This is an extreme challenge to the psychological capacity of the horror of the soundtrack. The music opens with an extremely eerie, poignant female humming, as if it were a call from the depths of hell. Subsequently, the heavy and depressing low-frequency noise (Drone), harsh discordant strings (Dissonance) and sound effects similar to metal friction continue to interweave and ferment, wrapping the audience in an inescapable sense of suffocation. The most frightening thing is that after a long period of depression, the music will release a very destructive scare sound effect (Jump Scare) without any guard, which completely breaks down the listener’s psychological defense.
