Jung's theory of neurosis
"Although adjusted well enough to everyday life, the individual has lost a fulfilling sense of meaning and purpose, and has no living religious belief to which to turn. There seems to be no readily apparent way to set matters right. In these cases, Jung turned to ongoing symbolic communication from the unconscious in the form of dreams and visions."

Mind-reading devices can now access your thoughts and dreams using AI | New Scientist, Sep 2018
"We can now decode dreams and recreate images of faces people have seen, and everyone from Facebook to Elon Musk wants a piece of this mind reading reality"

"From an fMRI brain scan, Liu’s AI can say which of a selection of 15 different things a person was viewing when the scan was taken. For example, if someone was looking at a picture of a face, the AI can detect patterns in their scan that convince it to say “face”. Other options include birds, aeroplanes and people exercising, and the AI can call the correct category 50 per cent of the time."

Jack Gallant, UC Berkely: "When shown brain scans of someone watching a different YouTube video, the AI was able to generate a new movie of what it thought the person was viewing. The results are eerie outlines of the original, but still recognisable."

"Yukiyasu Kamitani at Japan’s Advanced Telecommunications Research Institute first showed in 2013 that it is possible to train an AI to detect the content of someone’s dreams, describing each in basic terms such as whether there was a male or female character, the objects included and details about the overall scene. Kamitani’s system has an accuracy of about 60 per cent."

"However, one big drawback of EEG is that there is so much unwanted noise to contend with. "

"The progress using AI with fMRI is causing people to rethink what EEG might be capable of."

We've started to uncover the true purpose of dreams | New Scientist, Jul 2018
"Mark Blagrove at Swansea University in the UK and his colleagues have found that the emotional strength of the experiences we have when we are awake is linked to the content of our dreams, and the intensity of our dreaming brainwaves."

"Together, these findings suggest that the most intense dreaming activity occurs when our brains are working hard to process recent, emotionally powerful experiences."

Dream on: My year pursuing the third state of being | New Scientist, Dec 2018
"Dreaming represents a state in between consciousness and unconsciousness, and this year I’ve been trying to get on top of what we know about this universal and mysterious experience. I went to a dream conference in Arizona, and spent the night in a dream lab in Swansea, UK. There I learned about research providing evidence, for the first time, that explains the purpose of dreaming.

But while scientists are learning more about the function of dreams and of sleep, I’ve been particularly drawn to the mysterious border state between wakefulness and slumber. Sleep scientists call this transient period the hypnagogic state, a highly creative state that has been actively pursued by artists and scientists over the years."

The brain’s default mode network – what does it mean to us? Mar 2015
Marcus Raichle interviewed by Svend Davanger

"The default mode network is comprised of several areas of the cortex that are most active when no external tasks demand our attention"

"It was really surprising that, after the demanding tasks were completed, activity in these areas of the cortex increased again. The brain seemed to revert back to a default activity level, which is there in the absence of a specific, ongoing, external task"

"Many of the functions of the network are associated with our perception of our selves."

"It’s not only important to remember what’s important, but also to put a value on what’s important. The part of the default mode network up front, down almost between your eyes, just above your nose, has to do with deciding whether something is good, bad, or indifferent."

"Dreaming is mind-wandering disconnected. Why do we dream? Although there is no clear scientific answer, we cannot claim that dreams are just an inconvenience."

“To summarize the function of the three networks: the attention network makes it possible for us to relate directly to the world around us, i.e., here and now, and the default mode network makes it possible to relate to ourselves and our memories and previous experiences, i.e., the past and future. The salience network makes us switch between the two others according to our needs.”

Dreaming and the Default Mode Network: Some Psychoanalytic Notes: Contemporary Psychoanalysis: Vol 49, No 2

This article makes a brief contribution to the ongoing dialogue on dreams between neuroscience and psychoanalysis by linking several converging lines of evidence. Recent evidence indicates that the default mode network (DMN), a highly interconnected set of “hubs” in the brain, is active during sleep. In addition, activity in the DMN is strongly associated with mental imagery that is not directly tied to current perception (“stimulus-independent thought”), which is also a central feature of dreams. Finally, the elimination of dreams is correlated with lesions in areas that have a high degree of overlap with two regions of the DMN, the ventromedial prefrontal cortex (vmPFC) and the temporo-occipital junction. Given that the vmPFC is a key node in brain circuitry regulating motivation, these converging lines of evidence support the basic psychoanalytic idea that dreams arise from wishful impulses and other emotional motivations.

Sleep and dreaming: Where do our minds go at night? | New Scientist Jan 2013
"dreams tend to be silent movies – with just half containing traces of sounds. It is even more unusual to enjoy a meal or feel damp grass beneath your feet – taste, smell and touch appearing only very rarely. Similar studies have tried to pin down some of the factors that might influence what we dream about, though they have struggled to find anything reliable."

"the idea that sleep helps to cement our memories for future recall "

[Mark Blagrove at Swansea University]'s "team has found that memories enter our dreams in two separate stages. They first float into our consciousness on the night after the event itself, which might reflect the initial recording of the memory, and then they reappear between five and seven days later, which may be a sign of consolidation"

"the sleeping brain also forges links to other parts of your mental autobiography, allowing you to see associations between different events"

"Perhaps the intense images are an indication of what a difficult process it is integrating a traumatic event with the rest of our autobiography."

"Despite these advances, many, many mysteries remain. Top of the list is the question of the purpose of our dreams: are they essential for preservation of our memories, for instance – or could we manage to store our life’s events without them? “There’s no consensus,” says [Patrick McNamara at Northcentral University]."

"some research suggesting that TV may have caused a major shift in the form and content of our dreams"

Weird dream? Your brain won't even try to make sense of it | New Scientist, Apr 2015
"The bizarre can seem completely normal when you’re dreaming, perhaps because parts of your brain give up trying to figure out what’s going on. Armando D’Agostino of the University of Milan in Italy thinks that the strangeness of dreams resembles psychosis, because individuals are disconnected from reality and have disrupted thought processes that lead to wrong conclusions."

"Using a “bizarreness” scoring system, the researchers found that dreams were significantly weirder than the waking fantasies the volunteers composed. "

Houses: Drawings by Stefan Zsaitsits
Austria-based artist Stefan Zsaitsits has shifted his focus from the drawings of childlike figures in which he hybridizes particular thoughts and emotions to surreal houses that play on you psychologically. Each house seems to represent his unfiltered stream of thoughts and memories forming a new delusion that adds a sense of mystery to the drawings and makes you think that there is something more beyond the physical structure of the home.

We dream loads more than we thought – and forget most of it | New Scientist Issue 3121, 15 Apr 2017
"Francesca Siclari at the University of Wisconsin-Madison and her colleagues have discovered that a decrease in these waves in an area at the back of the brain is a sign that someone is dreaming."

"The team found such a strong correlation between dreaming and fewer low-frequency waves in the “hot zone” that they could successfully predict whether a person was dreaming 91 per cent of the time."

"Monitoring seven people over five to 10 nights of sleep, Siclari found the volunteers dreamed during 71 per cent of their non-REM sleep, in addition to 95 per cent of their REM sleep. Despite all this dreaming, many dreams are forgotten. Sometimes participants had a foggy idea they had been dreaming, but couldn’t remember what about. In a further experiment with 10 people, the team found that being able to later remember a dream was linked to higher activity in the prefrontal cortex – which is associated with memory – while dreaming. "

Siclari et al, The neural correlates of dreaming
Nat Neurosci. 2017 Jun;20(6):872-878. doi: 10.1038/nn.4545. Epub 2017 Apr 10.
Consciousness never fades during waking. However, when awakened from sleep, we sometimes recall dreams and sometimes recall no experiences. Traditionally, dreaming has been identified with rapid eye-movement (REM) sleep, characterized by wake-like, globally 'activated', high-frequency electroencephalographic activity. However, dreaming also occurs in non-REM (NREM) sleep, characterized by prominent low-frequency activity. This challenges our understanding of the neural correlates of conscious experiences in sleep. Using high-density electroencephalography, we contrasted the presence and absence of dreaming in NREM and REM sleep. In both NREM and REM sleep, reports of dream experience were associated with local decreases in low-frequency activity in posterior cortical regions. High-frequency activity in these regions correlated with specific dream contents. Monitoring this posterior 'hot zone' in real time predicted whether an individual reported dreaming or the absence of dream experiences during NREM sleep, suggesting that it may constitute a core correlate of conscious experiences in sleep."

Jung on the Nature and Interpretation of Dreams: A Developmental Delineation with Cognitive Neuroscientific Responses - Zhu - Behavioral Sciences | Free Full-Text |
"Post-Jungians tend to identify Jung’s dream theory with the concept of compensation; they tend to believe that Jung’s radically open stand constitutes his dream theory in its entirety. However, Jung’s theory regarding dreams was a product of an evolving process throughout his whole intellectual and professional life. Unfortunately, the theory has not been understood in such a developmental light. Based on a historical and textual study of all dream articles found throughout The Collected Works of C.G. Jung, this paper maps a concise three-phase trajectory of Jung’s changing views on dreams and interpretation. The paper posits that Jung’s last essay, “Symbols and the Interpretation of Dreams” (1961), epitomizes his final stand, although such a stand is also reflected in a less explicit and less emphatic way during the latter period of the second phase. The paper also briefly addresses where Jung and Jungians have been enigmatic or negligent. For example, ..."
