This unsettling horror film is not overtly scary, but the claustrophobic setting, strange characters, and ambiguous plot create a sense of unease and discomfort that lingers throughout the film. Vivarium follows a young couple looking to buy a home. They become trapped in a suburban nightmare after being lured into a mysterious, uniform housing development with no apparent means of escape.

7 – Signs (2002)

A former minister and his family are forced to confront their deepest fears and beliefs when a series of crop circles appear on their farm, coinciding with the arrival of strange, ominous beings. While not a horror film, Signs‘ slow-building suspense and eerie, otherworldly atmosphere create an unnerving sense of tension and dread, keeping the audience on edge until the film's climactic finale. It is, in my opinion, M. Night Shyamalan's most criminally underrated film.

8 – Safe (1995)
