A gentleman, two days before an attack of hemiplegia, dreamed that he was cut in two exactly down the mesial line, from the chin to the perineum. By some means union of the divided surfaces was obtained, but he could only move one side. On awaking, a little numbness existed in the side which he had dreamed was paralyzed. This soon passed off, and ceased to engage his attention. The following night he had a somewhat similar dream, and the next day, toward evening, was seized with the attack which rendered him hemiplegic. Another dreamed one night that a man dressed in black and wearing a black mask came to him and struck him violently on the leg. He experienced no pain, however, and the man continued to beat him. In the morning he felt nothing, with the exception of a slight headache. Nothing unusual was observed about the leg, and all went on well, until on the fifth day he had an apoplectic attack, accompanied with hemiplegia, including the leg which he had in his dream imagined to have been struck. A lady, aged forty, who had been a great sufferer from rheumatism for many years, dreamt one afternoon, while sitting in her chair in front of the fire, that a boy threw a stone at her, which, striking her on the face, inflicted a very severe injury. The next day violent inflammation of the tissues around the facial nerve as it emerges from the stylo mastoid foramen set in, and paralysis of the nerve followed, due to effusion of serum, thickening, and consequent pressure. A young lady dreamt that she was seized by robbers and compelled to swallow melted lead. In the morning she felt as well as usual, but toward the middle of the day was attacked with severe tonsillitis. A young man informed me that a day or two before being attacked with acute meningitis, he had dreamed that he was seized by banditti while traveling in Spain, and that they had taken his hair out by the roots, causing him great pain.
