Ideoplasm

Another term for ectoplasm, a substance claimed to issue from the body of a materialization medium in a vaporous or solid form, taking on the appearance of phantom forms or limbs. The concept of ideoplasm stems from the investigations of such psychical researchers as the Frenchman Gustav Geley and conveys the additional idea that the substance may be molded by the operators into any shape to express ideas of the medium or of the sitters.
