Place this clip at the peak of a horror sequence, after a quiet build-up, then follow it with the FNAF Jumpscare Scream for a second hit before cutting to the reaction shot.
About this sound
This is a sped-up version of Golden Freddy's scream, a harsh, distorted shriek that lasts about four seconds and hits harder because the faster pace leaves no time to brace for it. It feels sudden, alarming and gleefully unsettling, like a jumpscare arriving a beat early. It comes from Five Nights at Freddy's, where the character's appearance is tied to a sudden, frightening attack.
