Synopsis Dreams are part of common experience yet a mystery that is little understood. Psychologists and other who are ignorant of the human being's true constitution, ranging across several subtle levels, are only groping to learn their significance. C. W. Leadbeater an eminent clairvoyant and author of many books, explains in this manual how human consciousness function when the body is asleep and how it is affected by the experiences in the physical and subtle worlds. These experiences take shape as dreams of different kinds-true, prophetic, symbolical, confused and so on. The author emphasizes the importance of mastery over thought processes and lower passions in order to respond to the influences of the true Self within. The last thoughts before going to sleep must be about pure and holy things. Then dreams will not disturb the serene and joyful experience of higher worlds.
