what dreams are made of

That which utterly fulfills one's ambitions or desires, especially in a way that seems surreal or beyond belief. A: "How do you feel standing here right now, having finally won the Ultra Bowl after so many people doubted you?" B: "I tell you, it's more than I could have imagined. This is what dreams are made of." I worked a dead-end office job for 20 years before I became a writer. Let me tell you, doing what you're passionate about for a living? That's what dreams are made of.
