In these cases what is only a silly fancy seems to produce an effect which is not merely fanciful;--which is objective, measurable, and capable of causing long and serious disablement. This result, however, is quite accordant with my view of what I have termed the _hypnotic stratum_ of the personality. I hold, as our coming discussion of hypnotism will more fully explain, that the region into which the hypnotic suggestion gives us access is one of strangely mingled strength and weakness;--of a faculty at once more potent and less coherent than that of waking hours. I think that in these cases we get at the subliminal self only somewhat in the same sense as we get at the supraliminal self when the "highest-level centres" are for the time inoperative (as in a dream) and only "middle-level centres" are left to follow their own devices without inhibition or co-ordination. I hold that this is the explanation of the strange contrasts which hypnosis makes familiar to us--the combination of profound power over the organism with childish readiness to obey the merest whims of the hypnotiser. The intelligence which thus responds is in my view only a fragmentary intelligence; it is a dreamlike scrap of the subliminal self, functioning apart from that self's central and profounder control. What happens in hypnotism in obedience to the hypnotiser's caprice happens in hysteria in obedience to the caprice of the hypnotic stratum itself. Some middle-level centre of the subliminal self (to express a difficult idea by the nearest phrase I can find) gets the notion that there is an "anæsthetic bracelet," say, round the left wrist;--and lo, this straight-way is so; and the hysteric loses supraliminal sensation in this fantastic belt. That the notion does not originate in the hysteric's supraliminal self is proved by the fact that the patient is generally unaware of the existence of the bracelet until the physician discovers it. Nor is it a chance combination;--even were there such a thing as chance. It is a dream of the hypnotic stratum;--an incoherent self-suggestion starting from and affecting a region below the reach of conscious will. Such cases are most instructive; for they begin to show us divisions of the human body based not upon local innervation but upon ideation (however incoherent);--upon intellectual conceptions like "a bracelet," "a cross,"--applied though these conceptions may be with dreamlike futility.
