Why Do We Dream?
Almost everyone dreams, though we may not remember most of our dreams.
While we sleep, our brain does not switch off. It remains remarkably active, processing memories, emotions and information.
Dreams are especially common during REM sleep, a stage when brain activity becomes more similar to wakefulness while most of our muscles remain relaxed.
But why do we dream?
Science does not yet have one complete answer.
Dreams may be connected with memory processing, emotions and the brain's way of organising experiences. Sometimes the brain appears to combine fragments of recent events with older memories, creating strange stories that make little sense when we wake.
That is why someone we haven't seen for years may suddenly appear in a dream, or why familiar places can become completely unfamiliar.
And sometimes we wake up wondering:
“Where did that dream come from?”
The truth is that scientists are still studying this fascinating mystery.
Perhaps that is what makes dreaming so intriguing.
Every night, while our body rests, our brain quietly creates a world of its own.
