"Dreamlover" received universal acclaim from critics, many of whom praised its production, the sampling of the
hook, and the vocals. In reference to the common criticism that Carey over-sings and over-uses her upper registers, Cummings wrote "truth is, she is never crass in the use of her amazing instrument. On 'Dreamlover', especially, she keeps a close, tasteful rein on the acrobatics."
J. D. Considine from
The Baltimore Sun called its melody "breezy", while
The Buffalo News's reviewer described it as "a sassy,
pop rocker with a dance beat".
Larry Flick from
Billboard magazine said it is "direct, unfussy, and profoundly pretty". He added, "The production is elegant but appealingly simplistic. Mariah's openhearted singing is up front, where it belongs, with a funky snare and kick-drum just a subtle half-step behind. The gliding, devotional pledge culminates in a lovely vocals-only tagline." Troy J. Augusto from
Cash Box named it Pick of the Week, stating that Carey "tones down the vocal here, her seductive, captivating voice flowing smoothly and beautifully on this sprite, sparsely produced love song".
David Browne from
Entertainment Weekly felt the singer's soft singing and lack of volume was hurtful to the song, saying she "lost herself." He thought the hook was catchy, but overly familiar. Blogger
Roger Friedman from
Fox News named "Dreamlover" and "
Vision of Love" Carey's best, calling them "the original hits." Dave Sholin from the
Gavin Report said that the song is "a pop delight." In his weekly UK chart commentary,
James Masterton noted, "This new track debuts strongly then, and being far more catchy and original than most Mariah Carey material may well breach the Top 10 at least." Chris Roberts from
Melody Maker praised Carey, who "sings with consummate power, grace and range over a
Janet-swing lagoon of a track, both languorous and sassy." Alan Jones from
Music Week gave it a score of four out of five and also named it Pick of the Week, deeming it as "an ultra-commercial, hook-laden and impeccably sung confection" that "starts with a supersonic screech and ends with an a capella tag." He added further, "In between, Carey exercises more restraint than usual in the vocal gymnastics department to great effect, proving that sometimes less is more." Jeff Silberman from
The Network Forty described it as "a delicious midtempo pop gem, bolstered by in-the-pocket instrumentation, Carey's pristine vocals and a velvet production sound".
People Magazine noted that "with its appealing girlish playfulness, it’s the kind of breezy pop she excels at." Tom Moon from
The Philadelphia Inquirer called the song "irresistibly bubbly".
The Plain Dealer noted that it "starts out with one of those upper-register vocal runs that can make dogs howl and shatter glassware in neighboring states." In a retrospective review, Pop Rescue stated that Carey's vocals "are confident, strong, and also perfectly partnered to this chilled out track", adding it as "wonderful" song. While reviewing
Butterfly (1997), Rich Juzwiak of
Slant Magazine praised the song's incorporation of the "Blind Alley" hook, saying it was done "as sweetly as possible."
Entertainment Weekly listed the song as one of "The 100 Greatest Moments in Rock Music: The 90s"; it was their top pick for 1993. "Dreamlover" received a
Grammy Award nomination for
Best Female Pop Vocal Performance. == Chart performance ==
