a state of general anesthesia in which the person retains a slight degree of consciousness; can be induced by injection of scopolamine or morphine
Twilight sleep (English translation of the German word D?mmerschlaf) is an amnesic condition characterized by insensibility to pain without loss of consciousness, induced by an injection of morphine and scopolamine, especially to relieve the pain of childbirth. This combination induces a semi-narcotic state which produces the experience of childbirth without pain, or without the memory of pain.
