Create an image of a serene figure draped in flowing, light fabric that has a subtle shimmer, resembling a soft pastel hue instead of white. The figure should have closed eyes and an expression of tranquility, with delicate wisps of vapor or mist gently curling around their head, evoking a sense of calm and mystery. The background should be a deep, rich color to enhance the ethereal quality, creating a contrast that emphasizes the figure's peaceful presence.
