It suggests that the continuous dream-life which we must suppose to run concurrently with our waking life is potent enough to effect from time to time enough of dissociation to enable some element of the personality to be perceived at a distance from the organism. How much of consciousness, if any, may be felt at the point where the excursive phantasm is seen, we cannot say. But the notion that a mere incoherent quasi-dream should thus become perceptible to others is fully in accordance with the theories suggested in this work. For I regard subliminal operation as _continuously_ going on, and I hold that the degree of dissociation which can generate a perceptible phantasm is not necessarily a profound change, since that perceptibility depends so largely upon idiosyncrasies of agent and percipient as yet wholly unexplained. That special idiosyncracy on the part of the agent which tends to make his phantasm easily visible has never yet, so far as I know, received a name, although for convenience' sake it certainly needs one. I propose to use the Greek word φυχορραγὡ, which means strictly "to let the soul break loose," and from which I form the words _psychorrhagy_ and _psychorrhagic_, on obvious analogies. When I say that the agents in these cases were born with the _psychorrhagic diathesis_, I express what I believe to be an important fact, physiological as well as psychological, in terms which seem pedantic, but which are the only ones which mean exactly what the facts oblige me to say. That which "breaks loose" on my hypothesis is not (as in the Greek use of the word) the whole principle of life in the organism; rather it is some psychical element probably of very varying character, and definable mainly by its power of producing a phantasm, perceptible by one or more persons, in some portion or other of space. I hold that this phantasmogenetic effect may be produced either on the mind, and consequently on the brain of another person--in which case he may discern the phantasm somewhere in his vicinity, according to his own mental habit or prepossession--or else directly on a portion of space, "out in the open," in which case several persons may simultaneously discern the phantasm in that actual spot.
