We were acquainted with a young lady accustomed to sit up in bed and recite poetry in her sleep, whose mother assured us that she sometimes took cognizance of circumstances which she could not, in any way, account for. On one occasion they had been to a ball; and, after the daughter was in bed and asleep, her mother went quietly into her room, and taking away her dress and gloves deposited them in another room. Presently, as usual, the fair somnambule began talking in her sleep; her mother entered, as usual, into conversation with her; and, at length, asked, "But what have you done with your new ball-dress?" "Why, you know," replied she, "you have laid it on the couch in the drawing-room." "Yes," continued the mother, "but your gloves--what have you done with them?" "You know well enough," she answered, in an angry tone, "you have locked them up in your jewel-box." Both answers were correct; and it may be here observed that somnambulists, if equivocated with in conversation, or in any way played upon, will express themselves annoyed, and betray angry feelings. The truthfulness of sleep-talking may, we apprehend, always be relied on. In this state there is no attempt at evasion; no ingenuity exercised to disguise any thing. The master-mind of Shakspeare--which seems to have divined the secrets of Nature, and illustrated scientific principles before they were discovered by philosophers--recognized this fact, in making Iago thus rouse the jealousy of Othello: "There are a kind of men so loose of soul That in their sleep will mutter their affairs; One of this kind is Cassio. In sleep I heard him say, 'Sweet Desdemona, Let us be wary.'"
