Lyric discussion by jefusan 

Robert Smith has often said that many of his songs (including most songs on the album The Head on the Door) were inspired by nightmares.

Meanwhile, devotees of the Cure continue to debate the source of the song's subject matter, which feels like a hallucinogenic take on Mary Howitt's early 19th century poem, "The Spider And The Fly" (an inspiration Smith makes explicit when he whispers something reminiscent of the poem's opening line near the end of the song).

While Smith most often attributes "Lullaby" to childhood nightmares, fans have speculated that it's actually a metaphor for everything from depression to addiction and abuse. The latter interpretation was further fueled by a portion of an MTV interview where Smith talks about the song. "One particular night, my uncle burst through the window, and he did unspeakable things," said Smith, before adding with a laugh, "He didn't really."

Pope [the director of the music video] is quick to point out that his friend and collaborator's knack for imaginative storytelling often spills over into real life. "He's one of the hugest liars, but in a lovely cuddly sort of way," he says. "He frames his story however he wants to. So maybe that's one of his, shall we say, slightly made-up stories."
