Singer Taylor Swift thought up the chorus for her song All You Had To Do Was Stay in her dreams.
The Shake It Off hitmaker explains she had a dream one night where she was unable to talk and could only scream the word "stay" and she woke up and decided to add the shriek to a chorus in her song.
She says, "You'll hear in the chorus, you'll hear this high pitched 'stay'. It's like this stabbing, screech sound and that was the sound I heard in a dream... (where) I was trying to talk to somebody and all that would come out of my voice was that sound...
"I woke up and I was haunted by this sound; I was like, 'Why, that's the weirdest sound'. And so the next day I went into the studio and wrote a song and incorporated that into the chorus."
The track appears on her new album 1989.
