“
Can Dreams Be Controlled?-Facts prove that they can be, and to a remarkable extent. A large share of emissions occur in the state described by Dr. Carpenter, in which a certain amount of control by the will is possible. This is the usual condition of the mind during morning naps ; and if a person resolutely determines to combat unchaste thoughts whenever they come to him, whether asleep or awake, he will find it possible to control himself not only during this semi-conscious state, but even during more profound sleep.
