2 way conversations with the departed...

My father passed away on 10/10/01 and continues to communicate with me through my wife while she is asleep. These are 2 way coversations and can last up to 20 minutes. He speaks to me in his voice, not that of my wife and makes references to things she could not possibly know. I have recently been told by an "expert" on these matters that this has never been documented before and could not possibly be true. On a related note, my wife is a seizure patient with what several neurologists have descibed as the "most bizarre EEG they have ever seen in their careers". And yet she functions perfectly with the assistance of medicines and you would never know. I beleive that their are certain parts of her brain that are ripe with brain wave activity that are not normally functional on most people.
