Place it in the middle of a horror edit, after a door knocking sound and before the reveal. Follow it with a dramatic dun dun dun sting to mark the moment the face is seen, then add a metal pipe clang as the scene cuts away.
About this sound
An 18-second recording of drawn-out crying tied to SCP-096, a humanoid figure from SCP Foundation fiction. Listeners hear lonely, grief-stricken wails that feel tense and unsettling, as if danger is close behind them. The figure is known as the Shy Guy, a passive creature that cries until its face is seen, then turns violently agitated.
