A thriller/horror movie.

Human-like monsters attack people at night and cut off their hearts. An important thing to recognize the movie: the people in this town cannot speak or cry! So they communicate by writing on paper or using a projector on walls; the investigators conclude that those monsters need 7 human hearts at all. If I’m not mistaken, there were 2 girls (maybe sisters) who used psychokinesis/telekinesis to move furniture to stop the monsters opening doors into their room. This movie is certainly before 2006.
