In late August 1999, a live video of Dion performing the song was released to promote Au cà Âur du stade and the home video of the same name. Dion performed "Dans un autre monde" frequently in concerts between 1999 and 2020. In 2005, it was included on her greatest hits album On ne change pas.

In Wallonia (Belgium), the song entered the Ultratop Airplay chart after the release of Au cà Âur du stade. It reached number seven on 26 October 1999 and stayed inside the top 50 for seven weeks.
