that's your professional opinion is it? Not being funny, but unless you have been to one, a proper one, not these mickey mouse mystic megs you see at the fair with crystal balls and ask you a whole lot of questions about your life then tell you what you want to hear Im talking about the REAL mediums who only know you by your first name and you tell them nothing, only then can you have an opinion.
Reason I say that is because the one we go to (had a lot of deaths in the family in the last 10 years) she didn't know us from adam, and we told her nothing. We sat down then she started talking to the space in the middle of the room, and she brought in all the people from my family who had died, she told us what they were thinking, what they were feeling and messages they wanted to give us. She told us who they were by their names, not once did she ask us the names of those who died in our family. and unless she had been stalking me for every minute of the last 10 years there is no way she would know this.
She even said that there was a sprit of a 3 year old boy in the room. she said his name was Jay. My wife burst into tears right in front of us. My wife had a miscarrige 3 and a half years ago and named him jay. and she didnt even tell me that, it was all kept to herself so how the hell could the medium know that when not even i knew?
I know a lot of people say they want to see it for themselves, and i encourage you to, but to completely dismiss it without at least trying it is foolish and your opinion is worthless.
