Taylor Swift's pop album 1989 may have released last October, but there is still so much to learn about it.

Swifties and non-Swifties alike seem to know all there is to know about singles "Shake It Off," "Blank Space," "Style," "Bad Blood" and even "Wildest Dreams," but there are so many other terrific tracks off the singer's fifth studio album.

As part of Swift's cover shoot for GQ, which her being the cover star has been rather controversial, she spoke with Ryan Adams, who recently released his own cover album of all of her 1989 tracks, about the album and more.

In the video below, the 25-year-old revealed to Adams that "All You Had To Do Was Stay" happened to be inspired due to a dream she had.

"This is my first question because I think it's an interesting question. Have you ever dreamt a song? Or a lyric of a song? A riff of a song?" Adams asked Swift, which made her eyes light up.

"Yes!" she declared, adding, "The song 'All You Had To Do Was Stay' there's this really high-pitched 'Stay'. I had a dream that my ex showed up at my door. Knocked on the door and I opened it up and I was about ready to launch into like the perfect thing to say and instead all that would come out of my mouth was that high-pitched chorus of people singing 'Stay'."

"And then you go to say something else and it's like 'Stay, stay, stay' and I woke up and I was like 'that was mortifying, but that's kind of a cool vocal part,'" Swift further shared.

Swift even deemed that part of the song is "really weird."
