Between 8 November and 31 December 1920 Gustav Geley of the Institute Metapsychique International attended fourteen séances with the medium Franek Kluski in Paris. A bowl of hot paraffin was placed in the room and according to Kluski spirits dipped their limbs into the paraffin and then into a bath of water to materialize. Three other series of séances were held in Warsaw in Kluski's own apartment, these took place over a period of three years. Kluski was not searched in any of the séances. Photographs of the molds were obtained during the four series of experiments and were published by Geley in 1924.[123][124] Harry Houdini replicated the Kluski materialization moulds by using his hands and a bowl of hot paraffin.[125]
The psychical researchers W. W. Baggally and Everard Feilding exposed the British materialization medium Christopher Chambers as a fraud in 1905. A false moustache was discovered in the séance room which he used to fabricate the spirit materializations.[104] The British medium Charles Eldred was exposed as a fraud in 1906. Eldred would sit in a chair in a curtained off area in the room known as a "séance cabinet". Various spirit figures would emerge from the cabinet and move around the séance room, however, it was discovered that the chair had a secret compartment that contained beards, cloths, masks, and wigs that Eldred would dress up in to fake the spirits.[105]
St. Edith Stein, Patron of Europe, converted to Catholicism after reading the autobiography of St. Teresa of Ávila on a holiday in Göttingen in 1921, at the age of 29. One evening Edith picked up an autobiography of St. Teresa of Ávila and read this book all night. "When I had finished the book, I said to myself: This is the truth." She went out the next day to buy a missal and a copy of the Catholic catechism.
Aura readings involve the observation and interpretation of auras.[12] The aura is purported to be a field of subtle, luminous radiation surrounding a person.[13] Psychics have offered aura readings for many years.[citation needed] They claim to have a unique ability to see or sense individual’s auras, however no evidence has ever been provided to substantiate this claim.[citation needed]
Well, here is where things might be a little more “out there” and magical. You see, we are all connected to a collective, universal wisdom and our inner wisdom. And when we read the Tarot cards—and connect with our intuition—we can tap into this universal wisdom. It’s a little like connecting in with the collective mind, not just the individual mind. 
When I am writing and channeling simultaneously, I am very much ‘in the zone’, but far from unconscious. I would describe it more as being in an altered state of consciousness, rather than a ‘trance’. To get into this state I simply put my receptive right brain in the drivers seat and my rational left brain in the passenger seat. There are times when I give my rational mind permission to ask a question (which is usually answered) but, for the most part it is a passive observer of the process. I find it is important not to judge any of the material I’m channeling. I read it with my left brain filter after the channeling has finished.

I have been fortunate enough to work with trance mediums, one especially gifted one, in a therapeutic context for several years now. I personally feel we truly know next to nothing about the mechanisms behind trance channeling and mediumship. Like Edison said, "We don't know one millionth of one percent about anything." I do think it's far more likely to be an integrative both/and rather than either/or pheonomenon with respect to subconscious production vs spirit speakers (to say nothing of tapping the collective unconscious) and that's about all I feel reasonably sure of. Quantum (Unified Field)theories/New Paradigm Science and the like holds promise as far as cracking the code on the the entire spectrum of super-normal phenomena. The study here sounds rudimentary. I would suggest interested readers see the research being done at Windbridge Institue, the Rhine Research Center, and IONS.

ISBN 978-0-7387-1363-2 "One medium of the 1920s, Mina Crandon, became famous for producing ectoplasm during her sittings. At the height of the séance, she was even able to produce a tiny ectoplasmic hand from her navel, which waved about in the darkness. Her career ended when Harvard biologists were able to examine the tiny hand and found it to be nothing more than a carved piece of animal liver."

The psychical researchers Eric Dingwall and Harry Price re-published an anonymous work written by a former medium entitled Revelations of a Spirit Medium (1922) which exposed the tricks of mediumship and the fraudulent methods of producing "spirit hands".[132] Originally all the copies of the book were bought up by spiritualists and deliberately destroyed.[133] In 1923, the magician Carlos María de Heredia revealed how fake spirit hands could be made by using a rubber glove, paraffin and a jar of cold water.[134]
