Dream was an American girl group formed in 1998, primarily consisting of Holly Blake-Arnstein, Diana Ortiz, Ashley Poole, and Melissa Schuman.

The group was signed to rapper Puff Daddy's Bad Boy Records label and released their debut studio album It Was All a Dream in 2001, which peaked at number six on the Billboard 200.

Talent scout Debbie Fontaine selected Holly Blake-Arnstein (13), Melissa Schuman (14), Ashley Poole (13), and Alex Chester (13), four teens from California, to comprise a girl group called First Warning, which was later changed to Dream.

Following this, the group stopped working with Fontaine, who later sued Combs and Blake-Arnstein, Schuman, and Poole, but lost her court case.

An alternate song with the same name but different lyrics and production, titled "This Is Me (Remix)" was also released featuring rapper Kain and Sean Combs, and was later included on the compilation Totally Hits 2001.

[7] A lengthy search conducted by Sean Combs and the three remaining members led to Kasey Sheridan (15) joining the group in Fall 2002.

[5][9] Blake-Arnstein later noted that the sexier, more mature image pushed upon the group by Combs and their management was not a welcome change, and that she and the other members were no longer enjoying the experience.

Ashley Poole and Melissa Schuman pursued solo singing careers, and Holly Blake-Arnstein joined the California-based band Whirl Magnet.

This new iteration of Dream was given a soft launch via the official YouTube channel but would fail to make a proper debut following the departure of several members.

On August 25, 2016, former member Kasey Sheridan joined Dream on stage to perform "Crazy" at the Microsoft Theater in Los Angeles, California.
