Why should that mean it isn't real?

As Snape lingers between life and death after Nagini's attack, his mind conjures a happy life with his once most hated student. When he awakens, he has to try and ignore his feelings or convince Harry that what he dreamed could be real. SS/HP. Explicit scenes and strong language. AU after final chapter. Slight Ginny bashing. Harry and Snape return to Hogwarts after the war.
