Taylor Swift fans have shared feelings of forgetfulness after seeing the pop-star performing on her highly anticipated Eras Tour. Speaking to Time, Jenna Tocatlian, 25, spoke about her experience seeing Swift at Gillette Stadium in Massachusetts. Speaking about one of Swift’s nightly surprise songs At the concert that Tocatlian attended the song was 'Better Man', but she said: ‘If I didn’t have the 5-minute video that my friend kindly took of me jamming to it, I probably would have told every that it didn’t happen.’ She added that as she waited to leave the stadium, during an hour-long wait, she found it difficult to grasp the reality of a night she had waited so long to experience. ‘It’s hard to put together what you actually witness,’ she told Time.

Taking to social media, many users have shared their inability to recall the events of the show, from small details to even significant parts of the concert. Some described having feelings of guilt after waiting so long to attend the show and leaving without explicit memories. Ewan McNay, an associate professor in the psychology department at the State University of New York in Albany, told Time that the experience may be a result of too much excitement. He explained that ‘this is not a concert-specific phenomenon - it can happen any time you’re in a highly emotional state.’ This is because as a result of feelings of excitement, the body’s stress levels increase, which in turn causes neurons associated with memory to start firing indiscriminately. McNay shared that this makes forming new memories ‘really hard.’ The biological explanation for this occurrence is due to the body seeing excitement as a state of stress. The body then starts pumping out the brain’s favourite molecule for memory: glucose. Because the body thinks it’s stressed, it doesn’t want to waste energy on memory formation. Your vagal nerves, which regulate internal organ functions, also become stimulated as a result of the perceived stress. All this causes the part of your brain responsible for emotional processing - known as your amygdala - to release a neurotransmitter called norepinephrine. This helps to categorise memories as having high emotional content, increasing the likelihood that they’ll be stored vividly in your mind. However, McNay goes on to explain that too much of this chemical release can actually invest the process, especially if caffeine or alcohol are included. Which leads to your brain struggling to create and store new memories. For those who want to try and have a better memory of an important event, whether it’s seeing Taylor Swift, or getting married, McNay shared some helpful techniques. He says to try and achieve a ‘semi-meditative state’ and relaxing. He also adds that physical responses such as screaming at a concert tells the body that you must be scared. If you stand still in a more relaxed state, your brain will know not to get too excited, and aid the formation of new memories. Have your say in our news democracy.

A theory has resurfaced online that pop star Taylor Swift was previously a 4chan user. For those who don't know, 4chan is an image board website known for its controversial and offensive content posted by users. For years, a theory has existed surrounding the Blank Space singer being a potential user on the site, and it has seemingly resurfaced as many talk about their clues for the theory. Here is some of the evidence users have gathered: 1) In November 2011, a user asked 4chan to name their cat, with one suggestion being Meredith. A day later, Taylor Swift debuted her her cat Meredith. 2) Faces very similar to Swift's have show up on 4chan. With users going so far as to compare backgrounds featured in the pictures on 4chan and other photos uploaded by Swift on social media. 3) A /b/tard (a forum on 4chan) claims they once spoke to a musician on Omegle who said her name was Taylor and that she was on 4chan. 4) A user on the forum asked 4chan why they would say if they knew Taylor Swift would be reading it. 5) "One of the 50 most famous people on the planet" asked the forum for questions. 6) A 4chan user posted "Nothing quite like a freezing cold, wintery beach", the same day Swift posted the same thing to Twitter. Of course, this isn't exactly the most compelling evidence, and it's more likely to be a regular person crafting the illusion of being Swift by taking photos form her social media and some sly Photoshop. 4chan's founder Christopher Poole (a.k.a moot) told /b/ forum to stop talking about it, saying the photos can all be found online and the screenshots are Photoshopped. He added that the photos are posted from an IP "that is definitely not her." Of course, when did a disproved theory stop anyone from believing it? "Taylor Swift pays moot to say she isn't on /b/ so she can remain anonymous", wrote one speculative user on Reddit. Sign up to our free Indy100 weekly newsletter Have your say in our news democracy.
