In spite of moderate sales and chart performances, the song remains one of the most known by the general public because of the subjects it deals with, notably war and a call for tolerance.

However, because of the fall of Farmer during a concert in Lyon on 15 June 1996, the song "Rêver" was chosen as the fifth single to make the fans wait, since the release of the live album would be deferred.

[1] "Rêver" was Farmer's first song to refer to the genocide of World War II, in the first line, through the book If This Is a Man, written by Primo Levi (the second single was "Souviens-toi du jour")[citation needed].

One line of the chorus, "J'irai cracher sur vos tombeaux", refers to a book by Boris Vian[3] under the pseudonym of Vernon Sullivan.

[2] A few time after the single release, Farmer performed the song in playback in one television show, Les Enfants de la guerre, on 27 November 1996, on TF1, in which she wore the same dress made by Paco Rabanne as that of 1996 concerts.

[10] The recording of the performance took place without the audience, which caused the anger of hundreds of fans who came from France and Belgium and who had waited several hours under the rain.

[18] Among the artists who perform "Rêver", there are Francis Cabrel, Pascal Obispo, Marc Lavoine, Patrick Bruel, Muriel Robin and Maurane.

Prohor Shalyapin, a former contestant of Russian television reality show Star Academy covered the song in Russian-language and his version is available on his own site.
