Prolific Theosophical writer C. W. Leadbeater explores our Dreams and what's behind them. The most convenient method in which we can arrange the various branches of our subject will perhaps be the following: first, to consider rather carefully the mechanism - physical, etheric and astral - by means of which impressions are conveyed to our consciousness; secondly, to see how the consciousness in its turn affects and uses this mechanism; thirdly, to note the condition both of the consciousness and its mechanism during sleep; and fourthly, to enquire how the various kinds of dreams which men experience are thereby produced.
