Link - Cosmic horror has been established as one of the most chilling sub-genres in horror cinema. With a focus on the unknown, isolation, and the human mind, cosmic horror plays on the imaginations of audiences rather than going all out on gore and jump scares. Instead of ghosts, serial killers, or vampires, these stories focus on the endless possibilities of the universe's fictional horrors.
Early 20th-century author H.P. Lovecraft gave Cosmic horror prominence through stories like At the Mountain of Madness, The Hound, and The Call of Cthulhu. The genre can be challenging to pull off in cinema, but plenty of films have tried to capture the terror of the unknown and unimaginable. Everything from stories of paranoia to questions about reality itself has made up cosmic horror in cinema.
Not sure if this counts but it's what popped into my head. I remember being crazy spooked by it as a kid but can't recall much. They eat the past and some people are frozen in time or something?
Either way SKs works are almost all incorporate cosmic horror of some kind.
