Create an interior design of a bedroom that resembles an organic stone shape with some sharp features, giving the appearance of being carved from a white cave. Use a neutral color palette with touches of warm colors, focusing on white and beige tones. The design should include smooth, flowing lines and natural textures, creating a cozy and serene atmosphere. Incorporate elements that enhance the cave-like feel, such as recessed lighting, natural stone details, and soft, inviting bedding.
