We all have dreams. Sometimes they're pleasant, like winning the lottery or getting a promotion at work. Other times, they're more frustrating or even terrifying, like being chased by a bear or being late for an important test.
But why do we dream? What purpose do our dreams serve?
Dreams have fascinated humans for centuries, and this curiosity has led to the study of dreams in various cultures throughout history, including dreams in Ancient Greece, Egypt, and Mesopotamia.
What Is a Dream?
The first question is, of course, what are dreams? Unfortunately, there's no easy answer to this query. Dreams could be interpreted as thoughts that occur during sleep, or they could be seen as a window into the subconscious mind. There are a lot of interesting facts about dreams that are not so well-known.
In psychology, Sigmund Freud believed that dreams were a way for the unconscious mind to process repressed thoughts and emotions. Carl Jung, another famous psychologist, believed that dreams were a way for people to connect with their "collective unconscious" - the shared history and experience of all humanity.
Jung was a big believer in the power of dreamwork - interpreting and analyzing dreams as part of his therapeutic practice. He believed that dreams gave people insight into their own psychological state, allowing them to better understand their motivations, fears, and desires.
Why Do Dreams Happen?
When we dream, our brain is very active. Studies have shown that different parts of the brain are active during different stages of dreaming. For example, the part of the brain that controls movement is active during dreams that involve movement, such as running or jumping. The part of the brain that processes images is also active during dreams, which is why they often seem so realistic.
Different Stages of Sleep
There are different stages of sleep, and each stage is associated with different brain activity. The three main stages of sleep are REM (rapid eye movement) sleep, NREM (non-rapid eye movement) sleep, and delta sleep.
REM stands for Rapid Eye Movement, and it is the stage of sleep during which dreaming occurs. REM was first discovered in 1953 by Dr. Michel Jouvet and his team, who observed that when people were awakened during REM sleep, they reported having vivid dreams.
NREM sleep is the deepest stage of sleep, and delta sleep is the stage of sleep when we experience the deepest relaxation.
How Does Dreaming Affect Our Bodies?
The physical effects of dreaming are often overlooked, yet they provide important clues to their meaning. When we dream, our heart rate and blood pressure increase, our breathing becomes more rapid, and our muscles tense up - all in preparation for action as if we're actually doing what we're dreaming about! Even a sudden jolt or muscle spasm called a startle reflex can occur.
All this suggests that our dreams are trying to tell us something important and should not be ignored! By paying attention to the physical effects of dreaming, we can gain deeper insight into their meaning and purpose.
The Role of Dreams
Dreams are a powerful thing, even if we often don't understand them. While the exact purpose of dreaming is still unknown, there are many theories on why we have dreams - from recalling memories to helping us process emotions.

What Influences Our Dreams?
There are a number of things that can influence our dreams. Dreams can be heavily influenced by our thoughts, feelings, and experiences from the day (or days) before. If we're worried about something or we've had a particularly stressful day, those feelings will likely carry over into our dreams.
In addition to our thoughts, feelings, and daily experiences, it is worth noting that external factors such as the full moon can also influence our dreams, adding an intriguing element to the rich tapestry of dream exploration.
Dreams can also be affected by what we eat before bedtime; sugary or spicy foods are more likely to give us strange, vivid dreams. Medications, both prescription and over-the-counter, can also influence our dreams. Some drugs, such as antidepressants, can cause nightmares while others may lead to more pleasant dreams.
Types of Dreams
Dreams come in many shapes and forms. Some dreams are vivid, full-blown sequences that may consist of several scenes, while others can be fleeting or fragmented images. Dreams also vary widely in how much we remember from them after waking up. Below you can see some of the most commonly observed types of dreams.
Common dreams often reflect everyday life experiences.
Recurring dreams may be experienced more than once, hinting at a deeper meaning or message.
Prophetic dreams may provide insight into upcoming events.

Tips for Dream Recall

2. Focus on the emotions present in your dreams - Paying close attention to the feelings that come up while dreaming can give insight into why we have these dreams in the first place.
3. Share your dreams with someone else - Talking to another person about your dreams can help you get a better understanding of why we dream, as well as provide an outside perspective on the emotions and symbols that appear in your dreams.
