also a unique characteristic of people who experience Deja vu according to research: Frequent travelers, people with high income, those with a remembrance of their dreams, and ages of 15 to 25.
The mystery of Deja vu has been made a popular subject in movies, books, and television. It's often used as a plot to explain a character's connection to alternate realities or past lives.
This mystery has remains one of the least understood phenomenon in human experience. While science continues to explore the possible explanations, Deja vu reminds us of the complex interplay between memory and perception.
