A serene winter beach with soft waves rolling onto the shore under a cloudy gray sky. A person wearing a long coat and scarf walks alone along the beach. Their figure appears multiple times as ghostly afterimages, creating an ethereal and dreamlike effect of motion. The atmosphere is quiet and reflective, emphasizing the cold, tranquil mood of the winter seascape. --sref <https://s.mj.run/SjF1LlQ2TAQ>
