The phrase is a bit ambiguous in this context. It could refer to a few different things, and I want to make sure I write the right essay for you. Did you mean:

A of the "target demographic" for a product or brand titled "Dreaming About You" ?

A exploring the concept of how modern advertising and demographics "dream" about or curate the lives of consumers?

as a musical artist (specifically the track "Dreaming About You" )?
