Psychic or Medium
A psychic, or medium, is a person who professes the ability to experience what they or others believe is contact with spirits of the dead or entities such as angels.
The role of the psychic or medium is to attempt to to communicate with spirits who have messages to share with non-mediums. Mediums claim the abilities to listen to and relate conversations with spirit voices, go into a trance and speak without knowledge of what is being said, allow a spirit to control their body and speak through it, relay messages from the spirits to those who wish to contact them with the help of a physical tool, such as a writing instrument. It has also been referred to, in some uses, as channeling, or receiving messages from a 'teaching-spirit.'
