Apparitions (1953) by G. N. M. Tyrrell
Classic study on apparitional experiences. Tyrell proposes a theory of apparitions as telepathic idea patterns from the persons they represent. He outlines four varieties of apparitional experiences: living agent, crisis, post-mortem and ghosts and explains their phenomenology.
