I Love Dream World (世界中のしあわせを歌おう) is the 15th single of Jpop band Dream. This would remain the group's symbol until their rebirth as DRM in 2007. The single reached #10 on the weekly Oricon charts and charted for six weeks. This is also dream's first single to chart within the top 10 on Oricon's weekly charts since 2000's "My will". First pressings came in a special package, and included one of nine trading cards. In its official title, the phrase "love dream" is represented by a combination heart/peace sign (resulting in frequent misreadings, usually "I love world" or "I world").
