 organic sensations on the determination of the resulting dream. He says (p. 34): "If any organic apparatus, which during sleep normally participates in the expression of an affect, for any reason merges into the state of excitation to which it is usually aroused by that affect, the dream thus produced will contain presentations which fit the affect." Another rule reads as follows (p. 35): "If an organic apparatus is in a state of activity, excitation, or disturbance during sleep, the dream will bring ideas which are related to the exercise of the organic function which is performed by that apparatus."

Mourly Vold has undertaken to prove experimentally the influence assumed by the theory of bodily sensation for a single territory. He has made experiments in altering the positions of the sleeper's limbs, and has compared the resulting dream with his alterations. As a result he reports the following theories:—

1. The position of a limb in a dream corresponds approximately to that of reality, i.e. we dream of a static condition of the limb which corresponds to the real condition.

2. When one dreams of a moving limb it always happens that one of the positions occurring in the execution of this movement corresponds to the real position.

3. The position of one's own limb may be attributed in the dream to another person.

4. One may dream further that the movement in question is impeded.

5. The limb in any particular position may appear in the dream as an animal or monster, in which case a certain analogy between the two is established.

6. The position of a limb may incite in the dream ideas which bear some relation or other to this limb. Thus, e.g., if we are employed with the fingers we dream of numerals.

Such results would lead me to conclude that even the theory of bodily sensation cannot fully extinguish the apparent freedom in the determination of the dream picture to be awakened.
