"Just a Dream" was well-received and garnered several positive reviews from critics. Matt C. of Engine 145, a country music blog, gave the song a "thumbs up" review, calling it one of the best performances of Underwood's in an album that otherwise contained "bombastic vocals". The single was also ranked number fourteen on the blog's countdown for the Top 40 best country music singles of 2008.
Billboard gave it a positive review as well: "The fourth single from Carrie Underwood's double-platinum
Carnival Ride finds the singer charting new territory. Previous singles have stuck to a similar lyrical theme, contrasting between Underwood's girl-next-door image with inspirational or family-centered songs… 'Just a Dream' delivers the heartbreaking, storytelling side of Nashville with the kind of song usually reserved for vets like one of her idols
Reba McEntire or
Martina McBride. Underwood convincingly sells the story of a young widow of a soldier killed in combat, using shades of her emotive vocal to convey anger and despair. While the subject matter is sensitive in this day and time—particularly for flag-waving country pundits—it is rooted in reality. Add Underwood's adoration by the format's listeners and there is bound to be an immediate and receptive response to this beautifully executed song." ==Music video==
