"The next morning I sent for the somnambulist, and asked him, without any apparent emotion, of what he had dreamt the preceding night? He was agitated at the question, and answered, 'Father, I had a dream, so strange, that it would give me the deepest pain were I to relate it to you.' 'But I command you to do do; a dream is involuntary; it is a mere illusion,' said I; 'tell it me without reserve.' 'Father,' continued he, 'no sooner had I fallen asleep than I dreamt that you had killed my mother, and I thought that her outraged spirit appeared before me, demanding satisfaction for the horrid deed. At beholding this, I was transported with such fury, that--so it seemed to me--I hurried, like a madman, into your apartment, and finding you in bed there, murdered you with a knife. Thereupon I awoke in a fright, horrified at having made such an attempt, and then thanked God it was only a dream, and that so great a crime had not been committed.' 'That act has been committed,' I then observed, 'further than you suppose.' And thereupon I related what passed, exhibiting at the same time the cuts intended to be inflicted upon me which had penetrated the bed-clothes; upon which the monk fell prostrate at my feet, weeping and sobbing, and imploring to know what act of penance I should sentence him to undergo. 'None; none!' I exclaimed. 'I would not punish you for an involuntary act; but I will dispense with your performing in the holy offices at night for the future; and I give you notice that the door of your cell shall be bolted on the outside when you retire, every evening, and not opened until we assemble to our family matins at break of day.'" Here we may recur to the question with which we set out;--whether persons in somnambulism are partially awake, or in a state of unusually and preternaturally profound sleep? The phenomena we have above referred to--particularly those connected with the insensibility of the body and the organs of the senses--lead us to believe, that in somnambulism there is an increased intensity of sleep, producing an extreme degree of unconsciousness in regard to the physical organization, very similar to that which we find in hysterical, cataleptic, and many other nervous affections. The mental phenomena exhibited in this state are those connected with exaggerated dreams, and as the physiology of dreams is by no means well understood in the healthy state, still less can they be explained under the aspect of disease.
