Shh, Don't Make a Sound

At midnight in an old apartment building, the voice-activated lights in the corridor suddenly failed collectively. Seven people living on different floors received a note at the same time with only three words on it: "Shh, be quiet." The first person to break the silence was the single mother on the fifth floor. The moment she turned on the light for her crying child, the entire door and the person disappeared from the corridor, leaving only a humanoid outline bleeding on the wall. The remaining people were suspicious of each other in the dark, but did not dare to make any sound - some people found that every time the breathing sound exceeded 30 decibels, a twisted black shadow would pass outside the window; some people saw the neighbor's face changing into his own appearance behind the peephole; a retired professor who lived on the top floor used lip reading to piece together clues and found that the building's architectural drawings were actually spliced ​​together in the shape of seven people's ribs. The music festival that resulted in the disappearance of hundreds of people ten years ago, the corpses that disappeared in the hospital morgue, and even the frequency of the heart beating at this moment all confirm the same horrific truth - they were never "seven people".
