What is Déjà Vu?
Déjà vu originates from French where it signifies “already seen.” The peculiar experience involves recognizing a past occurrence even though one understands it exists as a current event for the first time. Étant donné que this experience occurs in 60-80% of individuals throughout their lives it remains one of the many unexplained phenomena.
The Science Behind Déjà Vu
The scientific consensus indicates déjà vu results from how our central nervous system deals with recalling memories. The explanation of déjà vu phenomena includes three major scientific theories.
- Our brain sometimes produces incorrect memory retrieval during present events resulting in a perceptual fulfillment of familiarity.
- The dual processing mechanism of our brain when consciousness and subconscious work at slightly different speeds may produce the illusion of immediately recalling a past moment.
- The connection of déjà vu to forgotten dreams causes some experts to suggest a link between dreams and real-life situations.
- Scientific evidence shows mini harmless seizures in the temporal lobe linked to déjà vu since the region manages memory operations.
Common Triggers of Déjà Vu
- Déjà vu happens by itself but the following factors tend to enhance its likelihood of happening
- A brain operating under tired or stressful conditions will experience higher rates of memory failures.
- Witnessing an environment that bears resemblance to another place you have previously visited.
