Mom?

A first-person perspective moves through a dark, dilapidated building, with the character calling out "мама?" and "МАМА ТЫ ГДЕ" while navigating dimly lit hallways and rooms. The sequence culminates in a sudden, frantic jump scare as a hand slams against a door, accompanied by a scream and the text "MA-MAAAAAAAAAA" and "MMMMMMMMMMMMM" as the camera jerks violently.
