For a while these reveries provided an outlet for his imagination; they were a satisfactory hint of the unreality of reality, a promise that the rock of the world was founded securely on a fairy's wing.

Context
Continuing the description of young Gatz's nighttime fantasies, Nick explains how these dreams functioned psychologically—they allowed Gatz to believe that the solid, limiting world of poverty and class was not truly fixed, but could be reimagined and reconstructed.
Analysis
The oxymoron 'unreality of reality' articulates the novel's deepest philosophical concern: Gatsby's power derives from his refusal to accept the material world as final, treating reality as malleable and subject to the will. The metaphor of 'the rock of the world founded securely on a fairy's wing' inverts stability and fragility, suggesting that what appears most solid (social hierarchy, class position) is actually arbitrary and dreamlike—a conviction that simultaneously enables Gatsby's audacious self-invention and guarantees his eventual destruction.
How to Use in Essay
Excellent for essays on how the novel philosophically interrogates the boundary between dream and reality, or for arguing that Gatsby's tragedy stems from a worldview that treats material reality as infinitely revisable.
