Déjà vu, this mysterious and fleeting sensation of having already experienced a specific moment, even when it seems impossible, has intrigued humanity for centuries.
This universal phenomenon does not choose age, culture or location; almost everyone has experienced this strange familiarity at some point in their lives. But what really is déjà vu? A glitch in the Matrix, a glimpse into a past life, or something more deeply rooted in our psyche and brain functioning?

Let's then explore the theories behind déjà vu, how it occurs in our daily lives and the physical and psychological explanations proposed by modern science.
What is Déjà Vu?
O termo “déjà vu” vem do francês e significa “já visto”. Ele descreve a sensação de que uma pessoa já vivenciou o presente momento, apesar de saber que isso é improvável. Essa experiência é comumente acompanhada por uma sensação de estranheza e uma convicção inexplicável de familiaridade.

Theories About Déjà Vu
There are several theories that try to explain the phenomenon of déjà vu. One of them suggests that déjà vu occurs when there is an overlap between current perception and an inaccurate memory, causing the brain to interpret the present moment as something already experienced.
Another theory proposes that déjà vu is a type of anomaly in the process by which the brain compares current experiences with past memories, resulting in a false sense of familiarity.
Déjà Vu in Our Daily Life
Déjà vu can occur in a variety of everyday situations, from conversations and meetings to visiting new places. Although these experiences are brief, they can leave a lasting impression, raising questions about the nature of memory and perception.
Physical and Psychological Explanations
From a psychological point of view, déjà vu has been associated with cognitive processes involving memory and attention. Some scientists believe the phenomenon may be the result of a brief desynchronization between the brain's short- and long-term memory systems.
Physically, brain imaging studies suggest that déjà vu may be related to activity in specific areas of the brain, such as the hippocampus, known for its role in forming new memories.
Conclusion
Either way, déjà vu serves as a reminder of the complexity and wonder of the human brain, an organ capable of transporting us, even for a moment, to a place outside known time and space.
Although déjà vu remains a mystery in many ways, advances in neuroscience and cognitive psychology are slowly unlocking the secrets behind this fascinating phenomenon.
