From India to the Planet Mars : A Study of A Case of Somnambulism With Glossolalia

"From India to the Planet Mars A Study of a Case of Somnambulism with Glossolalia" by Théodore Flournoy is a pioneering work in the field of psychology and parapsychology, published in 1900. It examines the case of Hélène Smith, a medium who claimed to have past lives, including one in India and another on Mars, speaking in invented languages (glossolalia). Flournoy analyzes her trances and visions, exploring the boundaries between psychology, spiritualism, and the unconscious mind, blending scientific inquiry with curiosity about the paranormal.
