The effects upon quality of sleep and dreaming of four hypnotics, each at a single dose, have been compared, double-blind, with placebo in ten healthy subjects sleeping at home. They recorded their reports by telephone on being awakened by the experimenter at a pre-arranged convenient time. Clear differences between the treatments were demonstrable.
