Oliver Sacks Hallucinations Quotes

She now receives love, attention, and invisible presents from a hallucinatory gentleman who visits faithfully each evening.

Given her deafness, the auditory part of the brain, deprived of its usual input, had started to generate a spontaneous activity of its own, and this took the form of musical hallucinations, mostly musical memories from her earlier life. The brain needed to stay incessantly active, and if it was not getting its usual stimulation..., it would create its own stimulation in the form of hallucinations.

To live on a day-to-day basis is insufficient for human beings; we need to transcend, transport, escape; we need meaning, understanding, and explanation; we need to see overall patterns in our lives. We need hope, the sense of a future. And we need freedom (or at least the illusion of freedom) to get beyond ourselves, whether with telescopes and microscopes and our ever-burgeoning technology or in states of mind which allow us to travel to other worlds, to transcend our immediate surroundings. We need detachment of this sort as much as we need engagement in our lives.

What they are able to imagine becomes more real to them.

Studies by Andrew Newberg and others have shown that long-term practice of meditation produces significant alterations in cerebral blood flow in parts of the brain related to attention, emotion, and some autonomic functions.

And one day the mind leaps from imagination to hallucination, and the congregant hears God, sees God.

One does not see with the eyes; one sees with the brain, which has dozens of different systems for analyzing the input from the eyes.

We now know that memories are not fixed or frozen, like Proust’s jars of preserves in a larder, but are transformed, disassembled, reassembled, and recategorized with every act of recollection. —Oliver Sacks, Hallucinations

And then, as if thrown by a giant paintbrush, there appeared a huge, trembling, pear-shaped blob of the purest indigo. Luminous, numinous, it filled me with rapture: It was the color of heaven, the color, I thought, which Giotto had spent a lifetime trying to get but never achieved—never achieved, perhaps, because the color of heaven is not to be seen on earth.

This usually occurs at the moment when my head hits the pillow at night; my eyes close and … I see imagery. I do not mean pictures; more usually they are patterns or textures, such as repeated shapes, or shadows of shapes, or an item from an image, such as grass from a landscape or wood grain, wavelets or raindrops … transformed in the most extraordinary ways at a great speed. Shapes are replicated, multiplied, reversed in negative, etc. Color is added, tinted, subtracted. Textures are the most fascinating; grass becomes fur becomes hair follicles becomes waving, dancing lines of light, and a hundred other variations and all the subtle gradients between them that my words are too coarse to describe.

PTSD seems to have an even higher prevalence and greater severity following violence or disaster that is man-made; natural disasters, "acts of God," seem somehow easier to accept. (...). This is the case with acute stress reactions, too: I see it often with my patients in hospital, who can show extraordinary courage and calmness in facing the most dreadful diseases but fly into a rage if a nurse is late with a bedpan or a medication. The amorality of nature is accepted, whether it takes the form of a monsoon, an elephant in musth, or a disease; but being subjected helplessly to the will of others is not, for human behavior always carries (or is felt to carry) a moral charge.

Our normal waking consciousness, rational consciousness, as we call it, is but one special type of consciousness, whilst all about it, parted from it by the filmiest of screens, there lie potential forms of consciousness entirely different.… Looking back on my own experiences, they all converge towards a kind of insight to which I cannot help ascribing some mystical significance. The keynote of it is invariably a reconciliation. It is as if the opposites of the world, whose contradictoriness and conflict make all our difficulties and troubles, were melted into unity.… To me [this sense] only comes in the artificial mystic state of mind.

The amorality of nature is accepted, whether it takes the form of a monsoon, an elephant in musth, or a disease; but being subjected helplessly to the will of others is not, for human behavior always carries (or is felt to carry) a moral charge.

When traditional figures—devils, witches, or hags—are no longer believed in, new ones—aliens, visitations from “a previous life”—take their place. Hallucinations,

Professional musicians, in general, possess what most of us would regard as remarkable powers of musical imagery. Many composers, indeed, do not compose initially or entirely at an instrument but in their minds. There is no more extraordinary example of this than Beethoven, who continued to compose (and whose compositions rose to greater and greater heights) years after he had become totally deaf. It is possible that his musical imagery was even intensified by deafness, for with the removal of normal auditory input, the auditory cortex may become hypersensitive, with heightened powers of musical imagery (and sometimes even auditory hallucinations).

I went back into the house and had put on the kettle for another cup of tea when my attention was caught by a spider on the kitchen wall. As I drew nearer to look at it, the spider called out, “Hello!” It did not seem at all strange to me that a spider should say hello (any more than it seemed strange to Alice when the White Rabbit spoke). I said, “Hello, yourself,” and with this we started a conversation, mostly on rather technical matters of analytic philosophy. Perhaps this direction was suggested by the spider’s opening comment: did I think that Bertrand Russell had exploded Frege’s paradox? Or perhaps it was its voice—pointed, incisive, and just like Russell’s voice (which I had heard on the radio, but also—hilariously—as it had been parodied in Beyond the Fringe).9 D

To restore the human subject at the center—the suffering, afflicted, fighting human subject—we must deepen a case history to a narrative or tale; only then do we have a “who” as well as a “what,” a real person, a patient, in relation to disease—in relation to the physical. The patient’s essential being is very relevant in the higher reaches of neurology, and in psychology; for here the patient’s personhood is essentially involved, and the study of disease and of identity cannot be disjoined.

I have discussed neurological aspects of time and motion perception, as well as cinematic vision, at greater length in two articles, “Speed” and “In the River of Consciousness.

Embodiment seems to be the surest thing in the world, the one irrefutable fact

The “mare” in “nightmare” originally referred to a demonic woman who suffocated sleepers by lying on their chests (she was called “Old Hag” in Newfoundland).

We now know that memories are not fixed or frozen, like Proust's jars of preserves n a larder, but transformed, disassembled, reassembled, and recategorised with every act of recollection. ~Hallucinations, Oliver Sacks

The amorality of nature is accepted whether it takes the form of a monsoon, an elephant is musth, or a disease; but being subjected helplessly to the will of others is not, for human behaviour always carries (or is felt to carry) a moral charge.

According to chaos theory, although it is impossible to predict the individual behavior of each element in a complex dynamic system (for instance, the individual neurons or neuronal groups in the primary visual cortex), patterns can be discerned at a higher level by using mathematical models and computer analyses. There are “universal behaviors” which represent the ways such dynamic, nonlinear systems self-organize. These tend to take the form of complex reiterative patterns in space and time—indeed the very sorts of networks, whorls, spirals, and webs that one sees in the geometrical hallucinations of migraine. Such chaotic, self-organizing behaviors have now been recognized in a vast range of natural systems, from the eccentric motions of Pluto to the striking patterns that appear in the course of certain chemical reactions to the multiplication of slime molds or the vagaries of weather. With this, a hitherto insignificant or unregarded phenomenon like the geometrical patterns of migraine aura suddenly assumes a new importance. It shows us, in the form of a hallucinatory display, not only an elemental activity of the cerebral cortex but an entire self-organizing system, a universal behavior, at work.*3

I had long wanted to see “true” indigo, and thought that drugs might be the way to do this. So one sunny Saturday in 1964, I developed a pharmacologic launchpad consisting of a base of amphetamine (for general arousal), LSD (for hallucinogenic intensity), and a touch of cannabis (for a little added delirium). About twenty minutes after taking this, I faced a white wall and exclaimed, “I want to see indigo now—now!” And then, as if thrown by a giant paintbrush, there appeared a huge, trembling, pear-shaped blob of the purest indigo. Luminous, numinous, it filled me with rapture: It was the color of heaven, the color, I thought, which Giotto had spent a lifetime trying to get but never achieved—never achieved, perhaps, because the color of heaven is not to be seen on earth. But it had existed once, I thought—it was the color of the Paleozoic sea, the color the ocean used to be. I leaned toward it in a sort of ecstasy. And then it suddenly disappeared, leaving me with an overwhelming sense of loss and sadness that it had been snatched away. But I consoled myself: Yes, indigo exists, and it can be conjured up in the brain. For months afterward, I searched for indigo. I turned over little stones and rocks near my house, looking for it. I examined specimens of azurite in the natural history museum—but even they were infinitely far from the color I had seen. And then, in 1965, when I had moved to New York, I went to a concert in the Egyptology gallery of the Metropolitan Museum of Art. In the first half, a Monteverdi piece was performed, and I was utterly transported. I had taken no drugs, but I felt a glorious river of music, four hundred years long, flowing from Monteverdi’s mind into my own. In this ecstatic mood, I wandered out during the intermission and looked at the ancient Egyptian objects on display—lapis lazuli amulets, jewelry, and so forth—and I was enchanted to see glints of indigo. I thought: Thank God, it really exists! During the second half of the concert, I got a bit bored and restless, but I consoled myself, knowing that I could go out and take a “sip” of indigo afterward. It would be there, waiting for me. But when I went out to look at the gallery after the concert was finished, I could see only blue and purple and mauve and puce—no indigo. That was nearly fifty years ago, and I have never seen indigo again.

If one loses half the visual field from a stroke or other injury, one may or may not be aware of the loss. Monroe Cole, a neurologist, became aware of his own field loss only by doing a neurological exam on himself after his coronary bypass surgery. He was so surprised by his lack of awareness of this deficit that he published a paper about it. “Even intelligent patients,” he wrote, “often are surprised when a hemianopia is demonstrated, despite the fact that it has been demonstrated on numerous examinations.

There are similar irrefutable beliefs in patients who lose the perception of their left side and the left side of space but maintain that there is nothing missing, even though we can demonstrate convincingly that they live in a hemi-universe. Such syndromes—so-called anosognosias—occur only with damage to the right half of the brain, which seems to be especially concerned with the sense of bodily identity.

Adler studied a group of Hmong refugees from Laos who had immigrated to central California in the late 1970s and were not always able to perform their traditional religious rites during the upheaval of genocide and relocation. In Hmong culture, there is a strong belief that night-mares can be fatal; this evil expectation, or nocebo, apparently contributed to the sudden unexplained nocturnal deaths of almost two hundred Hmong immigrants (mostly young and in good health) in the late 1970s and early 1980s. Once they were more assimilated and the old beliefs lost their power, the sudden deaths stopped.

And at this point, self-stimulation of various sorts began: mental games, counting, fantasies, and, sooner or later, visual hallucinations—usually a “march” of hallucinations from simple

William James, in his lectures on exceptional mental states, referred to the trances of mediums who channel voices and images of the dead, and of scryers who see visions of the future in a crystal ball. Wheather the voices and visions in these contexts were veridical was less of a concern to James than the mental states which could produce them. Careful observation convinced him that mediums and crystal gazers were not usually conscious charlatans or liars in the ordinary sense, nor were they confabulators or phantasm. They were, he came to feel, in altered states of consciousness conducive to hallucinations - hallucinations whose content was shaped by the questions they were asked. These exceptional mental states, he thought, were achieved by self-hypnosis, no doubt facilitated by poorly lit and ambiguous surroundings and the eager expectations of their clients.

Studies by Andrew Newberg and others have shown that long-term practice of meditation produces significant alterations in cerebral blood flow in parts of the brain related to attention, emotion, and some autonomic functions. T

(Hallucination of particularly vile smells is called cacosmia.)

All the colours I have ever beheld are dull as compared to these.

Spontaneous self-organization is not restricted to living systems;

All of a sudden, out of a clear blue sky, the Charles Bonnet has come back with a vengeance.

Such epileptic hallucinations or dreams, Penfield showed, are never phantasies: they are always memories, and memories of the most precise and vivid kind, accompanied by the emotions which accompanied the original experience. Their extraordinary and consistent detail, which was evoked each time the cortex was stimulated, and exceeded anything which could be recalled by ordinary memory, suggested to Penfield that the brain retained an almost perfect record of every lifetime’s experience, that the total stream of consciousness was preserved in the brain, and, as such, could always be evoked or called forth, whether by the ordinary needs and circumstances of life, or by the extraordinary circumstances of an epileptic or electrical stimulation.

But the feeling of a limb as a sensory and motor part of oneself seems to be innate, built-in, hardwired—and this supposition is supported by the fact that people born without limbs may nonetheless have vivid phantoms in their place.4

The best way of doing this, I found, was to write, to describe the hallucination in clear, almost clinical detail, and, in so doing, become an observer, even an explorer, not a helpless victim of the craziness inside me.

After a while the scene started to fade, and I became dimly conscious, once more, that I was in London, stoned, hallucinating Agincourt on the sleeve of my dressing gown. It

The situation changed for Michael and for millions of other schizophrenics, for better and worse, around 1953, when the first tranquilizer—a drug called Largactil in England, Thorazine in the United States—became available. The tranquilizers could damp down and perhaps prevent the hallucinations and delusions, the “positive symptoms” of schizophrenia, but this could come at great cost to the individual.

In REM sleep the body is paralyzed, except for shallow breathing and eye movements.

the delirious visions when they came to him may have owed something to opium as well as to a high temperature, since opium was then a normal remedy for ague or malaria.

Interchanges between the senses are frequent and astonishing: One knows the smell of a low B flat, the sound of green, the taste of the categorical imperative (which is something like veal).” No

A smudge on the wall is an object of limitless fascination, multiplying in size, complexity, color. But more than that, one sees every relationship it has to the rest of the universe; it possesses, therefore, an endless variety of meanings, and one proceeds to entertain every possible thought there is to think about it. And

Patients with delirium were almost always on medical or surgical wards, not on neurological or psychiatric wards, for delirium generally indicates a medical problem, a consequence of something affecting the whole body, including the brain, and it disappears as soon as the medical problem has been righted.

The amorality of nature is accepted, whether it takes the form of a monsoon, an elephant in musth, or a disease; but being subjected helplessy to the will of of others is not, for human behavior always carries (or is felt to carry) a moral charge

Si un hombre ha perdido una pierna o un ojo, sabe que ha perdido una pierna o un ojo; pero si ha perdido el yo, si se ha perdido a sí mismo, no puede saberlo, porque no está ahí ya para saberlo.

To restore the human subject at the centre--the suffering, afflicted, fighting, human subject--we must deepen a case history to a narrative or tale; only then do we have a 'who' as well as a 'what', a real person, a patient, in relation to disease--in relation to the physical.

There was general astonishment, therefore, when Matthew Botvinick and Jonathan Cohen showed in 1998 that a rubber hand, under the right circumstances, could be mistaken for one’s own. If a subject’s real hand is hidden under a table while the rubber hand is visible before him, and both are stroked in synchrony, then the subject has the convincing illusion, even though he knows better, that the rubber hand is his—and that the sensation of being stroked is located in this inanimate though lifelike object. As I found when I looked through the “eyes” of a robot, knowledge in such a situation does nothing to dispel the illusion. The brain does its best to correlate all the senses, but the visual input here trumps the tactile.

... that I feel myself a naturalist and a physician both; and that I am equally interested in diseases and people; perhaps, too, that I am equally drawn to the scientific and romantic, and continually see both in the human condition, not least in that quintessential human condition of sickness- animals get diseases, but only man falls radically into sickness.

Humans share much with other animals — the basic needs of food and drink or sleep, for example — but there are additional mental and emotional needs and desires which are perhaps unique to us. To live on a day-to-day basis is insufficient for human beings; we need to transcend, transport, escape; we need meaning, understanding, and explanation; we need to see overall patterns in our lives. We need hope, the sense of a future. And we need freedom (or at least the illusion of freedom) to get beyond ourselves, whether with telescopes and microscopes and our ever-burgeoning technology or in states of mind which allow us to travel to other worlds, to transcend our immediate surroundings. We need detachment of this sort as much as we need engagement in our lives… transports that make our consciousness of time and mortality easier to bear. We seek a holiday from our inner and outer restrictions, a more intense sense of the here and now, the beauty and value of the world we live in.

...a disease is never a mere loss or excess— that there is always a reaction, on the part of the affected organism or individual, to restore, to replace, to compensate for and to preserve its identity, however strange the means may be: and to study or influence these means, no less than the primary insult to the nervous system, is an essential part of our role as physicians.

Thus the primal, animal sense of 'the other,' which may have evolved for the detection of threat, can take on a lofty, even transcendent function in human beings, as a biological basis for religious passion and conviction, where the 'other,' the 'presence,' becomes the person of God.

Gertie C. had had a half-controlled hallucinosis for decades before she started on L-dopa - bucolic hallucinations of lying in a sunlit meadow or floating in a creek near her childhood home. This changed when she was given L-dopa, and her hallucinations assumed a social and sometimes sexual character. When she told me about this, she added, anxiously - You surely wouldn’t forbid a friendly hallucination to a frustrated old lady like me! I replied that if her hallucinations had a pleasant and controllable character, they seemed rather a good idea under the circumstances. After this, the paranoid quality dropped away, and her hallucinatory encounters became purely amicable and amorous. She developed a humor and tact and control, never allowing herself a hallucination before eight in the evening and keeping its duration to thirty to forty minutes at most. If her relatives stayed too late, she would explain firmly but pleasantly that she was expecting a gentleman visitor from out of town in a few minutes’ time, and she felt he might take it amiss if he was kept waiting outside. She now receives love, attention, and invisible presents from a hallucinatory gentleman who visits faithfully each evening.

A clear distinction between normal visual imagination and actual hallucination: imagining a colored object did not activate V4 area while a colored hallucination did.

not so long ago, all humans heard voices—generated internally, from the right hemisphere of the brain, but perceived (by the left hemisphere) as if external, and taken as direct communications from the gods. Sometime around 1000 B.C., Jaynes proposed, with the rise of modern consciousness, the voices became internalized and recognized as our own.21

Many cultures regard hallucination, like dreams, as a special, privileged state of consciousness—one that is actively sought through spiritual practices, meditation, drugs, or solitude. But in modern Western culture, hallucinations are more often considered to portend madness or something dire happening to the brain—even though the vast majority of hallucinations have no such dark implications.
