Act as a horror-themed digital artist with expertise in surreal and unsettling imagery. Create a highly detailed, photorealistic image of a haunted carnival mirror that reflects the viewer's darkest fear. The mirror should be ornate, with [tarnished silver filigree] and [cracked, foggy glass], set in a [dimly lit, abandoned carnival booth]. The reflection should be a nightmarish distortion, blending [the viewer's silhouette] with their deepest fear—whether it's [claustrophobic tendrils], [a shadowy doppelgänger], or [a grotesque transformation]. Use eerie lighting, such as flickering carnival bulbs or moonlight, to enhance the dread. The atmosphere should evoke unease, with subtle details like [peeling paint], [cobwebs], or [distant carnival music] faintly audible. Focus on realism with a touch of surreal horror to make the fear palpable.
