It Is Said That Red Rope Wards Off Evil Spirits

I inherited a red string bracelet from my grandmother. Before she died, she repeatedly warned: "Nanny, no matter what happens, never untie it." The first night I moved into my new apartment, I saw a woman in white standing behind me in the mirror. The red rope suddenly tightened, causing my wrist to hurt. The next day, my downstairs neighbor asked me: "Why were you walking back and forth in the living room last night, wearing a white skirt?" But I lay in bed all night and didn't move.
