About This Book
The author conducts a wide-ranging survey of uncanny experiences, from apparitions and prophetic dreams to somnambulism, trances, and mesmerism, combining medical observation with folklore. He classifies and analyzes causes of spectral and dream phenomena—psychological association, cerebral excitement or congestion, optical and atmospheric effects, narcotics, and coincidence—and relates clinical cases and popular anecdotes. Chapters examine fairy and demon lore, prophetic belief, and stages of sleep, memory, and trance, showing how physiological and mental conditions produce vivid illusions. The work aims to explain mysterious reports through natural and psychological principles while acknowledging the poetic and cultural forces that shape belief.
