There are dreams which may be called visions. They are reflections; reflections of persons, of their minds, of worlds, of planes on which the mind has become focused. If the mind is focused on a certain world, then the dreams are of that world. If a person is focusing his mind upon himself, then his own thoughts come to him. If the mind is focused on a certain person, then that person and what is within him is reflected in the dream. If the mind is focused on a certain plane of being, then the conditions of that plane are reflected upon the mind. The deeper one goes into this subject, the more one finds that in the understanding of the dream - its nature, its mystery, its character - one understands the secret of the whole life.
