Tracy, that's a lot of visitations!
I used to get messages during healing sessions too. I think there's something about being in a person's energy for an hour, in such a gentle and thoughtful way, that it makes that communication easier for both the spirit and the channel.
So one time I had this guy come in to see me for a massage. I knew ahead of time who he was, and that another client had referred him to me because he was interested in talking about afterlife communication.
So, I just get started on the massage, and he says to me "I came here today because I've heard you give a special service." (yes, he used the word "service" LOL)
So, keep in mind, this was a massage session

I paused for just a split second, because any other client coming to me for a massage who I've never met before would have been given the boot about this point!!! But then I remembered he was interested in the paranormal. I continued with the massage, and yes, a spirit did come through for him.
It's like the most awesome story ever!
