On nights when I dream a lot, I sometimes wake up in the morning feeling mentally cluttered and tired.

There are days when I wonder why I had so many dreams last night, and this is related to the effects of REM sleep occurring in the brain.

Sleep is divided into several stages, and REM stands for 'Rapid Eye Movement', which is the stage where the eyes move rapidly.

During this time, the brain is actively working almost as if it is awake, organizing memories from the day, refining emotions, and recombining thoughts.

This is why many dreams occur during this period. In other words, dreaming a lot means that the REM stage was long or repeated frequently.

However, dreaming a lot is not necessarily a bad thing. It can be a natural process for maintaining mental health.

That said, dreaming too frequently or vividly remembering dreams may indicate a lack of deep sleep.

When you get less deep sleep, the body has less time to recover, which can lead to feelings of fatigue the next day.

Conversely, many people say, "I slept soundly without dreaming." However, in reality, very few people do not dream at all.

Most people dream but simply do not remember it. Not remembering dreams likely indicates good sleep quality.

However, having no dreams at all is not necessarily a good thing. If the quality of sleep is so shallow that one does not enter the REM stage, it may mean that mental recovery is insufficient.

Ultimately, balance is important. Having too many dreams or too few can both be problematic.

Stress before sleep also has a significant impact on dreams.

If you fall asleep feeling anxious or angry, the brain tries to process those emotions again during REM sleep without fully resolving them. This can lead to anxious dreams or nightmares that feel very real.

This is sometimes referred to as the 'emotional reprocessing process'. Conversely, if you fall asleep feeling calm, the dreams are likely to be relatively gentle and positive. In other words, our emotional state directly influences the content of our dreams.

So, the saying "how you feel before sleep matters" is not without reason. Lastly, many people wonder how taking a shower before bed relates to dreams. Showering temporarily raises and then lowers body temperature, and this temperature change helps with sleep rhythm.

Especially when showering with lukewarm water, the gradual drop in body temperature naturally induces drowsiness. Falling asleep in this state often leads to more stable sleep, resulting in fewer dreams or less memory of dreams.

On the other hand, taking a long shower with very hot water can excite the sympathetic nervous system, which may actually lead to lighter sleep and more dreams. In summary, dreaming a lot is a sign that the brain is actively organizing emotions and memories.

However, frequent or vivid dreams may be a sign of insufficient deep sleep. Stress significantly affects the quantity and content of dreams, and habits that help calm the mind before sleep, such as warm showers, quiet music, or light stretching, can improve sleep quality.

Ultimately, what matters more than whether you dream or not is how recovered you feel in body and mind when you wake up in the morning.

If you wake up feeling refreshed and not tired, that indicates you had a good night's sleep. Dreams are a secondary issue.

Phew, summarizing this long content has made me tired. I also need to get some good sleep now.
