The concept of déjà vu can be pretty confusing, right?
You can say that again.
It stands to reason that over the years there have been many theories that try to explain the weird sensation that is déjà vu and why we get it, but an NHS doctor – who has over 2.5 million followers on TikTok – has potentially put an end to any further debate about what may cause it.
In a short informational video posted to the video sharing social media platform – that started out with a classic repetition joke, just in case you were unsure what the phenomenon actually was – Dr Karan Raj explained that: “It’s 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.”

He then concluded using the very technical term: “It’s just sloppy admin by your brain.”
Well it may not quite have been what we were expecting, but it certainly does make sense.

Before Dr Karan – who is well-known for his #schoolwithdrkaran series on TikTok and across various other social media platforms – stepped in to explain the phenomenon in simple terms, there have been many other theories to account for déjà vu.
It’s believed that déjà vu affects somewhere between two-thirds and four-fifths of all people, and is something which has fascinated scientists over the years.
However, they remain divided as to the cause.

Some experts believe it originates in the medial temporal lobes of the brain – which control long-term memory – however, they are unable to study the phenomenon deeply because déjà vu, by its nature, is fleeting and brief meaning it cannot be recorded or tracked, as it just happens and then goes away almost immediately.
Scientists have also looked at epilepsy to see whether it holds the key to déjà vu, as seizures also begin in the medial temporal lobe, and according to The Conversation, some researchers reckon they could somehow be linked.
It is possible to study the growth of seizures – which are essentially electrical overloads in the brain – and track them as they pass through the brain, and through this theory, déjà vu is also believed to be an electrical overload, stimulated in the rhinal cortices portion of the brain and then impacted upon the medial temporal lobe, and this would mean that a false signal is sent, implying that the brain has seen something before, even when it hasn’t.
Another theory holds that déjà vu occurs due to a failure of memory.
Although our brain’s “sloppy admin” still remains somewhat unexplained, Dr Karan has done a pretty good job of breaking down déjà vu for the masses, amassing over 338K views in the process.

A ‘legacy walk’ in memory of the Joe Thompson is taking place across Greater Manchester
Danny Jones
The ‘Walk With Me for JT’, a.k.a Joe Thompson ‘Legacy Walk’, is back next month, and Greater Mancunians are being encouraged to take part.
Returning this year following his tragic passing last April, the now annual charity walk has already raised thousands for charity and is set for another big turnout.
Joe Thompson, an ex-Rochdale AFC and Bury FC player, sadly died at just 36 following a long battle with lymphoma, having been diagnosed three different times in 12 years.
While the young husband and father of two’s story is a heartbreaking one, it has also become a source of inspiration for so many across the North West and, indeed, across the UK, with people once again gearing up to complete a fundraising walk in his name.
Set to honour him by making the journey from his adopted home of Rochdale all the way to Old Trafford, with Thompson having come through Man United’s youth academy, the 15-mile trek will start at his former club’s Crown Oil Arena and stop at Bury’s Gigg Lane as well as Salford City’s Peninsula Stadium.
First held in 2024 under the ‘Walk With Me for JT’ banner, the initial legacy walk saw the Bath-born footballer and countless others complete 21 miles in an effort to raise money for treatment.
Gone but never forgotten, the charity walk survives not only in the hearts and souls of his family, friends and other people’s lives he touched, but in the community spirit that his struggle and immense bravery in the face of illness helped spur on throughout the region and beyond.
Writing on social media, the Thompson family and the Foundation in his memory said, “Last year, he walked beside us. This year, we walk for him. This isn’t just a walk… It’s a promise. A promise to carry his strength, his belief, his light forward.
For every family facing illness. For everyone experiencing loss or hardship. For anyone who needs hope right now. Every step matters. Every mile has meaning. Whether you’ve walked before or this is your first time. You won’t walk alone.”
Join the annual Joe Thompson legacy walk on Saturday 2nd May 💙
Departing from the Crown Oil Arena, the 15-mile walk will finish at Manchester United's Old Trafford 🏟️
They signed off by adding: “Be part of something bigger. Be part of Joe’s legacy. Be part of the movement. Get a team together, invite your friends, colleagues and family and let’s raise funds to support The Joe Thompson Foundation.”
With the event beginning at 11am on Saturday, 2 May, there have already been numerous sign-ups, and you can expect even more to lace up their shoes and pay tribute to a local hero.
If you want to join in the effort and help do your bit, you can register for the 2026 Joe Thompson Legacy Walk right HERE.
Manchester rent is now ‘41% more expensive than five years ago, according to a recent study
Danny Jones
Yes, that’s right, as per some of the latest data on leased housing in central Manchester, it’s now approximately 41% more expensive to rent here than it was half a decade ago.
If you’ve lived in and around the city centre for long enough, chances are that you’ve already been feeling that difference, especially of late.
The ongoing cost-of-living crisis roughly began in 2021, following the economy and the world essentially opening back up after multiple lockdowns, so it’s little surprise that new research has shown affordability when it comes to renting has been on a slump ever since, too.
As well as the price of seemingly most things in everyday life going up post-pandemic, the average rental rate for even just a one-bedroom flat/apartment has jumped up significantly between 2020 and 2025.

That’s according to the numbers crunched by credit card experts, Zable, anyway.
Not only did their recent report cite the rent prices going up even before the cost of living crisis – essentially following the outset of the Covid-19 outbreak – but if their figures, the rate of inflation and the unwaveringly high demand for housing are anything to go by, this trajectory is likely to continue in 2026.
As of February this year, around one in three UK households is now a single-person occupancy, which already comes with its challenges (the Manchester City Council tax discount being a thin lifeline for countless), not to mention energy bills and the cost of groceries continuing on an upwards trend.
Put in the simplest and most reductive terms, it’s now almost £300 dearer for most people to live on their own than it was back in 2020, and besides Liverpool clocking in as second on the list of increasingly expensive cities to live (a 42.12% increase), Manchester came in third.

Another fear is that with lots of people finding it hard to manage living in other major cities like London, even those moving to Manchester are also having an impact on how available affordable housing is here.
That’s why schemes such as the new ‘social rent’ development over in Wythenshawe are so important to the current generations of renters, with the possibility of owning your own property in the future becoming increasingly difficult for so many.
It’s also worth noting that Manchester ranked fourth among the British locations where the cost of living is said to have increased the most over the past five years, with the average difference in annual spend growing by an estimated 22.84%.
