Create an intimate and serene illustration of a person peacefully sleeping in bed. The focus is on a close-up view of their face, softly illuminated by the warm glow of ambient lighting in the room. Their features are relaxed, with a gentle, contented smile hinting at sweet dreams. The eyes are closed, and the expression exudes calm and happiness. The background subtly hints at a cozy bedroom setting, with blurred details of a plush pillow and part of the headboard. Use soft, warm tones for the skin and bedding, emphasizing comfort and tranquility. The lighting is delicate, highlighting the contours of the face while casting gentle shadows, creating a dreamy and soothing atmosphere. Include small details, like a wisp of hair falling naturally across their forehead, to enhance the intimate and personal vibe.
