I saw this girl on my street and when I heard her name I freaked out

I live in England and I was just walking home from the shop when I saw a pretty looking girl and she had her hair down and when I saw her name tag I freaked out. I don't remember the name but she had bright red hair and her name tag had an unusual name for her hair like "Sarah" or something. She walked behind me and I could hear her walking closer and closer and didn't know what to do and when she got closer I asked her what she wanted and she said she noticed I was walking alone and seen the way I was acting and asked if I was okay. I said no and she asked what was wrong and I told her that in 2010 my family and I went to the forest and got lost and my parents were murdered by a lady with bright red hair and her friends in front of me. I don't know how I got home but I remember calling the police and tell them what happened. She gasped and said her name was Emily and she said she went to the forest and got lost in 2010 and met a lady with bright red hair and she was nice to her and Emily said she had never met a lady like her until she met her. Emily said she never had anyone to tell her story and says she hadn't come clean to anyone about what really happened and she said she would like to talk about it with me because she remembered something about how she met the lady and Emily said that she could have been the lady and she said she isn't saying that but she said what if the lady that killed my parents was nice to her. I said that's impossible and she said what if they went to the forest looking for someone to kill and I said how would she know we were there. Emily told me that she went to the forest with the lady and they settled down and the lady told her and her friends to make a huge noise to scare the kids that were already in there and she said she didn't know what to do because she wanted to say something but they ran off and they would pick a random kid to kill and they didn't kill her and the lady told her to leave but she didn't want to and she cried and said she wanted to stay with them but they told her to go and they didn't know she was still there until she said that she could have been the lady and she said it was a rare name for a red haired person and she said she didn't know if I believed her but she said it was true and I said okay.
