[2] "Dreamland" was written in early 2017 by Chris Lowe, Neil Tennant, and Olly Alexander at the Pet Shop Boys' London studio.

It's inspired by a fairground in Margate called Dreamland, but while I was writing it, Neil Tennant said to me, 'This makes sense right now with Trump closing the borders.'

Alexander added, "It was a dream come true to create something with two of my heroes, and spending time with Chris and Neil was an absolute joy.

"[8] "Dreamland" was released as a digital download on 11 September 2019, along with the news that a new Pet Shop Boys album was forthcoming in January 2020.

[7] On 25 October, an expanded package was issued on CD, digital, and 12-inch vinyl formats, with remixes of "Dreamland" and two new songs: "No Boundaries", from the play My Beautiful Laundrette, and "An Open Mind".

[12] Robin Bacior of Consequence of Sound described "Dreamland" as "a silky synth-pop track full of subtle hooks and cyclical build-ups.

[13] Stephen Daw of Billboard called the single "a glittering pop-disco production",[14] and Daniel Megarry of Gay Times said it was "a slice of synth-pop perfection".
