Well, others have apparently given you the arguement that it is not possible and that is fair, from the point of view of someone who is in tune with all the worlds around her, all children see things they "are not supposed to." With that said, debunk before you go "all in" on the theory as well a parent's reaction to real moments will effect weather they continue to aknowledge these moments. I will give you an example of my son ... last September Papa (greatgpa) passed away, I was with my MIL at a party my SIL was hosting when we got the call from the hospital to get there - we got to the hospital and got the news; I called my hunny and he said I was wondering why he said "I just saw Papa, he said bye-bye" just before he went to bed. Then at the funeral he had another moment with Papa, and a few times he comes and tells me that Papa told him he needs to watch cartoons; when Papa came over he would tell him to watch cartoons and they would each sit in a certain spot - he sits in that exact spot. As far as I am concerned Papa is a nice play mate for him and it does not bother me at all, in fact I love that he visits upon occasion. Like I said debunk however after that listen to what she has to say and accept it.
