In terms of lyrics, the song is "about nightmares and all that goes with them," according to Chris True article in Allmusic. Tim Grierson, editor of Blender magazine, believes that the lyrics superimpose the bedtime rituals of children with the imagery of nightmares and the effect of fear.
The main riff of the song has been defined as "sinister" by P.J Howorth in The Wah Wah Book. Chris True, reporter for All Music Guide, highlights the contrast between the brightness of the children's bedtime with the darkness of the song.
The song was nominated for a Grammy Award for "Best Rock Song" in the 1992 edition. Years later, Rolling Stone magazine ranked the song 399th of the 500 best songs in history, and VH1 ranked it 22nd of the 40 best heavy metal songs.
