Once, while in college, I had a dream about being with a beautiful naked young woman. Upon waking up, I felt compelled to pencil a portrait of the girl from my dreams. A few days later I meet a young coed that looked exactly like the girl from my dream. We went out, I mentioned the dream and she went back to my place to see the portrait. We got naked..
Sounds like a good line to use.
"I had a dream about someone just like you... and I drew her once I woke up. Come back to my place to see it?"
