Mediumship can be distinguished as two basic types: 

Mental Mediumship 

Physical Mediumship 

Mental mediumship involves the relating of information, through communication, via the varied aspects of thought transference, or mental telepathy. Mental telepathy is the relaying of information via thought, without using any of the five physical senses. Mental mediumship takes place within the consciousness of the medium. The results are expressed verbally and must pass through the medium's mouth. Because of its telepathic nature, mental mediumship is sometimes referred to as telepathic mediumship.
