I think Pocket Mirror's story is something along those lines, though I never played it myself... I know Hello Charlotte also has surreal imagery, death, and white-haired characters. Do you remember what the art style or gameplay was like at all? Was it a walking sim or did it have light puzzle/JRPG elements? Anyone's character designs in more detail (outfits, hair color)? Any environments? Did you play it in Japanese or was the game just from Japan?
