The protagonist in "Mudwoman" by Joyce Carol Oates experiences a profound sense of isolation, particularly in the context of swimming. Surrounded by others who are immersed in the aquatic activity, she feels a deep disconnection from those around her. This dichotomy creates a sense of loneliness that contrasts sharply with the physical presence of other swimmers.

Her thoughts, likened to froth on the water's surface, bubble up amidst a chemical smell, emphasizing the disorienting nature of her solitude. The water, although lively with motion, becomes a metaphor for her internal struggle, where external chaos fails to mask her internal feelings of being cut off and alone.
