Sleep is a realm where our consciousness shuts down, and our mind embarks on mysterious journeys. Dreams are the most complex and fascinating inhabitants of this realm. So, can sounds from the outside world, especially music, play a role in this mysterious world?

Many of us listen to music to fall asleep or relax. It is scientifically proven that music reduces stress, slows the heart rate, and improves sleep quality. But the effect of music doesn't end when we fall asleep; it can seep into the content of our dreams.

During sleep, our brain does not completely disconnect from the outside world. Our sense of hearing remains 'on guard' at a low level, ready to wake us in case of unexpected danger. It is this vigilant ear that can perceive the music playing during sleep.

This perception leads to interesting results, especially during the REM (Rapid Eye Movement) stage of sleep, the stage where dreams are most intense. Our brain takes this external auditory stimulus and tries to integrate it into the dream scenario it is currently constructing.

Scientists call this phenomenon 'dream incorporation'. In studies, when sleeping subjects were played
certain sounds, it was observed that these sounds were included in their dream narratives.

For example, someone listening to a gentle rain sound might find themselves walking in a forest in their dream. Similarly, calm and melodic music can make the emotional tone of the dream more positive and peaceful.

The genre of music playing while sleeping directly affects the emotional atmosphere of the dream. Fast-paced, aggressive music (like rock or electronic music) can lead to more chaotic, stressful, and even nightmare-like dreams.

Conversely, slow-tempo, instrumental classical or ambient music often triggers calmer, more fluid, and sometimes more creative dreams. The music becomes the 'soundtrack' to our dream and sets the emotion of the scene.

So, can we hear a completely 'original' composition in our dream, one we have never heard before? This is a fascinating experience that many musicians and artists claim to have had.

There are famous examples of this in history. Paul McCartney famously said the melody for the legendary song 'Yesterday' came to him in a dream, and when he woke up, he doubted for a long time, 'Did I write this, or is it an old song I've heard before?'

Our brain stores countless musical fragments (notes, rhythms, harmonies) that it is exposed to while awake. During REM sleep, the brain reorganizes this stored information, combines it, and forms new connections.

It is this creative 'remixing' process that can sometimes produce melodic structures that seem completely new and original. The dream is like a studio where our mind turns into an unconscious composer.

Some people experience 'lucid dreaming'. This is a state where the person is aware that they are dreaming and can even control the dream. Lucid dreamers have reported being able to consciously create or change music within their dreams.

This relationship between music and dreams is not just an interesting neurological phenomenon; it can also be a tool for creativity. The type of music listened to before sleep might affect our creative problem-solving skills the next day.

On the other hand, can our dreams influence our musical tastes? If a certain song is playing in the background while we are having a very beautiful and emotional dream, we might develop a strong positive association with that song when we wake up.

This is related to 'emotional memory'. Our brain associates that intense dream experience with the background music. The music becomes an emotional anchor for that dream.

Of course, this experience is not the same for everyone. Some people sleep unaffected by external sounds, while others wake up at the slightest noise. This is related to personal 'sleep depth'.

If you want music to influence your dreams, a few points are worth noting. First, the music should not be too loud; the goal is to gently stimulate the brain, not to wake it up.

Second, instrumental, ambient, or classical music should be preferred over music with lyrics. Lyrics can activate the brain's language processing centers, disrupting sleep or directing the dream scenario too specifically.

Using a sleep timer is also important. Instead of letting the music play all night, it may be more effective to set it for the early stages of sleep or to coincide with REM cycles.

In conclusion, the relationship between music and dreams is a mysterious dance on the borders of consciousness. Music is a powerful tool that shapes our emotional world, not only when we are awake, but even when we are asleep.

As a radio listener, we are aware of this profound power of music. Perhaps your next dream will be composed by that last song playing on your favorite radio station.
