[Footnote 92: More than ten years later, the same dreamer, who had entirely forgotten the circumstances of this dream, again had a vivid dream of murder after eating pheasant at night; this time it was she herself who was to be killed, and she awoke imagining that she was struggling with the would-be murderer.] [Footnote 93: F. Greenwood, _Imagination in Dreams_, p. 31.] [Footnote 94: Dreams of railway travelling, and especially of losing trains, are not always associated with headache or any other recognisable condition. They constitute a very common type of dream not quite easy to explain. Dr. Savage mentions, for instance, that in his own case scarcely a week passes without such a dream, though in real life he scarcely ever loses a train and never worries about it. Wundt considers that the dreams in which we seek something we cannot find or have left something behind are due to indefinite coenaesthesic disturbances involving feelings of the same emotional tone, such as an uncomfortable position or a slight irregularity of respiration. I have myself independently observed the same connection, though it is not invariably traceable.] [Footnote 95: E. H. Clarke, _Visions_, p. 294.] [Footnote 96: An amusing, though solemn, interpretation of an ordinary dream of murder, railway travelling, and impending death, as experienced by Anna Kingsford, is furnished by her friend and biographer, Edward Maitland, _Anna Kingsford_, vol. i. p. 117.] [Footnote 97: Various opinions in regard to morality in dreams are brought together by Freud, _Die Traumdeutung_, pp. 45 _et seq._] [Footnote 98: Head ('Mental Changes that Accompany Visceral Diseases,' _Brain_, 1902, p. 802) refers to the association between visceral pain and the anti-social impulses, and thinks that the viscera, being part of the oldest and most autonomic system of the body, appear in consciousness as 'an intrusion from without, an inexplicable obsession.'] [Footnote 99: 'In my dreams,' W. D. Howells remarks, 'I am always less sorry for my misdeeds than for their possible discovery' ('True I talk of Dreams,' _Harper's Magazine_, May 1895).] CHAPTER VI AVIATION IN DREAMS Dreams of Flying and Falling--Their Peculiar Vividness--Dreams of Flying an Alleged Survival of Primeval Experiences--Best explained as based on Respiratory Sensations combined with Cutaneous Anaesthesia--The Explanation of Dreams of Falling--The Sensation of Levitation sometimes experienced by Ecstatic Saints--Also experienced at the Moment of Death.
