Déjà vu, where a person feels that the event happening in front of them seems to have happened in the past, is related to the process of information processing and memories in the brain.
According to Sanam Hafeez, a clinical psychologist and neuroscientist at Holistic Psychology Consulting, this is a phenomenon where a person feels a sense of familiarity when in a new, never-before-seen situation. Many people experience this condition many times, but the moment is too short to be aware of.
Déjà vu is a fleeting and common experience that affects people of all ages but is not considered a medical condition. About 60% to 70% of healthy people experience some form of déjà vu in their lifetime. WebMD points out that familiar sights and sounds can trigger the feeling.
“You can walk into a completely unfamiliar room or building and still feel like you know it,” Hafeez explains.
According to Health, déjà vu is more likely to occur in people between the ages of 15 and 25. People who are highly educated, travel a lot, and frequently recall dreams also have a higher rate of experiencing déjà vu.
According to Dr. Hafeez, the exact cause of déjà vu remains a mystery to scientists , but experts have put forward a number of hypotheses to explain this phenomenon.
Some believe it has to do with memory processing. The brain has delays or errors in retrieving memories. Another theory suggests that it may be the result of processing too much information through too many pathways at once.

Déjà vu is not generally considered a medical condition, but certain neurological disorders can cause déjà vu to occur more frequently.
These diseases include:
Epilepsy: Déjà vu has sometimes been reported as an aura symptom of epilepsy. This may be a sign that a seizure is about to occur.
Migraine: Some people who get migraines may experience a sense of déjà vu before the pain begins.
Temporal lobe epilepsy: This type of epilepsy occurs when there is an abnormality in the temporal lobe of the brain. People with this type of epilepsy may experience frequent and intense déjà vu.
Schizophrenia: Déjà vu is sometimes considered a symptom of schizophrenia. However, it is just one of many manifestations of this mental disorder.
Anxiety or stress: Frequent anxiety or stress can lead to distortions in perception, a feeling of unreality, similar to déjà vu.
