I suddenly became strangely inebriated. The external world
became changed as in a dream. Objects appeared to gain inrelief;
they assumed unusual dimensions; and colors became more glowing.
Even self-perception and the sense of time were changed. When the
eyes were closed, colored pictures flashed past in a quickly changing
kaleidoscope. After a few hours, the not unpleasant inebriation,
which had been experienced whilst I was fully conscious, disappeared.
what had caused this condition?
