Prejudice is pictured as a foul, ghostly fog that tightens around the speaker like a noose, shrinking her world. It chokes off her urge to fly, dance, or break free and throws her rebellious spirit back into a body that feels like a clay shell. The mood is heavy and suffocating, full of blocked movement and silence.
But underneath that crust of silence, a volcano is seething. The speaker compares her hidden anger to Mount Etna: the fire may look asleep, but it never dies. The ending leaves you with a sense of smoldering defiance, not defeat—an oppressed person whose inner heat is only waiting to erupt.
