Dreamt I found a perfect busking spot that doesn't exist

The acoustics were unreal — like the whole street was a guitar body. Foot traffic was steady, people actually stopped to listen, and there was a little alcove with shade. But the street was impossibly wide, like three lanes of cobblestone, and the buildings were too clean, no graffiti, no bird shit. Woke up in my flat with the radiator hissing and felt cheated.
