One of the rituals practised by the Regency was the widdershins or anti-clockwise dance. The next section of Prospero’s Book is headed ‘The Effects of the Widdershins Dance':
One of the effects of an anti-clockwise motion if prolonged and particularly if assisted by humming or some rhythmic device or beat (preferably hypnotic, simple and repetitive) is to promote a sense of displacement. This is of supreme importance. One feels that one is outside oneself or at a little distance from oneself. This is invariably to the left side and somewhat above. We meet this phenomenon in the so-called Near Death Experience, and similar disassociated states. Sometimes it can be drug induced. The known effects of displacement also include the suspension of a linear time sense. (Margin: An effect produced by some poems.) The ability, however dimly, to divine and see a different world and a different order become Present. One of the effects of this state is to trigger small lights, mostly red, which appear and disappear if one is working in the dark. They are lattice nodal points; photons if you like; winking in and out of existence. They are a certain sign of contact between dimensions.
