Source passage

Source text · mention only

But it is certain, on the other hand, that with a large percentage of persons profound and prolonged sleep can be induced, in _any_ bodily condition, by simple suggestion. Hypnosis, indeed (as Wetterstrand and others have shown) may be prolonged, with actual benefit to the sleeper, far beyond the point which the spontaneous sleep of a healthy subject ever reaches. A good subject can be awakened and thrown into hypnosis again almost at pleasure, and independently of any state either of nutrition or of fatigue. Such sleep belongs to those phenomena which we may call nervous if we will, but which we can observe or influence from the psychological side alone.
