"Nightmare" is a song by American singer Halsey. It was released as a single on May 17, 2019, and was sent to top 40 radio on May 21, 2019, through Capitol Records.[1] The song was written by Halsey along with its producers Benny Blanco, Cashmere Cat, and Happy Perez. The music video, directed by Hannah Lux Davis, accompanied its release the same day.[2] The song was added as a bonus track on the extended version of Halsey's fourth studio album If I Can't Have Love, I Want Power.
In May 2019, Halsey posted a link on her social media, directing users to the website "nightma.re" to sign up for email alerts and prompting them to share what their worst nightmare is. The site gave a series of options, and upon clicking one of the options, users would be shown an explanation as to the meaning of that specific nightmare.[10] Fans also believed that the time tickets for her recent intimate concerts went on sale, 5:17 PM, was a hint towards the date new music would be released,[11] although Halsey claimed no knowledge of this and only said new music would be coming "sooner than you think".[10] She then announced the single's release date on Twitter on May 9, 2019, posting a video of her revealing the title at one of her concerts, and captioning it "new single. NIGHTMARE. may 17th".[1] Several days later, Halsey announced she had hidden lyrics of the song in five US cities: Los Angeles, Dallas, Chicago, San Francisco, and New York City.[12]
On May 20, 2019, Halsey performed a free show for fans in Minneapolis, where she performed the single live for the first time, along with "Castle", "Gasoline", "Without Me" and "Don't Play". She uploaded a video of some of the performances on YouTube following the show.[13]
The song has received positive reviews. Billboard magazine said the song is musically "unorthodox" containing "stylistic curveballs" and "killer lines" that "exalt autonomy, sexual freedom and self-acceptance".[17] The line "I've been polite, but I won't be caught dead/ Letting a man tell me what I should do in my bed" was noted as a "barbed assault on patriarchal expectation" by Billboard and "a necessary gesture of rage and empowerment" by Rolling Stone.[18]Billboard named it the 17th best song of 2019.[19]
"Nightmare (Reprise)" is a song by Halsey included on the Walmart bonus track edition of her fourth studio albumIf I Can't Have Love, I Want Power (2021). The song is a re-produced version of "Nightmare" created to match the sound of the album. It was first teased by Walmart when a 25-second snippet of a censored version of the song was posted to their website as promotional material for their Walmart exclusive version of the album.[68] It was later added to the extended edition of the album along with "People Disappear Here" and the original "Nightmare".
