Note 51 — Chapter III

Dissociation may be defined as a condition in which, in the words of Tannery (Revue Philosophique, October 1898), 'the various organisms of the brain which in the waking state accomplish distinct functions with satisfactory agreement are, on the contrary, in a state of semi-independence.' There is, in Greenwood's words (Imagination in Dreams, p. 41), a 'loosening of mental bonds,' corresponding to the relaxation of muscular tension which also occurs before going to sleep.
