Jennifer Love Hewitt's 'Ghost'

(CBS)  In the new CBS drama "Ghost Whisperer" Jennifer Love Hewitt plays Melinda Gordon, a young newlywed desperate to lead a normal life.

But it's not easy because she also has the ability to see, talk, and help departed spirits seeking closure.

In the premiere episode, the ghost of a lost soldier contacts Melinda. The show is based on the experiences of a "real-life ghost buster," Love Hewitt tells The Early Show co-anchor Hannah Storm. "She is a consultant on the show. We went ghost busting in L.A. together."

The medium actually went to Love Hewitt's 1927 house and found two ghosts, a man and a woman.

"If you start feeling very lethargic and you have throat problems or really bad headaches, a lot of times that can sometimes mean there is nothing wrong with you physically, but also that you have a ghost," says Hewitt.

"They're drawing on your energy. They draw on your upset, on your stress, on your tired, on your emotional and whatever else is going on with you at the time. Because they pull your energy, you feel like you're sick."

Thankfully, Hewitt says, they are now gone.

"She basically asked them if they were ready to go and sort of had this conversation. She talks with them basically, like, in my living room. Then she crossed them over to the light. And I have not had one thing since."

And though Hewitt says she is not sure if this is true or not, she does the same in her show.

"It is about the human spirit," she says. "Each show consists of incredible stories that will inspire people to go live their lives so they don't have any unfinished business. This show teaches viewers not take anything for granted."
