"Lucid" (stylised in all caps) is a song by Japanese-British singer-songwriter Rina Sawayama, released on 25 November 2020 as the sixth overall and first single from the deluxe edition of her debut studio album Sawayama.

Sawayama first teased a collaboration with BloodPop on 2 October 2020, Tweeting out "BloodPop X Rina Sawayama Coming Soon" alongside a Polaroid picture with the words "Lucid Mix" written on it.

It was written by Sawayama and Lauren Aquilina in 2018 on the floor of the singer's apartment from a beat sent to them by BloodPop.

[4][5] The video was directed by Dave Ferner and Ksenia Kulakova, and was filmed at MARS Studios, owned by Bild Studios, in London, with all staff observing COVID-19 protocols during production.
