Vivid dreams: what they mean and why they happen
Clinically reviewed by Dr. Chris Mosunic, PhD, RD, CDCES, MBA
Explore the meaning of vivid dreams and what causes them. Plus, how to stop vivid dreams if you're having them every night.
Everyone dreams, but not everyone recalls the details of their dreams or the emotions associated with them. While some dreams fade quickly from memory, vivid dreams possess a clarity that can stay with us throughout the day.
But what makes a dream so vivid? And do vivid dreams indicate a deeper underlying issue?
Why are my dreams so vivid? Causes of vivid dreams
Some dreams feel mundane and hazy while others seem as real as our waking lives and vivid in their intensity. Here are some of the factors that can amplify the vividness of dreams.
Stress or anxiety: Pressures from your daily life can weave their way into your dreams. They’re the mind's way of processing the day's emotions, decisions, and challenges. If you're navigating a stressful period, you might find your dreams mirroring that tension.
Sleep disorders: Conditions like insomnia, narcolepsy, or sleep apnea can lead to interrupted sleep. And when your regular sleep patterns are disturbed (like in the third trimester of pregnancy), your brain sometimes compensates by plunging you into vivid dreams or nightmares.
Medications: Certain medicines, especially those impacting neurotransmitters in the brain, can lead to vivid dreams. If you've recently started a new prescription and your dreams have taken a dramatic turn, there could be a connection.
Food: Some foods, such as those rich in spices—like that spicy taco you couldn’t resist—can influence dream intensity when consumed close to bedtime.
Substance use: Alcohol and certain drugs can alter sleep patterns and intensity. As these substances are rising and falling in your system, they can greatly interfere with your quality of sleep and how vivid your dreams are.
Mental health conditions: Beyond daily stressors, deeper emotional and psychological challenges like depression or PTSD can increase dream intensity. That’s because dreams are likely the subconscious mind's way of processing these experiences.
While vivid dreams can be fascinating, if they're becoming a nightly occurrence or disturbing your rest, it might be worth exploring their potential causes. Consider seeking a professional opinion.
When do vivid dreams occur?
Every night, we move through different stages of sleep multiple times, from light sleep to deep sleep and then to REM sleep. This is known as the sleep cycle. Dreams can occur anytime during the sleep cycle.
Dreaming in REM sleep: The most vivid dreams tend to happen during REM sleep. This stage is characterized by darting eyes (hence the name Rapid Eye Movement) and heightened brain activity. REM creates the ideal conditions for intense, memorable sequences where dreams feel most realistic.
Dream timing: As the night progresses, our REM periods lengthen, which is why that dream just before the alarm goes off can feel like a full-length feature film.
Dreaming during deep sleep: We also experience deep sleep — when the body focuses on physical recovery. Dreams during this stage are usually less vivid and more thought-like than in REM sleep.
Are vivid dreams a sign of mental illness or other mental health conditions?
The reason vivid dreams occur isn’t entirely understood yet, but most researchers agree there’s no cause for concern. While some people have extremely vivid nightmares, they are usually short lived, and not a sign of any major mental health issue. If however you find that vivid nightmares are affecting the quality of your sleep, it can be helpful to chat with your healthcare provider about this.
How to stop having vivid dreams
Of course, not all vivid dreams are welcome. Sometimes, our dreams can become disturbing and cause stress and anxiety. And while vivid dreams can be a gateway to our subconscious thoughts, consistent unsettling dreams might signal an underlying issue. Always prioritize your wellbeing, and try using our tools and strategies to get the sleep you need.
1. Ensure good sleep hygiene
Prioritize 7–9 hours of sleep, ensuring your sleeping environment is cool, quiet, and dark. Consider using blackout curtains and white noise machines to create a sanctuary that tells your brain it's time to relax.
2. Reduce daytime stress
Stress is often behind disturbing dreams. Engage in activities that calm your mind, like reading, taking long walks, or listening to soft music.
💙 If you’re under pressure at work or in your personal life, Calm’s Stress Meditations can help you overcome daily stresses, which could, in turn, calm your dreams.
3. Use relaxation techniques
Prepare your mind and body for sleep with techniques like deep breathing, progressive muscle relaxation, or guided imagery, which can act as barriers against nightmares.
💙 If sleep disturbances are a concern, drift off to one of Calm’s Sleep Stories to help you get a good night’s rest.
4. Avoid some foods and drinks
Although that late-night glass of wine or pepperoni pizza may seem tempting, certain foods and beverages can influence dream patterns, especially if consumed right before bedtime. Aim to finish eating at least 2 hours before you go to bed, and limit caffeine and alcohol.
6. Limit stimulants in the evening
Whether you’re watching the latest episode of an action-packed box set or reading a thrilling book, intense stimulation before bedtime can turn up in your dreams. Opt for a gentle read or a soothing podcast instead.
7. Seek professional guidance
If your vivid dreams tend to be nightmares or cause distress, seek professional help to help you process and cope with the experience.
💙 In the meantime, if your thoughts spiral out of control, try Slow the Swirl In Your Mind meditation to calm your mind.
Vivid dreams FAQs
What does it mean to have very vivid dreams?
Vivid dreams are your mind painting a detailed and memorable scene during your sleep cycle. Dreams are the brain's way of processing and decluttering, but they can sometimes reflect our daily experiences, anxieties, or even the food we eat.
Are vivid dreams good or bad for sleep?
Dreams are unlikely to affect sleep quality if they are positive or neutral. But if your dreams become excessively intense or nightmares, they might disrupt your sleep.
What's the difference between lucid and vivid dreams?
Vivid dreams are like watching a high-definition movie—everything feels real and immersive. But in lucid dreams, you realize you’re dreaming while you’re asleep. You might even have some control over the narrative.
What causes vivid nightmares?
Nightmares are the more intense cousin of vivid dreams, and they can be triggered by a variety of factors. Stress, trauma, certain medications, or even a big meal right before bed can cause them. Dreams are likely our brain's way of processing tough emotions or situations, so if nightmares persist, consider professional help.
