The way Taylor Swift’s fans move is like a full-on rainstorm.

Swarms of concertgoers who showed up to Nashville’s Nissan Stadium on Sunday for night three of the pop star’s Eras Tour were forced to shelter in place for close to four hours due to severe stormy weather.

An attendee tells Page Six exclusively that the restless crowd had to remain under covered areas of the otherwise outdoor stadium, including the various ramps and concessions.

“When we arrived, we were placed into forced shelter around 5:40 p.m. and had to remain there without movement until 9:30,” the attendee explains.

“Fans were body to body with the rain and wind hitting us from the sides,” they add. “The rain pooled around our feet as fans took their shoes off.”

The attendee says a few “lucky ones” wore ponchos but that even those who managed to keep somewhat dry were standing so closely together in such chaotic conditions that many people had panic attacks, got sick, threw up and passed out.

“Fans were getting antsy as they were being shoved into each other and security continuously kept trying to part their way through the masses,” our spy shares, noting that many concertgoers were separated from their groups amid the madness.

Our spy says the “only reprieve” from the high-stress situation “was fans breaking into song together.”

“Fans traded bracelets and cried until we were released out to the show without openers,” the attendee adds, excitedly pointing out that an equally soaked Swift, 33, eventually took the stage just after 10 p.m. and performed until nearly 2 a.m.

Swift’s set usually runs from approximately 8 p.m. to 11 p.m.

The lightning advisory was issued just an hour before the Grammy winner’s first opening act of the evening, Gracie Abrams, was set to take the stage.

Her second opener, Phoebe Bridgers, was also unable to perform.
