Question

Explain why do we suffer from deja vu?

Answer 1

the reasons why we suffer from deja vu

• Things Have Become Out Of Sync In Your Brain :-This happens when a situation triggers a "strong response of the 'fast' pathway, and the 'slow' pathway then catches up fractions of a second later."                
• There's A Neurological Mismatch :- there can be a temporary mismatch that can mess with our memory. This explains why something that has never occurred can feel like it has.
• A Glitch Is Throwing Things For A Loop :- "Because déjà vu often occurs suddenly — with no warning — and is fleeting in duration, it’s incredibly hard to study in a clinical setting in a healthy population," Neuroscientist & Holistic Wellness Expert, Leigh Winters, tells Bustle.
• If You've Been Diagnosed With Epilepsy :- "It has been reported that some with epilepsy experience this phenomenon right before a seizure — specifically when seizures begin in the MTL, an integral brain region for long-term memories and events"
• You're Young :- "About 60-70 percent of people report having déjà vu, but it's likely that it occurs more commonly," says Dr. Giordano, "and déjà vu occurrences are generally more common in younger people."
• You've Lived A Past Life :- Although the chances are slim that you'll find a neurologist who agrees with this assessment, if you believe in past lives — a belief you're completely entitled to — this "reason" is worth noting.
• Your Brain Is Working :- Déjà vu is actually a good sign, and seems to reflect the brain's ability to process memories at different levels and at differing speeds," says Dr. Giordano.
