In Vladimir Nabokov's "Lolita," the complexity of love and obsession is poignantly expressed through the line, "My heart seemed everywhere at once." This quote reveals the intense emotional turmoil experienced by the protagonist, who finds himself consumed by his feelings. It signifies a state of disarray, where his heart and desires are scattered across various dimensions of longing and regret. The phrase encapsulates the essence of a love that transcends conventional boundaries, illustrating the tumultuous nature of such deep attachment.

This depiction resonates throughout the narrative, showcasing how love can evoke both ecstasy and chaos. The character's heart is not confined to one place but is spread across memories, fantasies, and the person of his affection. Such a sentiment reflects the pervasive theme in "Lolita" of love's duality—it can lift one to great heights while simultaneously leading to profound despair, making it a powerful reflection on the human experience of desire and compulsion.
