Create an eerie, dark background with a menacing, toothy grin illuminated in bright white, emerging from the darkness. The eyes are glowing in deep, red light, giving the appearance of a sinister, evil entity lurking in the shadows. The features of the face should be partially hidden, with only the teeth and eyes clearly visible, enhancing the ominous atmosphere. The overall image should evoke a sense of dread and mystery, emphasizing a haunting, ghostly presence.
