Mientras duermes
Sleep Tight
What if the person who tucks you in each night is the very one you should fear most? In the unsettling thriller Sleep Tight (originally Mientras duermes), an apartment concierge named César makes it his mission to ensure no resident ever truly rests easy. This 2011 psychological horror film peels back the layers of a seemingly ordinary man whose life revolves around secretly poisoning the happiness of others, particularly a cheerful young woman in his building. Blending suspense and dread with chilling realism, the movie explores themes of obsession, misery, and the violation of personal sanctuary. It’s a masterclass in tension, directed with meticulous control that makes every creak of the floorboard feel like a scream. Viewers should watch Sleep Tight for its deeply unsettling atmosphere and a villain whose quiet malevolence lingers long after the credits roll. This isn't just a story about fear—it's about the horror of trust betrayed, and the shadows living right next door.
