The medium Henry Slade was caught in fraud many times throughout his career. In a séance in 1876 in London Ray Lankester and Bryan Donkin snatched his slate before the "spirit" message was supposed to be written, and found the writing already there. Slade also played an accordion with one hand under the table and claimed spirits would play it. The magician Chung Ling Soo revealed how Slade had performed the trick.
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. 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. https://drive.google.com/file/d/1kJnhZlLDkOvmq2iOrphoSIgGSld-kvX2/view?usp=sharing
^ LeCron, Leslie; Bordeaux, Jean (1970). Hypnotism Today. Wilshire Book Co. p. 278. ISBN 0-87980-081-X. When in a trance ... the medium seems to come under the control of another personality, purportedly the spirit of a departed soul, and a genuine medium undoubtedly believes the 'control' to be a spirit entity ... In the trance, the medium often enters a cataleptic state marked by extreme rigidity. The control then takes over, the voice may change completely ... and the supposed spirit answers the questions of the sitter, telling of things 'on the other plane' and gives messages from those who have 'passed over.' https://drive.google.com/file/d/19XBpCeNfCJAhAffoBmEKrOMPHlCPQ1uy/view?usp=sharing
Twin flames is a spiritual concept and is the strongest spiritual connection that can occur between two people. Twin flames are believed to occur when a single soul is divided. This separation of twin flames causes some to refer to your twin flame as being the other half of your soul, as you, in turn, are the other half to theirs. Others, however, say that each twin flame is a complete soul in and of itself but that it is a perfectly matched mirror to its counterpart. A twin flame will also be a soulmate, though a soulmate is not always a twin flame. You can only have one twin flame.
