you were dared you to explore an abandoned house from a family who all died from committing suicide

The floor beneath you collapses when you step in, you find yourself in a deep watery cave, you see a lady wearing sacrificial gowns facing a wall, you ask her if she got stuck too

unforgivable the lady whispers, her face as if it was mealting off the bones, she reaches to attack you but someone interferes

he comforts the lady as she melts into the water

Young miss who are you?
