Meaning of "Whiter Shade of Pale" by The Box Tops

The lyrics of "Whiter Shade of Pale" by The Box Tops seem to depict a surreal and almost dreamlike experience at a party. Despite feeling unwell, the protagonist continues to indulge in the festivities, perhaps as a form of escapism. The reference to the miller telling his tale could symbolize the passing of time and the inevitability of change, as seen in the woman's transformation to a "whiter shade of pale." The mention of "sixteen vestal virgins who were leaving for the coast" could represent a departure from innocence or purity, hinting at the loss of something precious. Overall, the song conveys a sense of disorientation, mystery, and the fleeting nature of moments.
