APPENDIX DREAMING AND HYPNOSIS I am assured that a lady of a well-known court saw in a dream and described to her friends the person she afterwards married, and the hall in which the betrothal was celebrated; and she did this before she had seen or known either the man or the place. They attributed the circumstance to some indefinite secret presentiment; but chance may produce this effect, since it is quite rare that it happens; besides, dream-images being somewhat obscure, there is more liberty in connecting them afterwards with certain others.—GOTTFRIED WILHELM LEIBNIZ
