The person experiences a white light that appears and fades away,
a circle of intense empty white light inside, a geometric figure
with neither beginning nor end, whose external and internal contours
are out of focus. The light oscillates horizontally, appearing and
disappearing; the sound is dissociated voluntarily. Once one allows
himself to be imbued by both hypnotic fictions, one realises that
they end up coinciding and depending on one another.
