In 1978, Goodman founded The Cuyamungue Institute in an area known as Cuyamungue, New Mexico to continue her research into altered states of consciousness and to hold workshops. After the publishing of "Where the Spirits Ride the Wind: Trance Journeys and Other Ecstatic Experiences" Goodman's following grew, primarily in the US and Germany, among "New Age" and "Neo-Shaman" practitioners as well as scholars in her field. Before her death in 2005, Goodman had published over 40 articles and more than seven books. Her book, "The Exorcism of Anneliese Michel", was the inspiration for the film "The Exorcism of Emily Rose" (in which a fictionalized version of Goodman was played by Shohreh Aghdashloo).
