Place it at the exact moment a reveal lands in your edit, after an Inception Horn, then follow it immediately with the FNAF Jumpscare Scream for a second hit in the same sequence.
About this sound
This is a short, sharp jumpscare sound effect lasting about 1.6 seconds, built around a sudden harsh burst that hits without warning. It feels tense and startling, the kind of jolt that makes a quiet moment turn frightening in an instant. It comes from the demo for TRTF 5, a fan-made game in the Five Nights at Freddy's style.
