Serene Cave Bedroom with Mountain View

Generate a hyper-realistic photo of a serene bedroom interior with a large arched window revealing a breathtaking view of snow-capped mountains and a tranquil lake under a soft, blue-gray sky with a visible moon. The room is carved into a rocky structure, with rough stone walls and a minimalist bed setup on a raised platform, accompanied by spherical bedside lamps. Incorporate natural lighting, realistic materials, and subtle shadows to enhance the ambiance. The scene should evoke a sense of calmness and connection to nature.
