Indeed it must be that, with the consoling prognosis: “Dysentery will develop, &c.,” I am making fun of Dr. M., for I recollect that years ago he once jokingly told a very similar story of another colleague. He had been called to consult with this colleague in the case of a woman who was very seriously ill and had felt obliged to confront the other physician, who seemed very hopeful, with the fact that he found albumen in the patient’s urine. The colleague, however, did not let this worry him, but answered calmly: “That does not matter, doctor; the albumen will without doubt be excreted.” Thus I can no longer doubt that derision for those colleagues who are ignorant of hysteria is contained in this part of the dream. As though in confirmation, this question now arises in my mind: “Does Dr. M. know that the symptoms of his patient, of our friend Irma, which give cause for fearing tuberculosis, are also based on hysteria? Has he recognised this hysteria, or has he stupidly ignored it?” But what can be my motive in treating this friend so badly? This is very simple: Dr. M. agrees with my solution as little as Irma herself. I have thus already in this dream taken revenge on two persons, on Irma in the words, “If you still have pains, it is your own fault,” and on Dr. M. in the wording of the nonsensical consolation which has been put into his mouth. _We have immediate knowledge of the origin of the infection._ This immediate knowledge in the dream is very remarkable. Just before we did not know it, since the infection was first demonstrated by Leopold. _My friend Otto has recently given her an injection when she felt ill._ Otto had actually related that in the short time of his visit to Irma’s family, he had been called to a neighbouring hotel in order to give an injection to some one who fell suddenly ill. Injections again recall the unfortunate friend who has poisoned himself with cocaine. I had recommended the remedy to him merely for internal use during the withdrawal of morphine, but he once gave himself injections of cocaine.
