Create a highly detailed and unsettling scene of a demonic-like possession involving a Grey alien. The alien is short, with a large, bulbous head and huge, black, almond-shaped eyes that reflect a cold, emotionless intelligence. Its skin is smooth and pale, almost translucent, with faint veins visible beneath the surface. The alien is standing in a dark, shadowy room, its slender, spindly fingers pressed against the forehead of a terrified human, who is in the throes of possession. The human’s face is twisted in agony, with their mouth open in a silent scream, eyes glowing an unnatural, piercing white. Dark energy tendrils, almost like black smoke, swirl around the human’s body, seeping into their skin as if the alien is injecting malevolent power into them. The room is dimly lit by a single flickering light, casting sharp, dramatic shadows that exaggerate the horror of the scene. Arcane symbols and ancient sigils are etched into the walls
