I wonder that myself. I bet he has seen someone. He quit making fun of me when I told him about the bowls moving and about my Dad's spirit. Unless it was a really noticeable event, I doubt he would tell me. He would just say it was his eyes or the sun or something. He said out loud (loud enough for them to hear) that they were welcome here! Was I surprised! I also think that my oldest saw something when he was still at home, because he believes me. He would not admit it either.
I don't know if it's my son's coping or that they just like what he has in his room. LOL. Micheal is not at all scared, he is kind of excited by them. Before when they were trying to be heard, he got headaches all the time. Immediately after I asked them not to try to connect with him, his headaches stopped. So, I think they are abiding by my rules. but are hoping he will accept them if he sees them. I don't know. Their being here is a really neat thing and I feel privileged.
