Billie Eilish’s “Bury a Friend” is based on her own dreams. The song is about a monster that lurks beneath the bed. In an interview with Ok! Magazine, she said, “I have these terrifying dreams. Sleep paralysis. Night terrors. It’s like the whole night is terrifying and then I wake up.” As she tells it, those dreams tie directly into the song: She said, “I probably wouldn’t have made that song the way it is if I hadn’t had sleep paralysis and nightmares.”

In the video, her doppelganger appears and threatens to swallow her whole.

“Bury a Friend,” peaked at #14 on the Billboard Hot 100 and has been certified Platinum. It’s from the album, When We Fall Asleep, Where Do We Go?, which has sold double Platinum.
