Siren Head is a fictional humanoid monster created by the horror artist Trevor Henderson in 2018. Standing as a towering, skeletal figure with sirens replacing its head, the creature is known for emitting disturbing noises ranging from air-raid sirens to distorted human voices. It transitioned from a piece of internet horror art into a global phenomenon through indie games, viral TikTok videos, and fan-made animations. In the meme world, Siren Head is often used to represent an impending sense of dread, overwhelming noise, or a massive, inescapable problem that is looming in the background of a seemingly normal situation.
