Lucid dreaming — realising you are in a dream while dreaming — has these cognitive benefits.

People who realise they are in a dream while they are dreaming — a lucid dream — have better problem-solving abilities, research finds.

This may be because the ability to step outside a dream after noticing it doesn’t make sense reflects a higher level of insight.

Around 82 percent of people are thought to have experienced a lucid dream in their life, while the number experiencing a lucid dream at least once a month may be as high as 37 percent.

Lucid dreaming study

The study, published in the journal Dreaming, recruited participants into three groups (Bourke & Shaw, 2014):

• Frequent lucid dreamers: those who experienced a lucid dream more than once a month.
• Occasional lucid dreamers: those who had had a lucid dream at least once in their lives.
• Non-lucid dreamers: those who had never experienced a lucid dream.

All the participants were given a test of problem-solving which required a flash of insight.

Each problem was made up of three words which led to another word or phrase.

For example, one problem gives you the words ‘mile’, ‘sand’ and ‘age’.

What other single word can be combined with all three to create three new words or phrases?

Got it?

Give up?

The answer is ‘stone’, which can be combined with the three words to produce ‘milestone’, ‘sandstone’ and ‘Stone Age’.

Solving insight problems

The results showed that in comparison to those who had never had a lucid dream, the frequent lucid dreamers solved 25 percent more of these insight problems.

Dr Patrick Bourke, who led the study, said:

“It is believed that for dreamers to become lucid while asleep, they must see past the overwhelming reality of their dream state, and recognise that they are dreaming.

The same cognitive ability was found to be demonstrated while awake by a person’s ability to think in a different way when it comes to solving problems.”

Lucid dreaming and solving insight problems may tap into similar cognitive abilities, the authors suggest:

“‘Insight’ can be seen to be related to other demonstrated cognitive correlates of lucidity in dreaming.

The tendency towards ‘field independence’ for example allows people to ‘step back’ from perceived reality, reflect on it and evaluate the perceptual evidence.

For the insight that leads to lucidity, people also seem able to step-back from the obvious interpretation and consider a remote and at the time implausible option – that it is all a dream.” (Bourke & Shaw, 2014)

How to start lucid dreaming

If you’d like to increase the chances you’ll catch yourself dreaming while asleep, here are three tips:

• During the day, repeatedly ask yourself if you’re dreaming.
• When you’re asleep, try to identify any signs or events that would be weird in real life. As you know, dreams are usually chock full of them.
• Keep a dream journal to help you focus on your dreams. Write down whatever you can remember when you wake up.

Sweet dreams!

We all live two mental lives.

When we are awake it is mostly ordered, rational, linear and bounded by rules, both behavioural and physical.

But when we are asleep it is chaotic, non-linear, without rules, often without sense, which opens the way to dream interpretation.

According to some psychologists, dreams are nothing more than the by-product of a brain disconnected from its normal sensory inputs, free-wheeling its way through the night.

To others, dreams denote night-time learning or problem-solving, even automatic sifting of the mind’s detritus, the skimming off of useless information to be dumped like so much mental junk.

Amongst the general public, though, there are much stronger beliefs about the power of dreams — hence the popularity of dream interpretation.

So strong that, according to research, people seem to believe dreams can predict the future.

Freudian dream interpretation

To see how much meaning people ascribe to their dreams, Carey Morewedge and Michael Norton asked participants to compare four ways of thinking about dreams (Morewedge & Norton, 2009):

• Freudian: dream interpretation reveals buried truths about the self.
• Problem-solving: dreams help us work through our problems while we sleep.
• Learning theory: dreams are how we process and sort out the day’s events.
• Random: dreams are vivid hallucinations that result from our brains trying to interpret random impulses.

Notice the last three theories all share the idea that, while dreaming may or may not have a psychological purpose, the actual content of our dreams is still mental junk: sometimes entertaining, sometimes frightening, often weird, but with no real meaning in and of itself.

The content only has a strong meaning in the Freudian approach.

Participants from the United States, South Korea and India were all more likely to endorse the Freudian view of dream interpretation than the other three.

In the US sample it was 56 percent Freudian, 8 percent problem-solving, 18 percent random and 18 percent learning.

Dream interpretation of a plane crash

Although 56 percent endorsing Freud might sound high, Morewedge and Norton thought it was still an underestimate of how much store people put by their dreams.

So,a second and third study asked both Freudians and non-Freudians to estimate the effect of their dreams on behaviour.

Participants were asked to imagine they were taking a flight tomorrow when each of the following events happened the night before:

• They consciously thought about the plane crashing on the route they were going to take.
• They had a dream about the same thing.
• Or, it actually happened the night before!

They were then asked to put these in order of most to least likely to make them cancel their flight.

My money was in the same place as I’d guess yours is: on the real plane crash being the most off-putting.

For the Freudians in the group, though, we’d both be wrong.

Incredibly, they thought the dream would be the greatest motivator to cancel the flight, even more so than an actual, real-life crash.

Non-Freudians rated the real-world event as more influential than the dream, but only just.

Giving the lie to their non-Freudian stance, though, they still thought dream interpretation would be more influential than thoughts they had while they were awake.

So the majority of people think their dreams will influence their waking life, often more so than a similar waking thought.

But the experimenters wanted to push it further: what if a dream’s message conflicted with a person’s best interests?

Dream cheats

Morewedge and Norton’s next two experiments used a common dream in which someone we like does something nasty to us.

In this case it was dreaming that a friend had betrayed us by kissing our partner.

What they found was that people who remembered a dream about their friend kissing their partner tended to think it was meaningless, but when the dream cheat was someone they didn’t like, it was filled with meaning.

This suggests people only imply meaning into their dreams when the implications fit their motives.

In a final study experimenters pitted people’s dreams up against their religious beliefs.

Again, participants demonstrated a motivational interpretation of their dreams.

They were happy to endorse the meaningfulness of their dreams, unless it contradicted their religious beliefs, in which case they deemed them meaningless.

Dangers of dream interpretation

Dream interpretation is not always a purely innocent pastime.

Dream interpretation can even implant false memories in people’s minds, either accidentally or when carried out in a malicious way.

An experiment by Giuliana Mazzoni from the University of Florence and colleagues demonstrates the power psychotherapists potentially wield with a mere 30 minute interpretation of a dream (Mazzoni et al., 1999).

This intriguing experiment had three stages:

1. Participants’ very early childhood memories were tested.
2. Dream interpretation was used to implant a false childhood event that was mildly traumatic.
3. Participants’ memories were tested again for their belief in the implanted event and whether they had constructed any memories associated with it.

This is how it worked:

Part 1: Early childhood memories

One-hundred and fifty-nine potential participants were first asked to fill out a questionnaire asking about events they remembered occurring to them before the age of 3.

The questionnaire asked how confident they were in each of these memories.

The events included things like ‘found some lost keys’ or ‘hand caught in mousetrap’, but there were two questions experimenters were particularly interested in: ‘was harassed by a bully’ and ‘was lost in a public place for more than one hour’.

Only the 72 who were reasonably confident this event hadn’t happened to them were selected for the experiment.

These participants were then randomly split into two groups, with one acting as a control group while the other group were targeted with a dream interpretation session designed to change their beliefs and memories.

Part 2: Dream interpretation

Around two weeks, later the dream interpretation group were invited to take part in another study which appeared unrelated to the earlier questionnaire they had filled out.

They were told it was a ‘Dream and Cognition Study’, where they would bring two of their dreams to a session with an expert in dream interpretation.

In fact the expert dream interpreters were the experimenters.

When participants arrived at the session they were introduced to a ‘clinical psychologist’ who would interpret their dreams.

But the clinical psychologist, over a 30 minute session, instead of interpreting all the different dreams brought to her in different ways, rather single-mindedly gave one specific interpretation to all the different dreams.

Every participant was ultimately told that their dream probably indicated they had been bullied as a child or lost in a public space depending on which question they had answered ‘no’ to in the earlier questionnaire.

It was also suggested this had probably happened before the age of 3.

Participants in the control group did not take part in this section of the study.

Part 3: dream interpretation implanted false memories

A further couple of weeks later all the participants were called back to fill in exactly the same questionnaire they had completed in part 1.

They were told that this study was assessing the reliability of the scale asking about early events, which is ironic because it was really testing the reliability of their memories.

Impressively, fully half of the dream interpretation group reported increased confidence in their belief that they were either lost in a mall or had been bullied by an older child before the age of 3.

Of these people, half produced concrete reports of the events having occurred.

They actually built on the dream interpretation to fabricate memories of their own.

This was despite previously being fairly certain these events had never occurred.

In the control group, however, only a few people increased their confidence the childhood event had occurred.

In addition, 30 percent of the control group actually reported decreased confidence they had been bullied or were lost as a child compared to only a few percent of the dream interpretation group.

This suggests the dream interpretation group hadn’t simply had their memories jogged.

Also, suggestibility varied significantly between people.

In this study, those who believed in the power of dream interpretation were more likely to change their beliefs and generate false memories.

The power of dream interpretation

Despite these impressive results, this experiment probably under-estimates the power therapists could potentially wield over their clients’ beliefs and memories.

The experiment examined only people visiting a ‘clinical psychologist’ who they had never met before and about whom they probably had few expectations, other than that they were apparently a dream expert.

Real clients visiting their real therapist are probably much more invested in the relationship and hence probably much more open to suggestion.

Hopefully, of course, the strength of the therapeutic relationship can be used to make positive changes, but it is worth remembering that there are two sides to the coin.

Long history of dream interpretation

Part of the reason people sometimes place so much belief in dream interpretation is because of the long cultural history of dream interpretation which we are regularly reminded about in books, films and on TV.

But it’s more than just that.

Morewedge and Norton argue that there is also a basic psychological process supporting people’s belief in dreams interpretation.

We have random thoughts all the time, like day-dreaming about getting a raise at work.

If a thought comes while awake, it can be consciously dismissed as wishful thinking.

But when the same thought comes during a dream, it’s harder to dismiss — hence dream intepretation.

Although logically impossible, dream interpretation makes it feel like dreams come from outside ourselves.

Along with the long cultural history of dream interpretation, their apparently mysterious source may be partly why some people find dreams so influential.

Sigmund Freud is famous for his psychoanalytic theory and despite modern criticism, he presciently realised that cognitive processes are unconscious.

Sigmund Freud is one of the most famous figures in psychology.

He is best known for the method of psychoanalysis, which is a set of psychological theories and methods used to treat neuroses.

Therapy using psychoanalysis aims to release repressed experiences and emotions from the unconscious in order to facilitate the healing process.

Sigmund Freud and psychoanalytic theory

Sigmund Freud’s theory is that psychological problems are rooted in the unconscious mind.

The symptoms of these disturbances are seen in the symptoms of mental illness.

Sigmund Freud believed that the process of bringing the repressed conflicts to consciousness helps a patient deal with them.

Sigmund Freud’s theories have been extremely influential, leading to expressions like ‘denial’, ‘repression’ and ‘Freudian slip’ entering everyday discourse.

Sigmund Freud thought the personality had three major elements:

• Id: the most basic drive for pleasure, satisfaction of desires and wants.
• Ego: tries to satisfy the desires of the id in the most socially acceptable way. Freud explained the id was like a horse and the ego its rider.
• Superego: upholds moral standards often gained from parents and society.

Freud’s patients

Sigmund Freud’s theories and treatments were based on case studies of patients he had treated and those he had discussed with other doctors using similar methods.

Some of the most famous of these were:

• Anna O., who had hallucinations, paralysis and speech problems.
• Little Hans (Herbert Graf) who had a phobia of horses.
• Dora (Ida Bauer) who lost her voice.
• Wolf Man (aka Sergei Pankejeff) who was depressed and dreamed of wolves.
• Frau Emmy von N. is described in detail below…

Methods of Sigmund Freud

The problem for Sigmund Freud’s method was that if the key to mental healing is in the unconscious, how can it be accessed?

So, Sigmund Freud had to develop a series of techniques that he thought could reveal hidden neuroses.

The interpretation of dreams

Freud thought that the interpretation of the dreams was the ‘royal road to the unconscious’.

While were are asleep, he though, ideas that we would normally repress come to the surface.

Since dreams often make little sense, they need interpretation — Freud and other practitioners of psychoanalysis need to work out what they mean.

Free association

Sigmund Freud used free association as another method to access the unconscious.

This often involved saying a word to the patient and asking them to respond with the first thing that comes to mind.

Fragments of the true repressed problem are supposed to emerge through this method.

Freudian slip

Sigmund Freud believed that aspects of people’s unconscious mental processes were revealed by slips in speech.

In other words, we sometimes say what we really mean by accident.

He thought there were accidents and that every behaviour had a meaning, if only it could be correctly intepreted.

Modern view of Sigmund Freud

The strange thing about Sigmund Freud is that, amongst psychologists, his stock is relatively low.

One of the main reasons his work is not considered ‘scientific’ is the apparent difficulty of testing his theories.

Actually there is plenty of scientific evidence for his most important finding – the cognitive unconscious – but it has taken some time to be acknowledged.

Indeed, Sigmund Freud made some startling contributions to psychology only accepted into the mainstream of academic research in the last few decades.

To really understand the revolutionary nature of Sigmund Freud’s work you need to do something for me: to forget you’ve every heard of him or his ideas.

Imagine travelling back to the 19th century and here is a smartly dressed young man looking at you with bright intelligent eyes and there is a pungent smell in the room of cigars.

The case of Frau Emmy von N.

Frau Emmy von N. was one of the earliest patients to be treated with the nascent techniques of psychoanalysis and psychoanalytic theory.

Frau Emmy suffered from a series of tics, some facial, the most obvious of which was a loud ‘clacking’ noise.

To Sigmund Freud the symptoms she showed were typical of hysteria and he soon set about treating her with his strange new methods.

And what strange methods they were.

He talked to her.

Talking to a patient?

What good could that do?

He hypnotised her and soon she began to speak of her frightening experiences – being a maidservant in an asylum, nursing her dying brother.

Then Sigmund Freud did something more unusual.

He let her give full vent to her emotion.

Later, after she had calmed down a little, she seemed better…

Freud’s interpretation

What then did these past events in Frau Emmy’s life signal to Sigmund Freud?

What was the connection to her current symptoms?

At this time Sigmund Freud had begun to develop a psychoanalytic theory that physical symptoms could be caused by thoughts not available to the conscious mind.

His treatment – the talking, the hypnosis, the hand on the forehead, the free association, the couch – all were designed to try and access this so-called ‘unconscious’ world, to find the root-cause of distress.

Once this root-cause could be identified and explained, Freud thought, the physical and psychological symptoms would be alleviated (Breuer & Freud, 1893).

The cognitive unconscious

It was in Freud’s work ‘Project for a Scientific Psychology’ (Freud, 1895) that he first laid down the radical (at the time) idea that cognitive processes are intrinsically unconscious.

We are effectively cognitive icebergs with most of our ‘thoughts’ occurring below the water line, out of conscious perception.

The fact that this idea is no longer considered radical is testament to the last few decades of research which have shown the importance of unconscious processes.

We now have abundant evidence for unconscious processes in the operation of memory, affect, attitudes and motivation (Westen, 1998).

And so, far from being unscientific and untestable, Freud’s theory of unconscious mental processes was incredibly prescient.

It laid the ground for some of the most important lines of research in psychology today.

Research that tells us more and more about what it means to be human.
