Harry Potter trapped in a dimly lit dungeon, surrounded by an eerie glow that casts intricate shadows on the ancient stone walls, his glasses reflecting the dynamic light. The scene is highly detailed and photorealistic, with an extreme nightmare version twist. Magical energies pulse around him, merging the mystical with the creepy. The atmosphere evokes a fusion of H. R. Giger's biomechanical surrealism, Jean Ansell's intricate fantasy elements, and Justin Gerard's vibrant world-building. Ghostly apparitions linger, their translucent forms adding a chilling touch to the dark, enchanted setting.
