"Hallucinate" is a song by English and Albanian singer Dua Lipa from her second studio album Future Nostalgia (2020).

Lipa and Lewis originally connected through Frances and they had known each other for a while as they ran in the same London circles, but they never wrote together; he did a remix of her 2017 song "New Rules".

[9][10] The song features soulful flashes and a funky melody,[11][12] and incorporates elements of 1990s and 2000s music,[13][14] as well as dance-pop,[15] electro swing,[16] psychedelic,[15] and synth-pop genres.

[17] The production consists of a looped bass, pianissimo synthesizers,[18] hi-hats,[19] a synth bassline,[20] mercilessly scythed violins, cowbells,[21] EDM rhythms,[22] a post-disco house groove,[23] and retro drum beats, categorized as disco-house.

[27][28] It sees Lipa engaged in an all-consuming, addictive love and celebrating carnality and physicality as the gateway to higher ground.

"Hallucinate" was released through Warner Records on 27 March 2020 as the seventh track on Lipa's second studio album, Future Nostalgia.

[41] The singer wore a skin-tight jumpsuit with a crystal-embellished design and performed in a sci-fi themed set with a moon in the background.

[2] Neil Z. Yeung of AllMusic called "Hallucinate" a "rapturous out-of-body rave", while Entertainment Weekly's Maura Johnston labelled it "stardust-dipped".

[53] Of the same newspaper, Luke Holland called the chorus, "bigger than a God's tea cosy" as well as writing it "feels constructed by boffins in a hermetically sealed lab to be the most effective chrome-plated slammer it can possibly be".

[19] For PopMatters, Nick Malone stated it "flourishes" in the chorus as well as praising its hook, but criticized its baseline, writing it betrays what an obvious hit is.

[55] In The Daily Telegraph, Neil McCormick said that even though "Hallucinate" is a "minor track", it keeps up "the melody and movement with a spirit of sensual fun that would make Kylie Minogue weak with envy".

[56] For The Line of Best Fit, Chris Taylor viewed the song as a "blissful early '00s club floor-filler, the kind that gets limbs and sweat flying everywhere with abandon".

[14] In a positive review from Idolator, Mike Nied called it a "glory" and a "balls-to-the-wall delight bound to send your heart rate skyrocketing".

[17] Courteney Larocca of Insider wrote that it transports one to a "'80s jazzercise class or an underground rave", while Callie Ahlgrim of the same website praised how it hooks the listener in and labelled it "pop perfection".

[57] Uproxx's Caitlin White categorized the song's aesthetic as "neon-tinted" while Alex Abad-Santos of Vox called it a "starship laser-beam spectacle".

[58][59] Crack Magazine writer Michael Cragg thought it is equally as incredible as "Don't Start Now" and categorized its sound as a Daft Punk remix of a single from Madonna's Confessions on a Dance Floor (2005) era.

[61] In a mixed review from Under the Radar, Conrad Duncan stated "Hallucinate" does a "faithful impression of 2000s disco-house", but criticized it, writing "it might as well have been written as radio fodder for 2004".

[62] In Slant Magazine, Sal Cinquemani called it the most "bald-faced gesture" on Future Nostalgia, and wrote it would be a highlight on a "lesser album" but stating it feels "generic" being "sandwiched" between "Pretty Please" and "Love Again".

[70] Upon the release of Future Nostalgia, "Hallucinate" found success throughout Europe as an album track, charting at number 92 in Greece,[71] 28 in Hungary,[72] 99 in Italy,[73] 35 in Lithuania,[74] 89 in Portugal,[75] 67 in Slovakia,[76] and 73 in Spain.

[94] "Hallucinate" received gold and platinum certifications from Pro-Música Brasil and the Polish Society of the Phonographic Industry (ZPAV), respectively, for track-equivalent sales of 20,000 units in Brazil and Poland.

[95][96] After choosing "Hallucinate" as Future Nostalgia's fourth single, Lipa approached production company The Mill, an animation studio Titmouse, Inc. and director Lisha Tan with a 2D animated music video idea for the song, inspired by the 1970s disco heyday, with "the wacky characters, different rooms, diverse color palettes and a sense of never knowing which direction the psychedelic journey will take you on."

Tan then took the treatment began looking at iconic photos from the disco aesthetic of the 1970s and Studio 54, compiling references and inspirations from the debauched behavior and crazy costumes everyone was wearing.

There is the tingle of anticipation in the beginning, then multiple ups and downs, before you burst out at the end, triumphant!The video opens with an animated Lipa inhaling stars in the sky.

It then cuts to her performing in a black and white club, for a crowd of early 20th-century style cartoon characters with big eyes and bulbous shapes.

[102] She is then seen dancing with wide-eyed cartoon unicorns, vegetables, rainbows, ice cream cones and bunnies as well as on a disco floor in several colourful settings.

[111] Entertainment Weekly's Nick Romano compared the characters to cartoons from the 1930s and 1940s while also writing Lipa "transforms into the spiritual descendant of Betty Boop".

[104] Wongo Okon of Uproxx wrote it is "styled after early cartoons from a century ago" and called the storyline "colorful" and "psychedelic".

Due to their lack of time to make it, many of their designed typographic lockups were removed so they could swiftly move onto their next aspect of work, such as motion tests and quick experiments.

[128] He started creating the remix by adding some club-style concepts to Lipa's vocals,[129] with the final version including gurgling bassline, slinky synths, and West End disco beats.

[130][131] A skeletal ambient track,[132][129] he reduces Lipa vocals down to a whisper and incorporates elements of 1990s house and contemporary dance-pop.
