Ectoplasm is a supposed physical substance that manifests as a result of spiritual energy or psychic phenomenon. Ectoplasm is associated with the formation of ghosts, & hypothesized to be an enabling factor in psychokinesis. Ectoplasm is produced by physical mediums when in a trance state. This material is excreted as a gauze-like substance from orifices on the medium’s body & spiritual entities and drape this substance over their nonphysical body, enabling them to interact in our physical universe.
