I need advice about a strange, scary situation

For context; i am a trans male teenager

I'm having a strange situation that I feel might be negative and I can't understand why this happening or what is behind it. I met this lady at a tarot group (it was her first time going) and the first thing she says to me is that my ancestors are trying to communicate with me. She offered to be my partner for tarot reading time and started talking as and mentioning things that I haven't told anyone there, or anyone other then family and friends for that matter. She told me that she is indigenous too and how she was much like me when she was a kid, which is weird considering I have very light skin and people often mistake me for being white,and she just looked like a little old white lady. She continued on to mention things about my personality and my internal struggles that I don't tell anyone, and at one point she mentioned that I had gone to a very very specific place which I had gone to 2 days before. Nobody would know that except my mom and here this random old lady that I've met for the first time knows about my trip. She told me to come over to her house so we can review the cards together and gave me her card so I can contact her. As I am a minor she offered to meet up with me and my mom first to prove that she's a safe person. As we were on a walk she went on and on about herself and how she is very spirituality gifted and how she knows that some people at the tarot group don't actually know what they are doing, and such, she casually calls me by my deadname that NOBODY knows except my mom and sister. I felt fear and panic and I have no idea what's happening. My mom told my sister about and my sister said she had a very bad feeling about the lady and my mom said the same, my sister said she think something evil is trying to harm me. I don't understand this and I have a bad feeling. What do you think is happening?
