Annihilation is a 2018 science fiction horror film directed by Alex Garland, adapted from Jeff VanderMeer's 2014 novel. Set inside the Shimmer, a quarantined zone created by a meteor strike, the story follows a team encountering mutated plants and animals shaped by an alien presence that refracts DNA and sound. Clips from the film's most disturbing creature scenes spread widely on YouTube and TikTok, and this short alien vocalisation was lifted as a reusable scare sound for edits, game videos and horror memes.
