There is, therefore, both positive and negative proof in favour of my mental and suggestive theory, and in opposition to the magnetic, occult, or ele… - James Braid

It is commonly said that seeing is believing, but feeling is the very truth. I shall, therefore, give the result of my experience of hypnotism in my own person. In the middle of September, 1844, I suffered from a most severe attack of rheumatism, implicating the left side of the neck and chest, and the left arm. At first the pain was moderately severe, and I took some medicine to remove it; but, instead of this, it became more and more violent, and had tormented me for three days, and was so excruciating, that it entirely deprived me of sleep for three nights successively, and on the last of the three nights I could not remain in any one posture for five minutes, from the severity of the pain. On the forenoon of the next day, whilst visiting my patients, every jolt of the carriage I could only compare to several sharp instruments being thrust through my shoulder, neck, and chest. A full inspiration was attended with stabbing pain, such as is experienced in pleurisy. When I returned home for dinner I could neither turn my head, lift my arm, nor draw a breath, without suffering extreme pain. In this condition I resolved to try the effects of hypnotism. I requested two friends, who were present, and who both understood the system, to watch the effects, and arouse me when I had passed sufficiently into the condition; and, with their assurance that they would give strict attention to their charge, I sat down and hypnotised myself, extending the extremities. At the expiration of nine minutes they aroused me, and, to my agreeable surprise, I was quite free from pain, being able to move in any way with perfect ease. I say agreeably surprised, on this account; I had seen like results with many patients; but it is one thing to hear of pain, and another to feel it. My suffering was so exquisite that I could not imagine anyone else ever suffered so intensely as myself on that occasion; and, therefore, I merely expected a mitigation, so that I was truly agreeably surprised to find myself quite free from pain. I continued quite easy all the afternoon, slept comfortably all night, and the following morning felt a little stiffness, but no pain. A week thereafter I had a slight return, which I removed by hypnotising myself once more; and I have remained quite free from rheumatism ever since, now nearly six years.

...have the power of directing or concentrating nervous energy, raising or depressing it in a remarkable degree, at will, locally or generally. That in this state, we have the power of exciting or depressing the force and frequency of the heart's action, and the state of circulation, or generally, in a surprising degree.

It is however possible, by education, to entirely invert the order of these natural phenomena: suppose that the operator [hypnotist] speaks, with each pass or with each movement that he executes, and that he says in advance what will happen, then what he said in advance can take place instead of what would have occurred naturally.
