Among the most definite claims of the evil deeds that may be compelled during hypnotic sleep is that of Dr. Luys, whom we have already seen as being himself deceived by professional hypnotic subjects. Says he: “You cannot only oblige this defenseless being, who is incapable of opposing the slightest resistance, to give from hand to hand anything you may choose, but you can also make him sign a promise, draw up a bill of exchange, or any other kind of agreement. You may make him write an holographic will (which according to French law would be valid), which he will hand over to you, and of which he will never know the existence. He is ready to fulfill the minutest legal formalities, and will do so with a calm, serene and natural manner calculated to deceive the most expert law officers. These somnambulists will not hesitate either, you may be sure, to make a denunciation, or to bear false witness; they are, I repeat, the passive instruments of your will. For instance, take E. She will at my bidding write out and sign a donation of forty pounds in my favor. In a criminal point of view the subject under certain suggestions will make false denunciations, accuse this or that person, and maintain with the greatest assurance that he has assisted at an imaginary crime. I will recall to your mind those scenes of fictitious assassination, which have exhibited before you. I was careful to place in the subject’s hands a piece of paper instead of a dagger or a revolver; but it is evident, that if they had held veritable murderous instruments, the scene might have had a tragic ending.” Many experiments along this line have been tried, such as suggesting the theft of a watch or a spoon, which afterward was actually carried out. It may be said at once that “these laboratory crimes” are in most cases successful: A person who has nothing will give away any amount if told to do so; but quite different is the case of a wealthy merchant who really has money to sign away.
