To dream of country music represents feeling good noticing nothing ever having to change. Emotions being generated that feel good always noticing that life is simple or never stops being the way it always has. Loving nostalgia, reminiscing, or enjoying seeing life repeating itself.
Negatively, country music may reflect feelings of embarrassment being annoyed that someone else enjoys never changing behavior that you feel is for losers. Being bothered by someone else that feels good never growing up.
