1870 Spiritualist 14 Jan. 37/3 One feature running through the whole range of trance-mediumship, is the fact that the media..feel symptoms of the death pains of the communicating spirits.

1961 W. H. Salter Zoar ix. 112 In the early days of trance-mediumship, the view was prevalent that during trance a spirit invaded the medium's body of which it took complete and undivided control... Hence the personalities who claimed to manifest during the trance were called ‘Controls’... In course of time, however, it became desirable to distinguish..spirits who..confined themselves to introducing the Communicators and relaying their messages in the third person [etc.]... It is to spirits of this second kind that the word ‘Control’ is now mostly applied.
