"Dreamlover" is a song recorded by American singer-songwriter and record producer Mariah Carey, released on July 27, 1993 by Columbia Records, as the lead single from the singer's third studio album, Music Box (1993). Its lyrics were written by Carey, with music composed by Carey and Dave Hall, and was produced by Carey, Walter Afanasieff and Hall. The song incorporates a sample of the hook from "Blind Alley" by the Emotions—previously used in "Ain't No Half-Steppin'" (1988) by Big Daddy Kane—into its melody and instrumentation. "Dreamlover" marked a more pronounced attempt on Carey's part to incorporate hip hop into her music, as was seen in her decision to work with Hall, who had previously produced What's the 411? (1992) by Mary J. Blige. This was partly in light of the mixed reception to her previous studio effort Emotions (1991), which featured gospel and 1960s soul influences. Lyrically, the song pictures a protagonist calling for a perfect lover, her "dreamlover," to whisk her away into the night and not "disillusion" her like others in the past.
