About Suzanne Segal
Suzanne Segal (1955–1997) was an American writer and teacher about spiritual experience, known for her sudden experience of self-realization which she wrote about in her book Collision With the Infinite: A Life Beyond the Personal Self. In addition to gaining note in the spiritual community, Segal became a model case of the dissociative condition known as depersonalization derealization disorder (DPDR). Along her journey some therapists formally diagnosed her with DPDR, while others did not have clear explanations.
