Similarly in insanity we have an even more constant and pronounced tendency for the subject to attribute his own sensations to imaginary individuals, and to create personalities out of portions of the real personality. All the illusions, delusions, and hallucinations of the insane are merely the manifold manifestations of this tendency. Without it the insanity would not exist. It is not because he is subjected to unusual sensations--visionary, auditory, tactile, olfactory, visceral, etc.--that a man is insane. It is because he creates imaginary personalities to account for these sensations; if his food tastes strange some one has given him poison if he hears a strange voice it is some one communicating with him by telephones or microphones or hypnotism; if he feels a strange internal sensation it is perhaps because he has another person inside him. The case has even been recorded of a man who attributed any feeling he experienced, even the most normal sensations of hunger and thirst, to the people around him. It is exactly the same process as goes on in our dreams. The sane man, the normal waking man, may experience all these strange sensations, but he recognises that they are the spontaneous outcome of his own organisation. We may, however, advance a step beyond this position. This self-objectivation, this dramatisation of our experiences, is not confined to sleep and to pathological conditions which resemble sleep. It is natural and primitive in a far wider sense. The infant will gaze inquisitively at its own feet, watch their movements, play with them, 'punish' them; consciousness has not absorbed them as part of the self.[174] The infant really acts and feels towards the remote parts of his own body as the adult acts and feels in dreaming. We are reminded of the generalisation of Giessler that dream consciousness corresponds to the normal psychic state in childhood, while sleeping subconsciousness corresponds to the embryonic psychic state; so that the dream state represents the renascence of the ego disentangling itself from the impersonal sensations and indistinct images of the embryonic stage of life. That sleeping consciousness is the primitive embryonic consciousness is, indeed, indicated, it has often seemed to me, by the fact that in many animals the embryonic position is the position of rest and sleep. Ducklings and chicks in the shell have their heads beneath their wing. The dog lies with his feet together, head flexed, and hind-quarters drawn up. Man, alike in the womb and asleep, tends to be curled up, with the flexors predominating over the extensors.
