How Your Dreams Shape Your Morning Mood: What New Research Reveals

Sleep is a key part of staying healthy, but scientists are still learning how your dreams affect how you feel when you wake up.

A new study published in the journal Sleep suggests that the emotions you experience in your dreams may influence your mood the next morning. The research does not prove that bad dreams directly cause a low mood, but it does show that feelings of fear or joy during sleep may play a role in your mental well-being. The authors say more research is needed.

“Dreams are such a popular topic in therapy. I find that clients often ask about dream interpretation and trying to understand their meaning, or link their significance to daily life,” said Nicole Andreoli, PhD, a licensed psychologist and author who was not involved in the study. “This is especially true for the more emotionally charged dreams because they do tend to influence morning mood. Many of my clients talk about subsequently waking up experiencing anxiety or depressed mood due to the content of their dreams,” she told Healthline.

Fear-Based Dreams Linked to Low Morning Mood

The study used data from the Boston College Daily Sleep and Well-Being survey. Researchers looked at 1,518 participants aged 18 and older. Over a year and a half, participants completed up to 55 surveys. The surveys asked about bedtime, how long it took to fall asleep, time spent awake during the night, and when they last woke up. Participants also reported how well they remembered their dreams and rated their morning mood.

The results showed that people who experienced fear in their dreams were 7% more likely to have a low mood in the morning. Those who had dreams mixing both joy and fear were about 20% more likely to wake up feeling calm. Meanwhile, people who had dreams with a high level of joy were 9% more likely to wake up in a positive mood.

“It has been proposed that REM sleep, in which dreaming occurs, is almost a virtual therapy or sandbox environment,” said Alex Dimitriu, MD, a psychiatrist and sleep medicine specialist who was not part of the study. “In the dream state, and absent any norepinephrine (adrenaline), the brain replays emotional experiences to plans for future ones. Dream sleep is like an emotional playground for the mind. Building on this, people who have more active dream lives may enjoy the benefit of better emotional regulation. Their sleeping brains have had more time in the sandbox. Fear, primal as it is, may be the emotion that requires the most processing in our dreams.”

The study also found that people who are better at handling their emotions were about 3% more likely to feel a negative effect from fearful dreams the next day. However, people who had more fear in their dreams were also more likely to have stronger emotional coping skills.

“Those who more actively suppress or avoid emotion may experience less emotionally intense or vivid dreams, and therefore, remember them less,” Andreoli said. “[However], those who use healthier strategies to cope with fear, such as acceptance, are less avoidant of negative emotional experiences. They are more open to engaging with negative emotions, such as fear, making it more likely to show up in dreams.”

These findings suggest a complex link between dreams and how your mind works during the day. Fear in dreams may be tied to a lower mood the next day, but the mix of dream emotions and emotional regulation hints that your dreams may play an active role in managing your mental health.

How to Start Your Day With a Positive Mindset

Waking up in a low mood can make it hard to get going. But there are simple ways to shift your mindset.

“A clean break from sleep to wake helps. Get out of bed, get outdoors in the sunshine, and get moving. Music also moves our emotions deeply — for that drive to the office after a rough night,” Dimitriu said.

Andreoli suggested avoiding overthinking your dreams. “Instead, orient to the present moment by naming what’s happening, ‘that dream is still with me’; or narrating what you are doing.”

She also offered these tips to improve your morning mood:

– Open the curtains or window to let in morning light and natural sounds. Natural light exposure can boost your mood.

– Do small movements, such as stretching, yoga, or a short walk, to lift your spirits.

– Engage your senses by listening to upbeat music, lighting a candle, or enjoying a warm drink.

– Avoid electronics. Instead, spend a few minutes journaling, focusing on gratitude, or setting positive intentions for the day.

Can You ‘Hack’ Your Dreams to Improve Your Morning Mood?

You may not be able to fully control your dreams, but you can prepare your mind and body for sleep in ways that may help regulate your emotions.

“There is some evidence that dream rehearsal can help,” Dimitriu said. “Before sleep, journal and visualize the recurring or frightful dream, and come up with a positive ending. Repeat. By doing so, people can sometimes change the outcome.”

He added, “Also, be mindful of what you mentally consume before bed — media can color our dreams and our emotions. Stick to lighter, funny stuff. Laughter is the best medicine, for almost anything.”

Andreoli noted that good sleep habits can improve sleep quality and influence your dreams. To boost your sleep hygiene, she suggested:

– Limiting caffeine and alcohol

– Being mindful of what you watch or read before bed

– Keeping a consistent sleep schedule

– Creating a regular bedtime routine

“Increase lucid dreaming, which is the state of knowing you are dreaming,” she said. “You can do this by keeping a dream journal to help improve dream recall. Over time, this will help strengthen your ability to recognize when you are dreaming, and then to influence what happens next in the dream.”

“Imagery Rehearsal Therapy (IRT) is a form of cognitive behavioral therapy (CBT) that focuses on rewriting bad dreams with a neutral or positive ending. By mentally rehearsing this new version, individuals can reduce the frequency and intensity of recurring nightmares over time,” Andreoli said.
