Have you ever wondered why we dream and what those dreams might mean? Scientists have some interesting ideas about why we dream, and they believe there are two main reasons for it.
One reason we dream is linked to creativity. You might have heard about the different stages of sleep. We start with light sleep, move into deep sleep, and finally enter REM (Rapid Eye Movement) sleep. It’s during REM sleep that we actually experience dreams. While deep sleep helps us remember what happened during the day, REM sleep allows us to connect ideas and thoughts that might not have seemed related when we were awake. This is why people often say to “sleep on a problem.” You might wake up with a fresh perspective or a new solution that you couldn’t see before.
The second reason we dream is even more intriguing and involves processing our emotions. There’s a chemical in our brain called norepinephrine, which is turned off during REM sleep. This happens whether we are awake or asleep. Dreams give us a chance to explore difficult or complex emotions without the stress we might feel when we’re awake. For people with PTSD (Post-Traumatic Stress Disorder), high levels of norepinephrine can disrupt this process, making it harder for them to deal with emotional experiences. Even though they remember these experiences, they might not feel as intense the next day.
Understanding dreams can be a fascinating journey into how our minds work. Dreams can sometimes be strange or confusing, but they play an important role in helping us solve problems and deal with emotions. Next time you have a dream, think about what it might be trying to tell you. It could be your brain’s way of helping you understand something important in your life.
Start a dream journal to record your dreams each morning. This will help you notice patterns and themes in your dreams. Reflect on how these might relate to your daily life and emotions. Share your findings with the class to explore different interpretations and insights.
Conduct a simple experiment to understand REM sleep. Track your sleep cycle using a sleep app or a smartwatch for a week. Note the times you enter REM sleep and any dreams you remember. Discuss how your dream patterns might relate to your creativity and emotional processing.
Participate in a workshop where you and your classmates interpret each other’s dreams. Use common dream symbols and themes to analyze what your dreams might mean. This activity will help you understand how dreams can reflect your subconscious thoughts and feelings.
Choose a problem or challenge you are facing and “sleep on it.” Before going to bed, think about the issue. The next day, write down any new ideas or solutions that came to you in your dreams. Share your experience with the class to see how dreams can enhance creativity.
Engage in a class discussion about how dreams help process emotions. Share a dream that helped you understand or cope with a difficult emotion. Discuss how the absence of norepinephrine during REM sleep might aid in emotional processing.

Have you ever wondered why you dream and what those dreams actually mean? Researchers believe there are two main reasons for dreaming. The first is related to creativity. You may have heard about the different stages of sleep: we all start in light sleep, then move into deep sleep, and finally enter REM (rapid eye movement) sleep, where we actually experience dreams. During deep sleep, we consolidate the memories of our day, but it’s in REM sleep that we begin to make connections between things that might not have been obvious while we were awake. This is why people often suggest sleeping on a problem; you may wake up the next day with new insights that you couldn’t have made at the time.
The second reason is even more fascinating and relates to emotional processing. There’s a chemical called norepinephrine that is only turned off during REM sleep, whether you are awake or asleep. Dreams provide an opportunity to explore difficult or emotionally complex aspects of our lives without the influence of stress. In fact, in patients with PTSD, elevated levels of norepinephrine can interfere with this process, making it harder for them to process emotional experiences. As a result, even though they remember these experiences, they may not feel as overwhelming the next day.
