被遗忘的时光

The lyrics describe someone alone as a sound at the window and the touch of music bring back a happy time from the past. At first, the memories seem forgotten, but they gradually return. The speaker becomes quiet and absorbed in remembering, so the mood moves from gentle curiosity to wistful reflection.

The repeated questions, “Who is knocking at my window?” and “Who is touching the strings?” give the sounds a mysterious, almost personal quality. They may be ordinary noises, or they may stand for the way music and rain awaken memories. The image of memories rising into the heart and appearing in the mind suggests that the past comes back slowly, rather than all at once. The falling rain also creates a soft, lonely atmosphere.

The song does not explain exactly what happened in the remembered happy scene, or why the speaker is alone now. That absence leaves room for different readings: the past might be tenderly missed, or remembered with a quiet sadness because it cannot be recovered. The speaker does not directly say they want to return to that time; they simply revisit it in silence.
