Just a Dream is a 2010 single by Nelly, known for its reflective lyrics about a relationship ending, while Overboard is a 2010 Justin Bieber song about falling deeply in love. Fans began pairing the two tracks because their themes and melodies complement each other, creating a bittersweet contrast between longing and devotion. Mashups like this spread through short-form video edits, where creators use familiar choruses to set a mood in seconds. The combination remains popular because both songs are instantly recognisable to listeners who grew up with early 2010s pop.
