Well, I don't know. But I do have a friend who is able to read other peoples minds. I found this out last sunday. When ayaris was reading my mind, my head started vibrating, I then look at her and say to her in my head "If you don't stop, I'm going to run away from you to six flags and jump off a rollar coaster" and then she started laughing, LOL! So, when your head is vibrating, you'll then know if someone's reading your mind.
