共夢市 The Commons of Sleep

The hinge

Sleepers registered to the same municipality dream together, in one continuous civic dreamspace whose geography loosely mirrors the waking city. You appear as you believe you look, you meet whoever else is asleep, and what happens is remembered by all parties in the morning.

What it cannot do

• The Commons maps to your registered sleeping address: change your residence registration and you change your night city. The unregistered sleep in the Fringe — the unzoned dream-outskirts.
• No physical harm crosses: you wake from anything. But memory crosses fully — humiliation, threats, confessions and promises made in the Commons are real, remembered, and legally actionable.
• You appear as you believe you look, which cannot be faked directly; disguise is possible only by genuinely changing your self-image, an art that takes years and leaves marks.
• Children dream in walled gardens by statute until sixteen; the walls are the one public work no budget has ever dared cut.
• Insomniacs, night-shift workers and the sleepless-by-grief are effectively exiled from the night polity — a citizenship gap the law keeps failing to close.

Geography

Every city is two cities: the day town of stone, and its Commons — a looser, taller, permanently lamplit version of the same streets where the whole population meets while lying down. Planning both is one profession and two budgets.

The Night Plaza. The Commons' central square, engineered for reassurance: warm light, low ceilings of sky, fountains that sound like rain on roofs. Riots start here anyway; it's where everyone is.

The Walled Gardens. The children's dream district — hedges that cannot be climbed from outside, weather always one hour before summer dusk. Parents may visit; strangers arrive facing outward and walking away, by design.

The Abatement Ward. Where the city's dream-wardens contain recurring nightmares: a quarantine quarter of fog and screens where trained calmers walk patrol, two by two.

The Fringe. The unzoned dark beyond the last planned street, where the unregistered, the hiding and the exiled dream. No wardens, no walls, no map — and the best music in the city.

The look

A city rendered in lamplight and felt: architecture slightly taller and kinder than by day, streets that curve for comfort, municipal signage in the soft typography of lullabies — and past the last lamp, the unplanned dark of the Fringe.

Peoples

Night burghers. Ordinary citizens who take the Commons seriously: they dress their self-image carefully, keep their dream-conduct clean, and network harder asleep than awake. They prize reputation, composure, a well-kept appearance-of-self. Before big nights — trials, proposals, elections — burghers 'sit for the mirror': an hour of coached self-regard, because you appear as you believe you look, and belief can be groomed.

Dream-planners and wardens. The night civil service: planners who lay out the Commons' streets by influencing the city's shared expectations, and wardens who walk it. They prize calm, proportion, the ethics of influence. Planners publish the night plan in the day press before any change — a plaza cannot be moved until enough citizens expect it moved — so all urban planning is, openly, persuasion.

Fringe sleepers. The unregistered: migrants, debtors, artists dodging the reputation economy, and everyone the walls were built without. They prize anonymity, improvisation, mutual aid. Fringe custom forbids asking anyone's day-name. What you are called in the dark is what you answered to when someone first needed you — and the names are earned, and kept.

Law

Cities are governed twice over: day councils for stone, night commissions for sleep. The two share a treasury and dispute it eternally; the constitutional formula — 'one city, two sides of the pillow' — settles precedence in favor of whichever side can show harm.

• The Dream Conduct Code — Whatever happens in the Commons is remembered by all parties, so the first generation of night courts drowned in he-dreamed-she-dreamed. The Code defines assault, fraud and harassment for a realm without bodies — memory is the injury, and it is enough.
• The Walled Gardens Statute — The case that built the walls is taught, not named. Every child sleeps behind hedges until sixteen; approaching a garden wall from outside, in any form, is the night code's gravest offense.
• The Nightmare Abatement Act — One man's recurring factory-fire dream burned through a district's sleep for a month — shared space means shared symptoms. Chronic nightmares are a public-health matter: treated free, contained humanely, never punished.
• The Commercial REM Licensing Law — Advertisers discovered the Commons in its first decade and papered the Night Plaza with jingles people could not wake from. Commerce in dreamspace now requires a licence, a curfew, and — after the Lullaby Riots — a total ban on targeting the newly bereaved.
• The Registration Equity Bill (failed, refiled annually) — Your registered address decides your night city, so landlords sell 'dream-postcode' premiums and the poor sleep in the Fringe. The bill to unbind dream-residency from property has failed eleven times, and its annual refiling is the Commons' loudest ritual.

Economy

Currency: Day money is ordinary coin; the Commons runs on standing — formalized night-reputation, banked by witnesses — because nothing physical can change hands while everyone is lying down.

Sleep is where the city actually meets, so the night hosts its true markets: introductions, negotiations, auditions, betrothals and verdicts-in-waiting. Day commerce executes what night standing arranges.

A day in the life

Morning. The city wakes and compares notes: last night's Commons is the morning's news, and 'did you see—' means the same thing to everyone.

Food. Supper is civic strategy — heavy sleepers dream deep and steady, so the night-ambitious eat early and well, and the cafés sell 'plaza blends' timed to your bedtime.

Work. Day work executes night arrangements; the liminal professions — planners, wardens, mirror-coaches, standing-notaries — are the city's fastest-growing payroll.

Night. The real commute: the whole city lies down within the same hour, and the lamps of the Commons come up on everyone at once.

Live tensions

• The registration system chains the night city to the property market, and the Fringe grows every year — a shadow polity of the unregistered that the Commons pretends is empty and increasingly, audibly, is not.
• Someone in the city has learned true disguise — appearing as someone else entirely — which the law calls impossible and three night-court cases now suggest is merely expensive.
• The day council wants to sell licensed 'quiet hours' in the Commons to fund the walls; the night commission calls it privatizing sleep, and both sides are right about the other.

Story seeds

• A warden patrolling the Abatement Ward recognizes the recurring nightmare's setting: it is her own childhood kitchen, remembered by someone she has never met.
• The night before the verdict, every juror in a murder trial is visited in the Commons by the victim — or by someone wearing the victim's believed face, which the law says cannot be worn.
• A Fringe musician's melody starts appearing in registered citizens' dreams across three districts, and the licensing office must decide whether to prosecute the first unlicensed artwork the whole city loves.
• A child's garden wall develops a gate no planner drew, opening from the inside — and the children, who tell each other everything, have agreed not to tell the adults where it goes.

• Two sides of the pillow — The constitutional formula for one city governed twice — by day for stone, by night for sleep.
