Revelations of the Unconscious in the Life of the Soul from the Spiritual Scientific Point of View

But, dear readers, anyone who compares a hallucination to a dream image is very much mistaken. Above all, it must be emphasized that a person who dreams does not fall into a state through dreaming over which he is powerless with his waking consciousness. The hallucination must be characterized by the fact that the person is powerless against it with his waking consciousness. The hallucination intrudes into the ordinary consciousness, and one must become aware that the reason why this is so is a change, albeit a hidden change, in the human body itself; it is some part of the human body that gives rise to the hallucinations.
