Having had contact with people who have passed, some that I don't know if I am related to on this earthly plane, I see no reasion that any spirit can not contact just whom they please. These so called "personalities" are just the same as you and I once they die. Do some think that these beings are really something more special over there. ( in reality over there is really over here) If the spirit wants to make contact, then that contact can be made with who ever is ready to have the contact and is able to except the reality of it. In the sprit world there is no "class" difference between us. Just those who are further along on their quest. None of that my spirits better than your spirit stuff or we don't communicate with those sort of spirits, they arn't good enough.
