Déjà vu: The Curious Feeling of 'Already Seen'
What is Déjà vu?
Déjà vu is a perplexing phenomenon characterized by the sensation that an event, place, or person has been encountered before, despite the awareness that the experience is new. It is often described as a vivid sense of familiarity, coupled with a strong conviction that the current moment is a repeat of a past event.
Possible Causes of Déjà vu
The exact cause of déjà vu is still unknown, but several theories have been proposed. One theory suggests that it occurs due to a momentary delay in the brain's processing of information. This delay can lead to the brain briefly registering an event as something that has already happened.
Another theory attributes déjà vu to a temporary malfunction in the brain's memory system. This could cause the brain to retrieve a false memory or create a false sense of recognition.
Déjà vu can also be triggered by certain factors, such as fatigue, stress, or certain medications. It is more likely to occur in individuals with epilepsy or migraine headaches.
