According to Bill Gugenheim, an After-Death Communication, or ADC, is a spiritual experience that occurs when someone is contacted directly and spontaneously by a family member or friend who has crossed over.
An ADC is a direct experience because no psychics, mediums, therapists, rituals, or devices are involved.
And an ADC is a spontaneous event because our deceased loved ones always choose when, where, and how they will contact us.
