In Salman Rushdie's book "The Satanic Verses," the quote reflects a profound sense of disillusionment. It highlights the intense emotional turmoil experienced by an individual who realizes that what they believed to be true or meaningful is, in fact, nothing more than a figment of their imagination. This realization can lead to feelings of betrayal and loss, as the person's faith in something they cherished is shattered.
The metaphor of believing in a ghost underscores the fragility of belief and the pain that accompanies the discovery of its falsehood. It emphasizes the human struggle with faith, truth, and the existential crisis that arises when we confront uncomfortable realities. This sentiment resonates with anyone who has ever wrestled with their convictions and faced the harsh light of truth.
