Manifesting Spirits is an ethnographic study of a contemporary trance mediumship development circle in suburban Bristol. The book has a particular emphasis on the ways in which extraordinary experiences had in seances lead to expanded notions of self and consciousness for both mediums and sitters, and the processes by which spirits are manifested in seance situations. Overall, the book makes strides toward the development of a nonreductive anthropology of the paranormal that embraces complexity and pushes beyond established models.
