Act as a visionary surrealist artist with expertise in dreamlike landscapes. Create a highly detailed, photorealistic yet fantastical desert scene where colossal hourglasses, each [50 feet tall], stand half-buried in golden dunes. The sands are [constantly shifting in impossible patterns], revealing glimpses of [ancient buried ruins] beneath. The sky is a gradient of twilight purples and oranges, with floating islands in the distance. Add subtle surreal touches like [mirror-like pools reflecting upside-down pyramids] and [sand cascading upwards into some hourglasses]. Use dramatic lighting to highlight the textures of cracked glass and wind-sculpted dunes. Style inspiration: Salvador Dalí meets Roger Dean, with a touch of Studio Ghibli's whimsy. 8K resolution, cinematic composition.
