If you’re tired of sanitized Hollywood thrillers and crave something that feels like a fever dream you can’t wake up from, let me take you back to 2015 and a little film that slipped through the cracks: Ma Folie .

Directed by the enigmatic Élise Vasseur (in her sophomore feature), Ma Folie is not a horror film in the traditional sense—it’s a psychological pressure cooker. Set against the rain-slicked streets of Lyon and the claustrophobic interiors of a crumbling art commune, the film follows (a stunning performance by Marguerite Thierry), a 28-year-old archivist who begins losing her grip on reality after inheriting a trunk of unsent love letters from a grandmother she never knew. The Plot (Without Spoilers) The tagline on the original French poster read: “L’amour n’est pas une folie. La possession, si.” (Love isn’t madness. Possession is.)
