Can we communicate with the dead ?

Americans have always seemed fascinated by the idea of communicating with spirits in another world. Who else can make movies like Ghost? According to a recent study by the Baylor Institute for Studies of Religion, 20% of Americans believe that the living can communicate with the dead. In an online survey of 10,000 Beliefnet members, 77% said they'd felt the presence of a spirit, angel or dead soul.
Both the survey results and the TV statistics indicate that women are more likely to believe it's possible to interact with the spirit world. 46% of women surveyed believed that "the souls of the dead protect the living as spirit guides," compared with 27% of men. Women were also more likely than men to believe that "the dead can hear our prayers or intercede with God on our behalf."
