The word “spasm” is often employed as a vivid metaphor for sudden, visceral bursts of physical or emotional intensity in literature. It conveys more than mere muscle contractions, capturing fleeting yet powerful states of terror, pain, anger, and even rapture. Authors describe faces contorted by inexplicable horror [1] or pain that momentarily overtakes a character [2][3][4]. At other times, “spasm” reveals an inner turmoil—a transient shock of grief, desire, or defiance—that disrupts a character’s composure, as seen in moments of sudden, rebellious energy [5][6][7]. This dynamic usage enriches narratives by dramatizing the characters’ inner experiences with a force that is both physical and metaphorical [8][9].
