The one aspect of spiritualist practice that's not a hoax is ectoplasmic emanations. A hundred years after the last recorded instance, a young woman once again learns to use telekinesis to form and animate figures made out of her own vaginal mucous -- figures that execute her suppressed desires during her increasingly-frequent bouts of somnambulism. After a mishap involving sleeping pills, she goes into a coma -- and the ectoplasmic figures must be hunted down & dispersed with flash lights.
