I was walking down the street, and a old woman

Bumped into me, the time he run in to me, I felt nervous and scared. I didn’t care about that, so I just walking down the street. But when I was walking, I felt someone is following me, when I turned back the woman appeared, but she was not facing to me. In general, if she is walking or following me, she should facing my back right? But she wasn’t. I started to walk fast. At first I was walking quickly, and then slowly running, and fast run, a while later I went home, and I told my mom the thing that happened, my mom says if anyone saw her, it means that is something will happen, and did tou saw his red Scarflette? No I said, well that is a good thing, if you saw it, it’s totally bad luck. I asked what is the red scarflette? My mom said she was killed by a killer because she was rich, and when she was killed, the bracelet was with her, and someone said the bracelet is her life, and she said that she lost it, she won’t live anymore, but until now, we don’t understand why.
