Psychorrhagic Diathesis
Formidable term used by psychical researcher F. W. H.
Myers for his theory of phantasmal appearances, a psychic faculty
of detaching elements of personality and transforming by
them a certain part of space into a phantasmogenetic center.
In this center, in a manner not material or optical, the phantasm
of the psychorrhagist appears and may become collectively
visible. (See also apparitions)
