Hey guess what. I went to a luncheon where Mary Ann Winkowski was the speaker on Halloween. She see's and talks to earth bound spirts and is the person whom the show Ghost Whisperer was created after. She was a consultant on the show. She has a web site, google it, and you can contact her. She will call you back, but this is her busy time she said it will take till after the holidays to get back to you. She lives in NE OH as I do and I've heard her on radio shows. Plus my neighbor is a family friend of her's and knew her before she became popular because of the show. I just got done reading her book When Ghosts Speak. Check it out of the library it's an easy read.
Anywho back to the phone call. When she calls you back on your home phone she is able to see any spirits that are in your home. I find all this very fascinating and definitley believe there are spirts who don't go into the light. Sometimes I feel a breeze over my face as I lay in bed at night. My DH says is the furnance kicking on

..I've also been awakened by someone calling my name.

But other than that if I do have a ghost

I don't notice any negatives from it.
She does say that spirits of your relatives who have crossed over come back and visit you often but they don't create any havoc in your life. She cannot see or talk to these spirits but says they are good. Anyway you can call her whereever you are, not sure if she would come to you, but maybe she knows someone in your area who can help. Because of the show and her popularity she knows a lot of people in the country. Good luck.
