Published in 1910, 'Ghostly Phenomena' by Elliott O'Donnell is a collection of accounts detailing supernatural occurrences and the author's personal experiences with ghosts. O'Donnell categorizes these entities into different types of 'Elementals' and theorizes about their connections to human emotions and illnesses. The book reflects on his early ghostly encounters, including a childhood experience with a grotesque apparition, and explores themes such as spirits appearing before death and their potential warnings of doom.
