The song "I Dreamed of an Old Love Affair" by Ernest Tubb tells the story of a narrator who had a dream about an old love. In the dream, the narrator's worries and cares disappeared as the old love reappeared. However, upon awakening, the narrator realizes that it was just a dream. The lyrics suggest that the narrator has been feeling lonely and empty since the old love left. They loved the old love with all their heart and felt immense happiness when the old love expressed a desire to start anew. However, the reality is that the old love is gone, leaving the narrator feeling hopeless. The use of sunlight as a symbol conveys a sense of reality and clarity. When the sunlight reveals that the old love is no longer present, it confirms that the dream was just a fantasy. The narrator is left with a sense of longing and nostalgia while recognizing the emptiness in their current life. Overall, the song explores themes of lost love, longing, and the emptiness that comes with the absence of a significant relationship.
