A World that cannot Sleep – When dreams reveal unsustainability

A growing body of research shows that the environment shapes the subconscious particularly through its influence on sleep and dreams. Studies in oneirology demonstrate that external sensory inputs such as sound and smell continue to influence the sleeping brain, altering dream emotion and content and the REM sleep.

REM stands for Rapid Eye Movement sleep. It is one of the main stages of sleep and is most strongly associated with dreaming. A healthy adult typically enters REM sleep about 90 minutes after falling asleep, with REM periods becoming longer toward morning. When REM sleep is repeatedly interrupted—by noise, pollution, stress, heat, or anxiety—dreams become fragmented even if total sleep time appears adequate.

Dreams reflect emotional and cognitive experiences we face when awake, meaning that daily environmental stressors, sensory overload, and lived conditions reappear in symbolic form within dreams. Together, these findings provide strong evidence that the outer environment is not merely a backdrop to life but it actively scripts the architecture of the subconscious. It influences how we process emotions, form meanings, and even rehearse our deepest fears and hopes during sleep.

Imagine a typical pattern of most Delhi sleepers.

11:30 pm – 1:30 am

The sleeper struggles to fall asleep, overstimulated by noise, pollution, and the lingering echo of a loud news debate that has no consequence.

Dream: A never-ending panel discussion where smog fills the room, and every attempt to speak is drowned by breaking news.

Meaning: Anxiety, sensory overload, helplessness.

1:30 am – 3:30 am

Dream: The sleeper drives through a city where roads keep splitting into numbered lanes. Road signs change faster than they can be read. Each missed turn adds a new rule to the windshield. Soon the glass is covered in instructions, warnings, and warning stickers. The road continues, but visibility disappears. The car moves only because others push from behind.

Meaning: System overload, bureaucratic suffocation, compliance without direction.

3:30 am – 5:30 am

Breathing becomes shallow due to pollution.

Dream: Running without moving; air thick as cloth; the room sealed shut and humming with air purifiers blink green, selling the illusion of clean air.

Meaning: Physical distress symbolized as existential hopelessness.

Now let us imagine another dream sequence. Have you heard about Landour? Perched near the Himalayan ridgeline, Landour sits among forests, slopes, and long silences shaped by altitude. The mountains impose rhythm and scale, making the mind slow to match them. A typical pattern of a Landour sleeper could be as below

10:00 pm – 12:00 am

Sleep arrives naturally.

Dream: Walking a misty path under a thick tree cover guided by a quiet village dog. Slow, coherent imagery.

Meaning: Psychological decompression, continuity.

12:00 am – 2:00 am

Deeper REM.

Dream: Clouds reshaping into memories, reflective, gentle, unhurried.

Meaning: Emotional processing, calm introspection.

2:00 am – 4:00 am

Dream: Altitude-enhanced imagery. Stars drift lower into the valley, their light spreading evenly, easing the weight of unspoken thoughts.

Meaning:
Emotional settling, quiet reassurance, reduced cognitive load.

4:00 am – 5:30 am

Dawn approaches.

Dream: Sitting with tea on a bench watching the valley, A bird chirping welcoming the morning, perches next to you, friendly and fearless.

Meaning: Emotional safety and grounded presence, where awareness replaces urgency. The bird’s nearness reflects a nervous system at ease—alert but unafraid, present without defense.

Clearly, the subconscious is not sealed off from the external world. The Delhi environment, full of noise, pollution, urgency, and overstimulation, enters the subconscious through micro-channels. Dreams fragment, panic intensifies, symbolic imagery collapses into loops of helplessness. Even in sleep, the body remains in survival mode. Landour, by contrast (at least today), offers silence, pattern, and space. This produces dreams that are cohesive, reflective, and emotionally expansive. The subconscious wanders instead of defending itself.

So, environment does not simply influence behaviour; it scripts the architecture of the subconscious. The subconscious records what the conscious mind edits away. It absorbs the true emotional physics of the place we live.

This connection extends into sustainability. A degraded environment harms not only air and water but also the inner architecture of imagination. Ecological crisis becomes psychological crisis. A polluted world produces polluted dreams. Where we sleep becomes what we dream.

The first collapse, then, is often not external. It happens quietly within, in the realm of dreams. A world that cannot dream well loses its ability to reflect, to anticipate, and to envision change beyond immediate survival. And a world that sleeps in fear does not awaken with courage—it wakes alert, anxious, and reactive, mistaking endurance for strength and adaptation for progress.

Sleep-related disorders are now rising sharply across the world, no longer confined to clinical extremes but spreading quietly through everyday life. Insomnia, sleep apnea, restless leg syndrome, circadian rhythm disorders, and chronic sleep deprivation are increasingly reported across age groups, driven by stress, screen exposure, urban noise, heat, pollution, irregular work hours, and anxiety about livelihoods and the future. Obstructive sleep apnea, once associated mainly with obesity. is now linked to air pollution and cardiovascular stress, while insomnia is strongly correlated with economic and emotional insecurity and prolonged uncertainty. Even parasomnias such as nightmares and night terrors are being reported more frequently, especially after prolonged exposure to crises, pandemics, and environmental shocks. What was once treated as an individual medical issue is now emerging as a population-level symptom of overstimulated, overheated, and emotionally burdened societies, suggesting that the rise of sleep disorders is not merely a health trend, but widespread sleep disruption becomes an early-warning indicator of development paths that are no longer aligned with biological, psychological, or ecological limits.

My Professor Friend heard my interpretation of dreams. He said “Dr Modak, dreams act as a nighttime diagnostic tool, showing which parts of us are overloaded, which are yearning, and which are quietly breaking down. And as the world grows more unsustainable, noisier, hotter, polluted and more uncertain, this instability seeps into the subconscious as well. A planet in crisis produces minds in tension; environmental degradation does not stay outside our windows but enters our sleep, altering the tone, rhythm, and emotional weather of our dreams. What we dream, then, is not merely psychological burnout, but it is an intimate reflection of the world we inhabit and the futures we fear or hope to build.”

He lighted his cigar and continued.

“Sometimes I imagine a future where Apple announces a billion-dollar investment to diagnose why the world cannot sleep anymore. The iPhone, now promoted from productivity assistant to bedside anthropologist, lies quietly near our pillows. Today, it does not record dreams but it does record tossing, turning, shallow breathing and midnight awakenings. But imagine with advanced sensors and AI, new algorithms get to work, correlating broken REM cycles with heat waves, pollution spikes, noisy neighbourhood, unstable jobs, and uncertain governance, iPhones will start your dream diagnosis. In this future, quality of life will no longer be measured by how much people earn, but by how well they sleep and what do they see in their dreams.”

“Well, you are now haluciating Professor” I said and passed the ashtray towards him.

I muttered to myself “the true measure of progress may then be : can a society  sleep with positive dreams and without fear?”

Friends, was I already dreaming?
