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."
While there are a few different forms of mediumship, I work as a mental medium, which means I communicate with spirits through the use of telepathy. Spirits impress my mind and body with thoughts and feelings that come in the form of "clairs." I mentally "hear" (clairaudience), "see" (clairvoyance), "know" (claircognizance) and/or "feel" (clairsentience) messages from spirits. I like to say that I act as the bridge between the spiritual and the physical world, with the intention of healing both worlds.
