Taylor Swift fans are getting AMNESIA at her concerts due to a rare phenomenon 

When you go see Taylor Swift live, you expect it to be an unforgettable night – but there are increasing reports of people suffering from amnesia after her shows.

Jenna Tocatilan, 25, from New York, said she’d dreamed of seeing the pop star for so long that it was hard to hold onto what was going on in her mind.

She told Time magazine that “post-concert amnesia is real,” adding, after watching Swift perform a “surprise” song, “If I didn’t have the five-minute video my friend kindly made to jam to it, I probably would have told everyone it didn’t happen.’

Nicole Booz, 32, who attended Swift’s May 14 show in Philadelphia, said looking back it felt like “an out-of-body experience, like it didn’t really happen to me.”

Experts say there’s good evidence to explain the phenomenon, which isn’t just happening to Swift superfans who call themselves Swifties.

Neuroscientist Dr Dean Burnett, honorary research fellow at Cardiff University, said: ‘When you’re at a concert by someone you love, surrounded by thousands of very excited other people, listening to music that you have an emotional connection to, then Is it that many emotions are happening to you at the same time.

“Not only is it tiring on the brain, it also means that all the things you experience have a high emotional quality, which means nothing “stands out,” and that’s important if you want to reminisce later on.”

Dr. Ewan McNay, an associate professor in the psychology department at the State University of New York at Albany, said people’s brains respond to extremely positive emotions the same way they respond to negative stress.

This overload can make it harder to form memories, but he has some advice for fans.

He said, “People could try jumping up and down and shouting less, to contain the excitement.”
