Taylor Swift
unveiled the full-length music video for "Out of the Woods" during ABC's Dick Clark's New Years Rockin' Eve With Ryan Seacrest on Thursday night. 

The 26-year-old singer battles the forces of nature -- crawling through the mud, running from wolves, jumping off a cliff -- in the modern day fairytale about a girl in a gorgeous gown who loses her prince but gains something even more valuable, herself.

"Out of the Woods" was co-written by Jack Antonoff and helmed by Swift's frequent collaborator, Joseph Kahn, who previously directed her "Blank Space," "Bad Blood" and "Wildest Dreams" videos. Kahn helped Swift score a Video of the Year award for "Bad Blood" at this year's MTV Video Music Awards, but received harsh criticism for "Wildest Dreams."

As for the text at the end of the video -- "She lost him but found herself and somehow that was everything" -- the song is rumored to be about Swift's relationship with One Direction's Harry Styles. While the 26-year-old has never confirmed the identity of her muse, she did open up about the situation that inspired the lyrics.

"This was a relationship where it was kind of living day to day, wondering where it was going, and if it was gonna go anywhere, if it was going to end the next day," she said in a video posted to her YouTube page. "It was a relationship where you kind of felt you were never standing on solid ground. And that kind of a feeling brings on excitement, but also extreme anxiety, and kind of a frantic feeling of wondering."

She also confirmed the real-life situation that inspired the line, "Remember when you hit the brakes too soon/Twenty stitches in a hospital room."

In an interview with Rolling Stone, Swift admitted that she had been sent to the hospital after a snowmobile accident with an ex (presumably Styles) and revealed how she kept the incident out of the headlines.

"You know what I've found works even better than an NDA?" she said. "Looking someone in the eye and saying, 'Please don't tell anyone about this."

Swift has made headlines throughout 2015 thanks in large part to her famous friends. ET has rounded up the 12 best surprise celebrity guests on Swift's 1989 World Tour in the video below. Re-live the madness!
