In the darkness of the night, I held a dimly lit orange candle lantern and tightly grasped my companion's hand. Guided by two "stewards," we entered the "castle" - the haunted house in the admin building. Tonight, the admin building appeared drastically different from its usual self. Blocks of black curtains formed twisted passages, creating an eerie darkness that felt like bats might fly out at any moment. Faint piano sounds echoed from somewhere, further adding to the sinister and terrifying ambiance. Just upon entering, adjacent classrooms suddenly emitted banging and roaring sounds, and NPCs wearing horrifying masks were sprawled against the glass, causing us to scream in surprise. Frightened but curious, we followed the sound of the piano, holding onto each other's hands, and ventured further in. NPCs, equipped with props, intermittently roared out of the darkness, and terrifyingly realistic props emerged under the faint candlelight. As the piano sounds grew clearer, we cautiously pushed open the classroom door, startled by the "severed arm" hanging at the entrance, while using the candlelight to distinguish the pianist's figure. At this moment, another NPC emerged from the dark corner of the classroom, causing us to panic and flee. Along the way, the sudden appearance of screaming NPCs and terrifying props made us scream continuously as if they had appeared out of nowhere. Being "pursued" throughout, we finally arrived at the exit. Despite knowing that the horrifying masks were worn by familiar classmates, there was still a lingering sense of horror. At the same time, I deeply admired their dedication and professionalism, which provided us with an unforgettable and uniquely eerie Halloween haunted house experience!
