Doctor explains the science behind why we all get the feeling of deja vu

The feeling of déjà vu can be a bizarre experience that forces you to second guess your own memory.

It evokes a sense that you’ve already experienced the present situation before, with the French phrase translating as ‘already seen’.

And while some theories suggest that déjà vu is the brain recalling a memory from a previous life or could even be a premonition of the future, a doctor has revealed some of the science behind it.

Dr Karan Raj has gained millions upon millions of views on his TikTok channel sharing advice, quirky facts and a glimpse at life as a medical professional.

Tackling the subject of déjà vu, he explained: “What is déjà vu? It’s basically a glitch in your brain.

“It’s when a new short term memory gets accidentally stored in the long term memory.

“So it feels like it’s happened before because our brain is telling us it’s an old memory. It’s just sloppy admin by your brain.”

The video has been viewed more than 825,000 times and racked up more than 2,700 comments as it left people disappointed they didn’t have the super power they thought they did.

One person replied to say: “Me thinking I could predict the future.”

A second wrote: “That’s why I feel like I can time travel” and a third said: “I’ve experienced this soooo many times.”

Another asked: “Is it just me that gets deja vu where you also know what’s coming next, then spend the rest of the day thinking you’re psychic?”

And many said they have experienced something even more bizarre linked to their sleep, as someone else added: “How about situations you actually dreamed about but happen in reality way later? Serious question.”
