Dreams are very readily excited through impressions made on the special nerves of sensation. Instances are given of persons sleeping with bottles of hot water applied to their feet dreaming of walking on burning lava, or some other hot substance. A patient related to me the particulars of a dream which occurred to him while he was asleep with a vessel of hot water applied to the soles of his feet. He had, just before going to sleep, read in the evening paper an account of the capture of an English gentleman by Italian brigands. He dreamt that while crossing the Rocky Mountains he had been attacked by two Mexicans, who, after a long fight, had succeeded in taking him alive.

On one occasion she dreamed that she was transformed into a bear, and was being taught to dance by being made to stand on hot plates of iron. On another, that the house was on fire, and that the floors were so hot as to burn her feet in her efforts to escape. Again, that she was wading through a stream of water which came from a hot spring in the Central Park.

The pain was not severe, and yet it was sufficient to give rise to the following dream:
