Sleep is something we all do, yet it remains one of the most mysterious aspects of our lives.

Why Do We Sleep?
At first glance, sleep might seem like a waste of time. After all, we spend roughly one-third of our lives unconscious. However, sleep is far from unproductive. It’s the body’s time to repair, recharge, and reset.
During sleep, your brain consolidates memories, strengthens neural connections, and clears out toxic waste. Physically, sleep helps regulate your immune system, balance hormones, and maintain cardiovascular health. In short, skipping sleep is like skipping maintenance on a car—it might work for a while, but eventually, it’ll break down.

What Are Dreams?
Dreams are one of sleep’s most enigmatic features. They occur during the rapid eye movement (REM) stage of sleep, when brain activity is almost as high as when you’re awake. While scientists haven’t pinpointed exactly why we dream, theories range from processing emotions to rehearsing survival skills.
Sigmund Freud famously suggested that dreams are a window into our subconscious desires. Modern science, however, leans more toward the idea that dreams help us process the chaos of daily life. Ever had a bizarre dream after a stressful day? That’s your brain trying to make sense of things.

Sleep Disorders: When Things Go Awry
Not everyone experiences sleep as a peaceful escape. Conditions like insomnia, sleep apnea, and night terrors can turn bedtime into a nightmare. Even stranger are phenomena like sleep paralysis, where you wake up but can’t move, and lucid dreaming, where you become aware you’re dreaming and can control the narrative.
For sleepwalkers, the line between sleep and wakefulness blurs entirely. Some people even cook meals or drive cars while sound asleep!
