When I listen to the radio or watch TV, I often hear that something is "of your dreams". Yet it is almost never something that I dream about. The car of your dreams : I can't ever remember dreaming of a car; ditto for house or TV or vacation.
Most of my dreams are action dreams; usually I am a hero or a hero sidekick where we defeat the evil forces of evil. I remember dreaming about our youngest son after he died; often asking him wasn't he dead & he assuring me that he wasn't; a dream that often lasted shortly after I woke.
But I guess I am not the audience that the commercials are for.
