A lot of people hear music in their dreams. As someone who writes songs for a living, my experience with this goes deeper than most. Here's what's actually happening.

Yes, you can hear music in your dreams. Not just fragments of songs you already know either. Full melodies, original compositions, lyrics that feel like they arrived from somewhere outside of you. If you have experienced this you are not imagining things and you are not alone.

As a musician who spends a significant portion of my waking life thinking about, writing, and recording music, my relationship with music in dreams is something I have paid close attention to for years. Here is what I understand about why it happens and what it actually means.

What Is Happening in Your Brain

During REM sleep, the phase where vivid dreaming occurs, your auditory cortex stays active. That is the part of your brain that processes sound in your waking life. The fact that it does not fully shut down during sleep is why you can experience sound so vividly in a dream even though nothing is actually playing.

Your brain during REM is not passively resting. It is consolidating memories, processing emotions, and making connections between experiences in ways it cannot do as efficiently during waking hours. Music is deeply tied to memory and emotion, which means it gets pulled into that process regularly. A song you heard earlier in the day, a melody that has been sitting in your subconscious for weeks, an emotion you have not fully processed yet, any of these can surface in a dream as sound.

The brain is also genuinely capable of composition during sleep. There are documented cases of musicians waking up with fully formed musical ideas they had no conscious awareness of before they fell asleep. Paul McCartney famously woke up with the melody to Yesterday completely intact and spent days afterward asking people if they had heard it somewhere before because he could not believe he had actually written something that good in a dream. Keith Richards recorded the riff to Satisfaction on a tape recorder he kept next to his bed for exactly this reason.

This is not mystical. It is your brain working.

The Different Ways Music Shows Up in Dreams

The most common experience is hearing a familiar song. Something you have been listening to recently, a track tied to a specific memory or relationship, a song that was playing in the background of an important moment in your life. Your brain files music alongside the emotional context it was attached to, and when you are dreaming and processing those emotions the music comes with it.

The more interesting experience, and the one I find more personally relevant, is hearing music that does not exist. Original melodies, sometimes with lyrics, sometimes fully arranged with instruments. The brain constructing something in a dream state that feels genuinely new.

I have had this happen more times than I can count. You wake up and the melody is there for a few seconds and then it starts to fade, which is one of the more genuinely frustrating experiences in a musician's life. The ones I have managed to hold onto long enough to get something recorded or notated have occasionally turned into real songs. The ones I lost are a separate kind of loss.

There is also what I think of as the soundtrack dream, where music is not the subject of the dream but the atmosphere of it. Whatever is happening in the narrative of the dream has a musical backdrop that matches its emotional register, the way a film score works. You are not consciously hearing a song. The music is just the emotional texture of the scene.

Why Musicians Experience This Differently

I think musicians hear music in dreams differently than people who are not deeply embedded in making music, not because our brains are built differently but because of how much time we spend with music as a conscious practice.

When you spend hours every day thinking about melody, arrangement, lyrics, and sound, those thought processes do not clock out when you fall asleep. They keep running. The brain continues working on musical problems during sleep the same way it sometimes surfaces the solution to a work problem you were stuck on, except the output is sound instead of an idea.

Writing songs like Tears or Identity required me to go to places emotionally that are not always comfortable to sit in while you are awake and in control of your thoughts. Dreams remove that control. Some of what ended up in those songs came from emotional territory I first encountered in dreams before I had the waking language to articulate it.

Music and dreams access the same part of human experience. They both operate below the level of rational thought. They both deal in emotion and memory and things that are hard to say directly. The overlap makes sense.

What to Do If You Hear Original Music in a Dream

Get something recorded or written down before you do anything else. Before you check your phone, before you get up for water, before you let yourself fully wake up. The window where dream content stays accessible is short.

Keep a voice memo app on your phone within reach. Hum the melody into it the moment you wake up. Even a rough approximation is better than nothing. A few notes on paper, a phrase from the lyrics, whatever you can capture before it dissolves.

Most of it will still fade. That is just the nature of dream memory. But the times it does not fade are worth setting up a system for.

The Short Answer

You can absolutely hear music in your dreams, whether that is a familiar song your brain has filed alongside a specific memory or something entirely new that your subconscious constructed overnight. It happens because your auditory cortex stays active during REM sleep and because music is too tied to emotion and memory to stay out of the dreaming process.

For musicians it goes a step further. The creative process does not fully stop at night. Some of the most honest creative work happens when the conscious, critical, second-guessing part of your brain is out of the picture.
