So I just got back from a friends house about an hour ago. It started out innocently enough just doing some card readings as usual and all around just having a great time.My family comes from a long line of Physics and mediums but I personally never really let it in too much. But tonight was different. I saw my friends dead grandmother EXTREMELY clear. I was able to answer questions about her and actually guess right down to the accessories and color of what she was buried in. Needless to say it terrified me. I didn't know anything about her but I was on topic and correct about everything. As the night went on it was almost like she was communicating through me.I didn't just see her but I was able to talk with her.
After I left his house I got an extremely intense head ache and I feel weak.
I just need to know if that's normal.And some advice because I feel insane and don't know what to do about this.
