Between 1820 and 1826, Friedrich Schlegel wrote an extensive diary about the magnetic treatments of Cäcilia P., Franziska Lesiowska, Marie Trojan and Marie Schmidt (or Marie Albrecht?): Over 300 pages of posthumously published magnetic fanfiction - 4 interchangeable role models of seers whose personal stories are as absent as their gazes. Schlegel used his meticulous records of his patients' trance visions to piece together a paranoid, detailed and mystical cosmology from various mythologies.
 
In 1834, Dr John Elliotson, a staunch supporter and advocate of the medical application of mesmerism, conducted an experiment on three hypnotised young women, which Michael Faraday witnessed. What Faraday observed was an apparent synchronisation or form of communication between the girls in trance. A communication not so much as an exchange of words, but similar to electrical signals sent back and forth between devices.

In the historical laboratory of mesmerism, telepathy and spiritualism, the nervous, hysterical, childish, colonised and non-male body becomes a technological tool to amplify signals and perceptions. People in trance see the inside of the body, make diagnoses for themselves and other patients or see into space - in each case deeper and further than the technology of their time is capable of.
