Many ideas exist about why people dream, but science hasn’t provided a clear answer on what dreams actually do. Different theories try to explain this mysterious aspect of sleep. Some believe dreams help process emotions or memories, while others think they serve as a way for the brain to organize information. Despite these dream theories, the exact purpose of dreaming remains unknown.
To understand more about dreams, it can be helpful to explore the various theories surrounding them. Some suggest that dreams may be a means of problem-solving or preparing for future challenges. Others propose that dreams are a natural part of the brain’s nightly activities.
If you’re curious about your own dreams and want to remember them better, there are some techniques you can try. Keeping a dream journal, where you write down your dreams upon waking, can help improve your dream recall. Additionally, creating a relaxing bedtime routine and getting enough sleep are factors that may contribute to a better understanding of your dreams. While the science of dreaming is still a puzzle, exploring these dream theories and techniques can offer insights into this fascinating aspect of human experience.
What Are Dreams?
Dreams are mental experiences that our brains create while we sleep. They can include images, emotions, and sensations. Although dreaming can happen at any sleep stage, the most vivid and memorable dreams usually occur during rapid eye movement sleep (REM sleep).
Various types of dreams exist, such as healing, prophetic, recurring, lucid, and nightmares. In a single night’s sleep, you may have multiple dreams, each lasting anywhere from ten seconds to forty-five minutes.
Matthew Walker, a sleep expert, describes dreams as visual and filled with motor activity. Dreams often incorporate past autobiographical memories and can evoke strong emotions. They can be irrational, illogical, or bizarre.
Brain science has provided us with neural evidence that helps explain how we experience this unique state called the dreaming state. In essence, dreams add an intriguing layer to our understanding of the complexities of the human brain during sleep.

Theories About Dream
Dreams are mysterious, and scientists haven’t figured out exactly why we dream. Sleep expert Matthew Walker tells us that the idea of where dreams come from has a long and interesting history. Many scientists from different fields like neuroscience, psychology, psychiatry, and cognitive science are trying to understand dreams better.
Here are 7 theories about dreams:
1. Dreams and Emotional Processing
Dreams may serve as a way for individuals to deal with their feelings, according to a theory about emotional processing. Often, dreams are full of strong emotions, and through dreaming, individuals may navigate and resolve emotional issues, helping them become more resilient in their daily lives. The idea suggests that dreaming provides a space for people to grapple with their emotions, making it easier for them to cope with the challenges they encounter regularly.
This process of emotional reflection during dreams could contribute to an improved ability to handle the ups and downs of everyday life. In essence, the theory posits that dreaming acts as a mechanism for emotional exploration and preparation, allowing individuals to better understand and manage their emotions, ultimately enhancing their overall emotional well-being.
2. Dreams and Learning Assistance
Researchers propose that dreams serve the purpose of aiding learning and enhancing problem-solving skills. When individuals concentrate on acquiring a new skill or tackling a difficult problem, their dreams may revolve around the specific activity, assisting them in mastering the task.
The idea is that the dreaming process contributes to the overall learning experience, reinforcing the understanding and application of skills. So, the next time you find yourself immersed in a challenging endeavor, don’t be surprised if your dreams become a valuable ally in the journey of acquiring and honing new abilities.
3. Dreams and Memory Formation
This is one of the dream theories where some scientists suggest that dreams play a crucial role in creating new memories. Even though the exact process is not fully understood, experts in sleep believe that dreaming during the Rapid Eye Movement (REM) stage of sleep assists the brain in organizing short-term memories and transforming them into long-term memories. In simpler terms, when you dream, especially during REM sleep, it might help your brain turn recent experiences into lasting memories.
The details of how this happens are still a bit of a mystery, but the idea is that dreaming serves as a tool for the brain to solidify and store important memories for the long haul. So, the next time you find yourself lost in a dream, your brain could be working behind the scenes to make sure those fleeting moments become lasting memories.
4. Dreams and Mental Organization
Some sleep experts think that when we dream, our brains are doing a kind of mental organizing. As we sleep, our minds sort through all the information we experienced while we were awake. It’s like our brain is arranging things, making important connections between different pieces of information, and getting rid of unnecessary stuff.
Imagine your brain as a neat and tidy room. While you’re asleep, it’s as if your brain is going through all the things you’ve seen and heard during the day, putting them in the right places, and throwing away things you don’t need. This helps your brain work more efficiently when you wake up.
So, when you have those strange and interesting dreams, it might be your brain’s way of making sense of the things you’ve experienced while you were awake. It’s like a nighttime cleaning and organizing process that keeps your mind sharp and ready for the next day.

5. Dreams and Otherworldly Connections
Various religions suggest that dreams serve as a means to reach out to alternate realms or dimensions. Many people find profound meaning in dreamt meetings with departed family members.
According to Matthew, in ancient Roman and Greek cultures, dreams were perceived as divine gifts from the heavens and specific gods. Meanwhile, in Eastern Asian cultures, dreams were thought to originate from within the soul or somewhere in the body. These diverse beliefs highlight the age-old fascination with the enigmatic nature of dreams and their potential connections to the beyond.
The idea that dreams provide a link to otherworldly realms has persisted across different cultures, sparking curiosity about the significance and origins of these mysterious nocturnal experiences.
6. Dreams as Random Brain Noise
According to some scientists, This is one of the dream theories that suggest that dreams might just be random noises created by our active brains. These researchers suggest that dreams don’t serve any specific purpose but are merely a byproduct of the brain’s activity. It seems that the random firing of neurons during sleep may not have any particular significance or special role. In simpler terms, when we dream, our brain might just be producing random thoughts without any clear reason or function.
While some people believe dreams have meaning, others think they’re just a result of the brain being busy during sleep. The idea is that the brain is like a machine that continues to work even when we’re asleep, creating a mix of images and scenarios that don’t necessarily have a purpose.
The ongoing debate among scientists revolves around whether dreams hold a deeper meaning or if they are simply the brain’s way of entertaining itself during downtime.
7. Dreams as Unconscious Desires
Austrian psychotherapist Sigmund Freud’s theory suggests that dreams are manifestations of hidden desires within the unconscious mind. According to Freud, when individuals are unable to express their desires in their waking life, the unconscious mind may act them out as fantasies during sleep. Matthew explains that Freud, in a way, transformed the study of dreams into a branch of brain science or neuroscience.
This is one of the dream theories where Freud proposed that our dreams originate within the minds of each individual, serving as a repository for the act of dreaming itself. By delving into the depths of the unconscious, Freud’s theory sheds light on the mysterious realm of dreams and how unexpressed desires find a voice during the state of sleep.
Different Types of Dreams
While the dream theories discussed above suggest that dreams can take countless forms, they generally fall into several common categories that people frequently encounter. Let’s look into six types of dreams, each with its unique characteristics and potential meanings.
1. Dreams About Flight
Lots of folks have dreams where they can fly. These dreams are usually nice and make people feel really happy. People who have these dreams often think about feelings like freedom, being brave, and feeling strong. It’s like they can do anything in their dreams. Flying dreams can be a great experience where people feel like they have no limits. They might feel like they are in control and not scared at all. It’s as if they have the power to do whatever they want when they’re flying in their dreams.
2. Lucid Dreaming
In lucid dreams, sleepers realize they are in a dream and gain control over their bodies and thoughts within the dream. Lucid dreaming allows individuals to be aware of their dreaming state, enabling them to actively influence and direct their dream experiences. This phenomenon grants a unique opportunity to explore and manipulate the dream world, as dreamers can make conscious decisions and even alter the dream’s course.
The lucid dreamer might choose to fly, confront fears, or simply enjoy a heightened sense of awareness within the dream environment. This state of consciousness during dreaming opens up possibilities for self-discovery, creative exploration, and overcoming obstacles that may appear in the dream realm.
Ultimately, lucid dreaming provides a fascinating avenue for individuals to engage with and shape their dreams in ways that go beyond the limits of ordinary sleep experiences. This type of dream aligns with one of the dream theories about mental organisation.
3. Nightmares
Nightmares are frightening dreams that can make you feel scared. Sometimes, these dreams happen because your brain is trying to deal with things that stress you out every day. There are different reasons why nightmares occur, such as not eating well, going through tough experiences, being sick, not getting enough sleep, having sleep problems, or taking certain medicines.
When your mind is troubled, it can create scary dreams at night. To avoid nightmares, it’s essential to take care of yourself by eating healthy, managing stress, and getting enough rest. If nightmares happen often, it might be helpful to talk to a doctor or a sleep specialist to find ways to sleep better and reduce scary dreams.
Taking small steps to improve your daily habits can lead to more peaceful nights without frightening dreams.

Prophetic dreams are when you see things in your sleep that later happen in real life. Some think this means you can see the future, while others think it’s your mind getting ready for what might happen. People who have these dreams believe they are like a sneak peek into what’s coming. It’s like a movie trailer for your life!

5. Repeating Dreams
People often have the same dreams again and again during one night’s sleep or over several nights. These recurring dreams show similar images and feelings from previous occurrences and might even turn into recurring nightmares.
Experts propose different ideas about why we have recurring dreams. Some think it’s our way of avoiding risks, while others believe it reflects our internal fears or unresolved problems.
In simple terms, recurring dreams are when the same or similar dream happens to us more than once. These dreams can be a bit puzzling, but they might be our mind’s way of working through things that bother us or making sense of our fears while we sleep.
6. Stress in Dreams
Dreams can be influenced by stress, leading to a phenomenon known as stress dreams. These dreams may not be full-blown nightmares, but they are typically uncomfortable and tense experiences. Individuals frequently describe dream scenarios featuring unpreparedness for tests or encountering confusing and challenging situations. Stress dreams often mirror real-life anxieties, manifesting as unsettling dream content.
People commonly grapple with these uneasy dreams, reflecting the impact of stress on the subconscious mind. The dreamer may find themselves navigating through scenarios that evoke tension and discomfort, highlighting the connection between mental stressors and dream experiences. Understanding and addressing stress dreams can contribute to a night of more restful and peaceful sleep, promoting overall well-being.
