Create an image of an Envision structure that evokes an atmosphere of dread and mystery. The architecture should challenge perceptions of safety and comfort, with towering, labyrinthine forms that seem to loom over the viewer. Stark, angular lines and oppressive geometries twist and distort, giving the structure an unsettling, otherworldly presence. Shadows play in unnatural ways, and the building's scale feels disorienting, as if it could collapse or shift at any moment. The environment should feel isolated, with dim, almost suffocating lighting, and elements like fog, cracks in the walls, or broken windows adding to the eerie mood. The design should blur the line between the familiar and the terrifying, making the viewer question the true purpose of the space.
