Dreams continue to be one of the final frontiers of human understanding. For centuries, we've sought to make sense of why our minds construct such strange, otherworldly realms while we sleep. Now, science is beginning to delve into the process of dreaming, exploring why we dream, what happens during these moments, and what it all really means. Surprisingly, some of the connections between our waking life and the surreal world of dreams are truly astonishing.
10. Loneliness Enhances Dream Activity
Everyone dreams, but not in the same way. This was a key discovery made by neurologist Patrick McNamara in 2001 when he explored how social connections influence dreams. His research team worked with 300 college students, assessing their attachment styles—how comfortable they were with intimacy and their tendency to avoid relationships. Attachment styles were categorized as either ‘secure’ or ‘insecure.’
McNamara discovered that students who scored high on the insecure attachment scale consistently reported having more dreams each night, with more vivid and detailed accounts compared to their securely attached peers. Interestingly, the dreams of the insecure group were often described as far more intense and disturbing than those of the other group.
Given that the anterior temporal cortex is key for both attachment and REM sleep, it’s possible that increased dream activity compensates for the lack of attachment in certain individuals. In any case, it results in heightened brain activity throughout the night.
9. Video Games Trigger Lucid Dreams
Lucid dreaming is the remarkable ability to recognize that you're dreaming while it's happening. Once you realize this, you can take control—fly, engage in intimate moments, or even combine both. Unsurprisingly, many people seek this experience nightly, and books have been published promising to teach the art of lucid dreaming on command. It turns out, though, that playing video games may be the key to unlocking this ability.
Jayne Gackenbach from Grant MacEwan University suggests that the environmental control and spatial awareness developed through gaming mirrors the perception of a dream environment. This makes it more likely for gamers, compared to non-gamers, to gain control of their dream world and experience lucidity.
She also found that gamers were less prone to nightmares—when faced with threats in their dreams, they confronted them, turning the situation into a challenge rather than fleeing.
8. Animals Have Dream Memories
The long-standing question of why we dream has found a surprising answer—thanks to rats. Matthew Wilson at MIT discovered that when rats were trained to navigate a circular track, their brain activity followed a distinctive pattern. Later, Wilson observed the rats' brains while they slept, and in about half of the rats, the same neuronal activity occurred during REM sleep, indicating the rats were replaying their journey in their dreams.
The scans were so similar that the researchers could compare them and pinpoint where the rat was in its 'dream' loop. This suggests that the rats' brains were storing the information by replaying it at the exact same speed as it occurred in real life. Wilson believes one of the primary functions of dreams is to reinforce memories. This is likely why you're more likely to remember something if you learn it right before going to sleep.

7. Amnesiacs Experience the Strangest Dreams
If dreams are connected to memory, what happens when you suffer from amnesia? The answer: You have no idea what you're dreaming about, but you still dream. Amnesiacs typically cannot form new 'declarative' or 'episodic' memories—such as facts or temporal references (like when or where you learned something). However, when amnesiacs were asked to play the game Tetris, they dreamed about it later, even though they had no memory of the game by the time they went to sleep.
As the amnesiac participants were drifting off to sleep, they were awakened and asked what they had seen in their dreams. Three out of five reported seeing 'falling, rotating blocks,' even though they had no prior knowledge of the memory. Since a key aspect of dreaming involves consolidating recent memories, it appears that amnesiacs are frequently bombarded with such odd and unfamiliar imagery. While most of us can recognize elements from our waking life in our bizarre dreams, for amnesiacs, the images seem to appear out of nowhere.
6. Strange Dreams Are Part of a Sorting Mechanism
The Tetris amnesiac study led Dr. Robert Stickgold, the study’s author, to propose another theory about dreams, particularly their weirdness. He observed that amnesiacs could retain images from experiences even though they couldn't consciously recall them, and the brain would then replay these images during sleep.
His theory suggests that these bizarre dreams—like being at a restaurant with your fifth-grade softball coach, where the chairs are made of jello and your dog is the waiter—represent the brain indexing various stimuli to find connections. The brain pulls up the memory of your dog and compares it to what it knows about your coach to determine if they should be linked. As Dr. Stickgold explained, the brain is 'looking for cross-references—does this fit with this? Sometimes it does, and sometimes it doesn’t.'
A separate study found that the level of strangeness in dream reports increased with greater activity in the right amygdala, a region linked to memory formation. This lends significant support to the idea that the more bizarre a dream is, the harder the brain is working to establish connections.
5. Dreams Might Predict Future Events
As a note, we’ll explore both perspectives on this matter.
In the 1960s, Maimonides Medical Center in New York conducted a series of paranormal experiments, one of which focused on precognition—seeing the future. Participants were divided into two groups: one stayed awake and focused on a specific image, while the other group fell asleep. Researchers woke the second group during REM sleep and asked them to describe their dreams. The intriguing part? The majority of the people in the second group described images that matched exactly what had been 'sent' to them.
Another example from the 60s involves a tragic event in Aberfan, South Wales, where a coal slag pile collapsed after heavy rainfall, burying a school and killing over a hundred people. A psychiatrist named John Barker visited Aberfan to ask residents if they had dreamed about the disaster before it occurred. He gathered over 30 reports of dreams that predicted the event. Thousands of similar cases exist, even appearing in peer-reviewed medical journals. How is it that so many people dream of disasters before they happen? Even Abraham Lincoln was said to have dreamed about his assassination.
Alternatively, there may be a simpler explanation: The Law of Large Numbers. Here’s a clear example from Richard Wiseman:
'Let’s imagine a random person from Britain, whom we’ll call Brian. Let’s assume Brian dreams every night from age 15 to 75. With 365 days in a year, that means Brian will have 21,900 nights of dreams. Let’s say an event like the Aberfan disaster happens once in a generation, and we randomly assign it to any given day. If we assume Brian will only remember dreaming about such a tragic event once in his lifetime, the chances of him having that 'disaster' dream the night before the actual event is about 22,000 to one. However, in the 1960s, there were about 45 million people in Britain, meaning we would expect roughly 2,000 people to experience this phenomenon in each generation. This is known as the Law of Large Numbers, which states that unusual events are more likely to occur when there are many opportunities for them.'
In other words, when multiple factors align, coincidences become more likely. This theory is difficult to prove, but perhaps one day in the future we’ll find evidence that dreams can truly predict the future. Who knows?
4. You Dream More Than You Realize
Despite what many think, we don’t dream exclusively during REM sleep. Dreams can occur in any of the five sleep stages, although REM dreams tend to be more vivid. So, even though we only enter REM sleep about every 90 minutes, we may experience numerous dreams throughout the night.
Why don’t we recall all of them? The simple answer: Because they’re boring. People are far more likely to remember dreams that are strange or unusual. The rest are often ordinary, featuring realistic activities like folding laundry or checking the mail. Much like the rats from earlier, our brains spend a lot of time revisiting these actions in order to consolidate memories and learn from them.
But the outlandish ones—especially those you wake up in the middle of—leave a lasting impression, much like if you encountered something truly bizarre in real life, say, a man running naked down the street. While you may forget the hundreds of other people on the street, the nudist will stand out due to how shockingly different he is.
3. Dreaming Is Like A Dose Of Schizophrenia
Speaking of unsettling topics, it’s now understood that dreams closely resemble the disordered state experienced by those with schizophrenia—down to the active regions in the brain. Essentially, schizophrenics’ brains never fully turn off the ‘dream’ switch during the day. In a way, when we dream at night, we’re momentarily slipping into a state akin to schizophrenia, a phenomenon poetically referred to as “our nightly madness.”
Strange, illusory dreams may arise from malfunctioning circuits in the brain—essentially, the brain attempts to forge a connection, but ends up creating a jumbled mix of unrelated memories, resulting in bizarre dreams. These types of dreams are common to everyone. However, in conditions like schizophrenia, these faulty circuits activate randomly, creating the same experience as illusory dreaming, but while the person is awake.
So, the solution? Just avoid sleep altogether.
2. Nightmares Can Have a Lasting Impact on Your Mood
Feeling anxious, down, or neurotic? Your nightmares might be to blame. A study conducted on 147 students required them to fill out a questionnaire every morning for two weeks to track their nightmare frequency. At the end of the study, their psychological health was assessed using the EPQ-RS and the POMS-BI, two tools designed to measure mental well-being.
The findings revealed a clear correlation between the number of nightmares experienced and the participants’ psychological state during the day. Those who had more nightmares tended to score worse on mental health evaluations. While it’s possible that people who are already depressed have more nightmares, which seems to be the case, it’s also clear that nightmares can affect your waking life. Creepy, right?
1. You Can Influence Dreams With Smell
It’s widely known that external factors, like light, sounds, or even the ringing of an alarm clock, can invade our dreams, but some elements can actually transform the entire mood of a dream—turning a pleasant dream into a nightmare or vice versa. For instance, smells can have a powerful impact on the direction of your dreams.
In one study, researchers allowed participants to fall asleep while pumping different scents through a nasal tube—either the smell of rotten eggs, roses, or nothing as a control. Upon waking, participants were asked about their dreams. Those who inhaled the smell of rotten eggs reported that their dream's emotional atmosphere drastically shifted, even if the dream had no apparent connection to the smell. One participant described dreaming about a Chinese woman who suddenly seemed repulsed by her for no reason, and the tone of the dream altered almost immediately.
