This sound comes from Dead by Daylight and is associated with The Wraith, one of the game’s original killers. Players know it as the audio cue for his Wailing Bell and cloak ability, which warns that he is shifting in or out of invisibility. Because Dead by Daylight became a long-running multiplayer horror game with a strong clip culture, the sound spread into montages, memes and reaction edits. It still gets used because the bell is instantly recognizable to DBD players and clearly signals danger.
