Somnambulism, or, as it has been called, noctambulation, is a curious phase of nocturnal cerebration analogous to the hypnotic state, or double consciousness occasionally observed in epileptics.

Men have employed anxious months in search of that which, in a freak of noctambulation, was hidden by their own hands.
