There are at least two groups called Dream. Do add if another group/soloist called Dream is missing.

1) Dream was an American pop girl group, which was active in 1998–2003 and 2015–2016. Their biggest success came in 2000 with their track, "He Loves U Not", a transatlantic hit single. They are also known for the hit singles "This Is Me", "This Is Me (Remix)" and "Crazy" in 2003. Dream consisted of members Holly Blake Arnstein, Diana Ortiz, Melissa Schuman, Ashley Poole and Kasey Sheridan who replaced Melissa Schuman in 2002 until their reunion in 2015 where Melissa Schuman returned to the group. However on October 5, 2016 Ashley Poole announced via Snapchat and Facebook that Dream has once again disbanded and a new album will not be released.

2) Dream (ドリーム Dorīmu) was a Japanese pop girl group signed to the Avex Trax label since 2000 and Rhythm Zone since 2009. The group was formed as a result of a 1999 talent contest called "Avex Dream 2000". Originally a three-piece group consisting of Mai Matsumuro, Kana Tachibana and Yu Hasebe, the group has undergone many changes since its debut in 2000 on the Avex Trax label, and none of the original trio remained till disbandment. The original trio sold over 950,700 records, and in total the group has sold over 1,100,000 records over the span of 10 years.

On July 7, 2002, the main lyricist Mai Matsumuro left the group to pursue a solo career. After Matsumuro's departure, Avex held another audition to replace Matsumuro. Instead of one, six new members won the audition, resulting in an eight-member Dream with the debut single "MUSIC IS MY THING". On March 2004, Risa Ai left to pursue a solo career. They became a 7-member group as performed this way until 2007. During this time, the band's name changed from dream to DRM. In August 2008, Yu Hasebe left the group to pursue a solo career, leaving Kana Tachibana behind as the only original member of dream. Afterward, DRM became Dream again. In August 2010, Dream released their official major re-debut single, "My Way 〜ULala〜" on the Rhythm Zone label. On November 24, 2010, Dream released their first album as a six-member group, titled "Hands Up!" on the Rhythm Zone label.

On November 23, 2010, Tachibana announced that she would leave the group. This marked the departure of the last member of the original three-member group. She officially left the group on February 20, 2011. On March 30, 2012, Sayaka Yamamoto departed to pursue a solo career.

In late 2016, Erie Abe announced that she would be leaving the entertainment industry by the end of the year. On December 31, 2016, Erie Abe officially left the group and is hoping to study abroad.

On June 4th, 2017, it was announced that Dream had disbanded due to all members leaving to pursue on their own activities. Aya Takamoto would no longer be a vocalist or a performer, instead she would focus on behind the scenes as the E.G.family chief creative manager. Ami Nakashima will focus on her solo career, and Shizuka Nishida will be focusing on her co-ed group called DANCE EARTH PARTY. Read more on Last.fm.
