After-death communication

After-death communications are communications that either are believed to or appear to have been received from a person who has died.

Precise definitions of ADCs vary. According to Bill and Judith Guggenheim, an ADC occurs when a person is "contacted directly and spontaneously by a deceased family member or friend, without the use of psychics, mediums, rituals, or devices of any kind" (Guggenheim 2005).

Psychologist Allan Botkin uses the term induced after-death communication or IADC (Botkin 2005) for his practice of inducing perceived reconnections with key people for grief therapy.

Prevalence of ADCs

"It's estimated that 50-100 million Americans - 20-40% of the population of the United States - have had one or more ADC experiences" (Guggenheim 2005).
