had extraordinary vivid dreams which developed from night to night, and these appeared in the waking consciousness; at first as obscure illusions, next as real hallucinations, but they never reached the plastic clearness of S. W.'s visions. For instance, she once saw in a dream a black dæmonic figure at her bedside in animated conversation with a white, beautiful figure, which tried to restrain the black one; nevertheless the black one seized her and tried to choke her, then she awoke. Bending over her she then saw a black shadow with a human contour, and near by a white cloudy figure. The vision only disappeared when she lighted a candle. Similar visions were repeated dozens of times. The visions of the other two sisters were of a similar kind, but less intense. This particular type of attack with the complete visions and ideas had developed in the course of less than a month, but never afterwards exceeded these limits. What was later added to these was but the extension of all those thoughts and cycles of visions which to a certain extent were already indicated quite at the beginning. As well as the "great" attacks and the lesser ones, there must also be noted a third kind of state comparable to "lapse" states. These are the _semi-somnambulic states_. They appeared at the beginning or at the end of the "great" attacks, but also appeared without any connection with them. They developed gradually in the course of the first month. It is not possible to give a more precise account of the time of their appearance. In this state a fixed gaze, brilliant eyes, and a certain dignity and stateliness of movement are noticeable. In this phase S. W. is herself, her own somnambulic ego.
