Advertising in Dreams is Coming: Now What?

Molson Coors recently announced a new kind of advertising campaign. Timed for the days before Super Bowl Sunday, it was designed to infiltrate our dreams [1]. They planned to use "targeted dream incubation" (TDI) [2] to alter the dreams of the nearly 100 million Super Bowl viewers the night before the game—specifically, to have them dream about Coors beer in a clean, refreshing, mountain environment—and presumably then drink their beer while watching the Super Bowl. Participants in what Coors called ‘the world’s largest dream study’ would get half off on a 12 pack of Coors; if they sent the link to a friend who also incubated their dreams, the 12 pack was free. With this campaign, Coors is proudly pioneering a new form of intrusive marketing. “Targeted Dream Incubation (TDI) is a never-before-seen form of advertising,” says Marcelo Pascoa, Vice President of Marketing at Molson Coors [3]. 

With brain imaging techniques beginning to capture the core contents of people’s dreams [4] and sleep studies establishing real-time communication between researchers and sleeping dreamers [5], the kind of dream incubation until recently assumed to be the pure science fiction of movies like Inception is now becoming reality. Coors is not the only company expressing interest in using these novel dream incubation technologies: Xbox's Made From Dreams uses TDI to give professional gamers dreams of their favorite video games, while Playstation advertises a new Tetris game based on a sleep study demonstrating that gameplay incubates Tetris dreams [5]. In 2018, Burger King created a "nightmare" burger for Halloween, claiming that a sleep laboratory study had ‘clinically proven’ it would induce nightmares [6]. And multiple marketing studies are openly testing new ways to alter and motivate purchasing behavior through dream and sleep hacking [7, 8]. The commercial, for-profit use of dream incubation is rapidly becoming a reality. 

Traditions of dream incubation—techniques employed during wakefulness to help a person dream about a specific topic—go back thousands of years and span indigenous practices across the globe. Over the last few years, brain scientists have begun to develop scientific tools that facilitate this incubation of specific dream content [2], making dream incubation more targeted and measurable, and allowing scientific experimentation on the nature and function of dreaming. They use sensors to determine when an individual’s sleeping brain is receptive to external stimuli and, at these times, introduce smells, sounds, flashing lights or even speech to influence the content of our dreams [9]. 

Dreams have ties to people’s well-being [10, 11], and dream content can predict how well someone will adapt to waking challenges and concerns, including those related to trauma and depression [12, 13]. Altering dream content can augment our creativity, boost our mood, and help us learn [14, 15]. We believe that targeted intervention in sleep and dreams could help alleviate several psychiatric conditions including depression and PTSD [12]. We know that targeted delivery of odors during sleep can help combat addiction; participants exposed during their sleep to the smells of cigarettes along with those of rotten eggs smoked 30% fewer cigarettes over the following week [16]. Researchers have not yet tested whether TDI can instead worsen addiction, but the Coors study, which paired images of beer cans not with odious smells but with images of clean mountain streams, may shine a disturbing light on this question. Regardless, such interventions clearly influence the choices our sleeping and dreaming brain make in how to interpret the events from our day, and how to use memories of these events in planning our future, biasing the brain's decisions toward whatever information was presented during sleep [17, 18].

These questions and developments should be considered in the broader context of sleep and memory research. The last twenty years have been a watershed for sleep research during which we have come to understand the importance of sleep for our memories and emotional health. It is while we sleep that our brain decides which memories to keep and which to forget, and how to organize those it keeps [19, 20]. It also can choose to keep the gist or the emotional core of a memory while letting other details be forgotten [20, 21]. Through this nocturnal process, the brain shapes the memories that together create our autobiographical past, our sense of who we are now, and our understanding of how best to live our lives in the future.

More recent studies have shown that dreaming represents another aspect of this nightly memory evolution. Our dreams are not attempts to suppress undesirable wishes, nor are they simply the result of random brain activity during sleep. Dreaming represents an evolved mechanism for exploring the relevance and importance of older memories to newer ones, seeking to position the events of our day among the innumerable memories and concepts we have accumulated across a lifetime [18], helping to make us just a bit wiser in the process. 

For now, TDI-based advertising requires our active participation, for example choosing to play an 8-hour Coors soundtrack while we sleep. But it is easy to envision a world in which smart speakers—40 million Americans currently have them in their bedrooms [22]— become instruments of passive, unconscious overnight advertising, with or without our permission. These tailored soundtracks would become background scenery for our sleep, as the unending billboards that litter American highways have become for our waking life. 

Our dreams cannot become just another playground for corporate advertisers. Regardless of Coors’ intent, their actions set the stage for a corporate assault of our very sense of who we are. And it is not difficult to imagine Coors' ad campaign negatively impacting abstinent alcoholics. Indeed, research has shown that abstinent drug users who report dreaming about their drug-use show higher levels of craving [23]. In the cigarette cessation study mentioned above, not only was the intervention effective in sleep (yet ineffective when the smells were presented during wake), but participants reported no memory of being exposed to these smells in the morning. The potential for misuse of these technologies is as ominous as it is obvious. 

TDI-advertising is not some fun gimmick, but a slippery slope with real consequences. Planting dreams in people’s minds for the purpose of selling products, not to mention addictive substances, raises important ethical questions. The moral line dividing companies selling relaxing rain soundtracks to help people sleep from those embedding targeted dreams to influence consumer behavior is admittedly unclear at the moment. While the Federal Trade Commission has indicated that subliminal ads during wake violate its statute requiring truth in advertising, there is no similar indication regarding exposure to advertisements during sleep. 

As sleep and dream researchers, we are deeply concerned about marketing plans aimed at generating profits at the cost of interfering with our natural nocturnal memory processing. Brain science helped design several addictive technologies, from cell phones to social media, that now shape much of our waking lives; we do not want to see the same happen to our sleep. We believe that proactive action and new protective policies are urgently needed to keep advertisers from manipulating one of the last refuges of our already beleaguered conscious and unconscious minds: Our dreams.

Tips for Good Writing

Third Millennium Narcissus (Francesco Galgani's art, December 21, 2021)
(Third Millennium Narcissus, December 21, 2021, go to the art gallery)

Words create reality, so good writing creates good reality.

The writing I'm referring to here is "exploratory": the human being is a wanderer, an explorer, a being who moves forward by trial and error. There are no "experts" in anything because every path of knowledge requires doubt and error. Intuition does not follow logical paths, as it arrives directly at its destination. Emotions and feelings push us in different directions; they make us fall, they make us stand up, they make us act. The human mind is the place of chaos, like a small universe that reflects the big universe: mind and universe are in the same way, or maybe they are the same thing.

We are a mystery and, above all, a plurality: there is no "single human being," there is no "person." There is no individuality detached from everything else.

Starting from these assumptions, I try to imagine some tips for good writing. I mean a writing habit that can help us answer two questions: "who we are?" and "how to live together?".

An old saying goes: «Three things we should ask ourselves before speaking. The first: "Are these words true?". The second: "Are they necessary?". The third: "Are they kind?". If they are true, necessary, and kind, they deserve to be spoken.». This saying is probably a short form of the Socrates' Triple Filter Test.

1. Reality or inclusiveness?

"Yesterday I saw a terrible scene: a big wolf-dog - but maybe it was a wolf - trying to bite a little girl. This one didn't dare to run away because she knew that the animal was much faster than her. To defend herself, she first gave it a sort of blanket, already in tatters, to bite on. Then, seeing that the wolf did not give up, she tried to distract it by throwing away the ball it was playing with: this happened two or three times. Finally, the little girl, terrified, while the other one was attacking the ball, hid behind a tree, but in vain... I don't know how it ended because I ran away to get help".

Or:

"Yesterday, I saw a delightful scene: a little girl playing with a wolf-dog that was bigger than her. They were trying to tear a tattered old blanket from each other, but I could see that the dog was pulling slowly so the little girl wouldn't fall. Then she started throwing a ball at it, and it would run to catch it: this happened two or three times until the little girl hid behind a tree, and the dog pretended for a while not to see her... At a certain distance, there was another child who wanted to play too, but someone must have called him back because at a certain point he ran away".

It's the same story, from two perspectives that are both legitimate.

Does "reality" exist, or are there as many realities as possible observers and points of view?

Wanting to affirm a particular reality while firmly denying all others is divisive. Division gives birth to fears, anxieties, weakness, arrogance, violence, disease. The division makes us stupid, and the union makes us smarter. The more we divide, the worse we live. It's like a group of friends making music together. Not even one concert would succeed if each musician played without considering all the others (and possible mutual mistakes).

Everything works well when we seek harmony, not a war to distinguish us from each other.

2. Necessity or creativity?

We human beings are creative and social. We need to dialogue to explore new paths and understand ourselves, and, above all, because we strongly need other human beings. Dialogue is not just an exchange of information: it is a mutual growth path. Writing is, first of all, a dialogue with oneself and, only afterward, with those who will read. In this way, we can also dialogue with people far away in time and space.

From this point of view, all motivations for starting a dialogue can be good, except two: "trying to convince someone of something" and "imposing one's will." In other words: persuasive communication is the only kind of communication that, instead of advancing us in awareness, blocks the human evolution of both the speaker and the listener. The disasters and falsehoods of advertising and political communication are examples of this.

Persuasive, self-centered communication is that one of wars and death.
Exploratory and open to one's mistakes communication is that one of life.

Just a reminder: Narcissus killed himself because he could only look at himself.

3. Kindness or empathy?

Can a termination letter be kind?
Can words of contempt for the choices and emotions of others be kind?
Is politically correct (but ethically corrupt) language kind?

Perhaps, more than choosing our words well, we should also put ourselves in others' shoes, not just our own. Performing a miracle is not about transforming the world but changing perspective.

Child regressions in an unmanageable reality

Reality is dual and carries contradictory facts, news, feelings, opinions, and beliefs. Opposites coexist. Usually, we can manage the conflicting nature of existence simply by focusing ourselves, that is, by creating a personal reality in which everything is coherent: as long as basic needs are satisfied (money, social recognition, love and friendships, health and sex, sports and other interests, etc.) this trick can work. This precarious attitude does not require great responsibility: we can divide things into "white" and "black," "right" and "wrong," "true" and "false," and spend an entire life in ignorance but satisfied. This comfortable view of reality forces us to make enemies: the existence of the enemy, who is always in error, justifies our way of life, which will therefore be, more or less, always correct.

However, the current social context makes this fake comforting living increasingly tricky. In general: money is lacking; social recognition implies complete masochistic prostitution to the dictatorship of the moment; love is more precarious than a job; friendships in social networks are often fake; health has given way to the fear of death and the near-certainty of not receiving help in case of need; etc.

These challenges do not affect all people; however, there is a substantial existential discomfort for the majority, partly because people lack reference points.

The information that comes through TV and social media is, on the whole, completely unreliable: it is contradictory and often based on a faithful adherence to an ideology. The words of the politicians in charge and their helpers are mandates; their words are truths lowered from overhead that are contradictory because politicians deny themselves without a moment of remorse or admission of guilt.

We live in "cognitive dissonance," a state of confusion of the human mind that leads the individual and the masses to regress to previous stages of the evolution of the reason, which is the child one.

In other words, when we live in a situation that rationally is not sustainable and without a solution because of hopeless conflict, our mind regresses to a child state. We ideally put ourselves in the hands of parental authority, which will solve the problem. Symbolically, we give this parental authority to those who govern us because reality has lost all sense, and therefore we have no choice but to rely on someone.

We can choose who we prostitute ourselves to; for example, some suitable authorities might be: the prime minister of the moment, any religious leader, the head of some cult, an angel, a demon, a lover, an alien, the office manager, our executioner, etc. Anyway, we sell our souls, replacing our conscience with someone else's.

From this point of view, asking God for help is just as childish and dangerous as asking Satan for help.

The alternative is to reject all faiths except faith in ourselves. This choice is the most challenging since it requires a lot of awareness and, in any case, it can lead to martyrdom, abandonment, social exclusion, loss. However, the similar attracts the similar, so, in reality, we are never alone.
