The Imperial Painting Academy in Lin’an was a sanctuary of refined aesthetics, a place where ink and silk conspired to capture the fleeting beauty of the world and the harmonious ideals of the Son of Heaven’s reign. Brushes whispered across fine paper, pigments were ground with meticulous care, and the air itself seemed imbued with the scent of aged ink and quiet concentration. Here, Master Hua An had been a luminary. His depictions of serene landscapes, auspicious cranes, and blossoming peonies were renowned for their technical brilliance and, more importantly, their ability to convey a sense of profound peace and prosperity – qualities highly valued by the court. His scrolls adorned the halls of officials and even graced the private chambers of the imperial family.

  But the light in Master Hua’s work, and indeed within the man himself, had begun to dim, replaced by encroaching shadows of a most unsettling nature. Once known for his cheerful disposition and meticulous attention to detail, Hua An had become withdrawn, gaunt, and plagued by an unnerving restlessness. His eyes, once sharp and observant, now held a haunted, distant look, as if perpetually focused on some inner landscape invisible to others. He worked with a feverish intensity, often locking himself in his studio for days, refusing meals and company, yet the results were increasingly disturbing.

  His recent submissions had caused ripples of consternation throughout the Academy and the Ministry of Rites. A scroll commissioned to depict playful phoenixes amidst auspicious clouds emerged as a nightmarish canvas of writhing, black-feathered shapes tearing at each other under a blood-red sky. A landscape intended to showcase the tranquil beauty of West Lake featured distorted reflections in the water that hinted at monstrous forms lurking beneath, the willow trees along the bank twisted into grasping claws. The brushwork remained technically masterful, even gaining a raw, unsettling power, but the subjects were grotesque, infused with a palpable sense of dread and decay utterly antithetical to his previous style and the court's expectations.

  Whispers followed him like his own shadow. Was Master Hua losing his mind? Had some personal tragedy unhinged his artistic vision? Or was he, perhaps, deliberately creating subversive works, mocking the very ideals he was supposed to uphold? His colleagues avoided him, unsure whether to offer sympathy or censure. His patrons grew wary.

  The breaking point came with a commission intended as a birthday gift for a high-ranking Imperial Censor – a painting of the Eight Immortals crossing the sea, a symbol of longevity and good fortune. What Hua An produced was horrifying. The Immortals were depicted as gaunt, spectral figures, their faces contorted in silent screams, adrift on a sea of black ink that seemed to writhe with tormented faces. The Censor, a man known for his stern adherence to propriety, was reportedly livid, viewing the painting not just as incompetent, but as a deliberate, ill-omened insult. A quiet scandal brewed, threatening Hua An’s career and reputation.

  It was Vice-Minister Lu, head of the Academy and a long-time acquaintance who respected Hua An’s past genius, who decided intervention was necessary. He saw more than just artistic failure or deliberate provocation in Hua An’s haunted eyes and disturbing creations; he saw profound suffering. Recalling hushed conversations about a wandering Daoist priest, Xuan Zhen, known for his unorthodox methods and insight into afflictions beyond the physical, Vice-Minister Lu dispatched a discreet messenger, bypassing official channels, seeking the Daoist’s aid.

  Xuan Zhen arrived at the Academy under the guise of a scholar interested in viewing famous artworks. Vice-Minister Lu received him privately, explaining the situation with hushed urgency, emphasizing Hua An’s previous brilliance and current inexplicable decline. Xuan Zhen listened intently, his calm presence a soothing balm in the anxious atmosphere.

  He asked to see Hua An’s recent works. Laid out in a private viewing room, the scrolls radiated a disturbing energy. It wasn't the heavy miasma of demonic possession or the cold touch of a vengeful ghost. It was something more subtle, yet deeply invasive – a psychic residue, like the lingering echo of a nightmare, woven into the very fabric of the silk and ink. The images seemed to flicker at the edge of vision, the depicted horrors hinting at deeper, unseen torments.

  “The hand is Master Hua’s,” Xuan Zhen observed quietly, tracing a distorted line with his finger, careful not to touch the silk. “But the vision… the vision is tainted. Fouled at the source.”

  He then met with Hua An in his studio. The room was chaotic, filled with discarded sketches, spilled ink, and half-finished canvases leaning against the walls, all bearing the same disturbing hallmarks. Hua An himself looked like a man stretched thin on a rack of sleeplessness. He was initially defensive, almost paranoid, when Xuan Zhen introduced himself as someone concerned for his well-being.

  “They sent you, didn’t they?” Hua An accused, his voice raspy. “The Minister? The Censor? They think I’m mad! They don’t understand! This is the truth I see now!”

  “And what truth is that, Master Hua?” Xuan Zhen asked gently, his gaze sweeping over a sketch depicting a beautiful woman whose face dissolved into a swarm of insects.

  Hua An gestured wildly at his work. “The beauty… it’s a lie! Beneath the surface… there’s only rot, fear… endless falling…” He trailed off, clutching his head. “My dreams… they aren’t mine anymore. Something… comes.”

  Probing gently, Xuan Zhen encouraged Hua An to speak of his nights. The painter described fragmented nightmares, not just frightening, but profoundly wrong. Dreams where landscapes bled ink, where familiar faces melted like wax, where he was pursued by formless shadows that whispered forgotten fears. He spoke of waking exhausted, as if he hadn’t slept at all, the disturbing images lingering, demanding to be painted, his brush seemingly moving of its own accord to capture the lingering horror. He felt drained, not just physically, but creatively, as if his own inspiration was being siphoned off, replaced by this alien dread.

  Xuan Zhen listened, piecing together the symptoms. The stolen vitality, the polluted dreams, the compulsive translation of nightmare into art – it pointed towards a specific kind of entity, one rarely encountered but deeply insidious.

  The narrative has been stolen; if detected on Amazon, report the infringement.

  “Master Hua,” Xuan Zhen said, his voice calm but serious. “I do not believe you are mad. I believe you are afflicted. There are beings that dwell on the borders of sleep, entities that feed not on flesh or blood, but on the very essence of dreams. In the old texts, they are sometimes called Mo (貘), or Dream Eaters.”

  Hua An stared at him, a flicker of terrified recognition in his eyes. “Dream Eaters?”

  “They are often drawn to potent dreamers – artists, poets, scholars – whose minds provide rich sustenance,” Xuan Zhen explained. “Especially those experiencing inner turmoil, whose dreams are already vibrant with strong emotions. This creature… it is likely feeding on your anxieties, your fears, perhaps your artistic frustrations. And like a creature leaving droppings, it leaves behind the residue of its meal – the psychic taint of consumed nightmares – which then spills over into your waking mind and onto your canvases.”

  “Can… can you stop it?” Hua An whispered, hope warring with ingrained skepticism.

  “These beings reside in the liminal space between waking and sleeping, the realm of hun (魂) and po (魄),” Xuan Zhen said. “To confront it, I must meet it on its own ground. I must enter your dream.”

  This was a delicate and dangerous undertaking. Entering another’s dreamscape required forming a psychic link, leaving the practitioner vulnerable. Xuan Zhen made careful preparations in Hua An’s studio that evening. He created a protective circle around the sleeping mat where Hua An would rest, using blessed salt and specific talismans designed to anchor the spirit and ward off external interference. He instructed Vice-Minister Lu, who insisted on staying, to guard the room vigilantly and under no circumstances disturb either of them unless the protective circle itself was breached by an external force.

  Xuan Zhen sat in meditation opposite Hua An. As the painter finally succumbed to an uneasy, exhausted sleep, Xuan Zhen began the ritual. Chanting softly, he focused his own mind, projecting his consciousness, seeking the thread of Hua An’s dreaming spirit. He felt a subtle pull, a shift in perception, and the familiar reality of the studio dissolved around him.

  He found himself standing in a landscape simultaneously recognizable and nightmarishly distorted. It was West Lake, but the water was a viscous, black sludge that pulsed faintly. The graceful bridges were crumbling, skeletal structures, and the elegant pavilions on the shore were warped, leaning at impossible angles. The sky was a perpetual twilight, bruised with sickly purples and greens. The air was thick with the scent of stagnant water and decay. This was Hua An’s dreamscape, polluted by the Dream Eater’s presence.

  A low, guttural sound echoed across the black water. Xuan Zhen turned, his Daoist senses alert. Emerging from the sludge near the shore was the Mo. It was not the benign, tapir-like creature sometimes depicted in folklore. This entity was larger, its form indistinct, shifting like solidified shadow. It seemed vaguely mammalian, but with too many limbs that bent at unnatural angles, and a long, flexible snout that ended not in nostrils, but in a lamprey-like mouth filled with concentric rings of glassy teeth. Its hide seemed to absorb the dim light, and its passage left shimmering trails of psychic residue, like oil slicks on water. It was currently hunched over a weeping willow tree – or rather, what should have been a willow tree. In the dreamscape, the tree was Hua An himself, depicted as a younger, hopeful artist, weeping uncontrollably as the Mo used its snout to siphon shimmering threads of light – his memories, his hopes, his fears – from his dreaming mind.

  The creature sensed Xuan Zhen’s presence. It lifted its head, its featureless face turning towards him. Though it had no visible eyes, Xuan Zhen felt an ancient, alien intelligence regard him – cold, hungry, and utterly indifferent to the suffering it caused. It wasn’t necessarily evil in a human sense; it was simply acting according to its nature, feeding as it always had. But its feeding ground was Hua An’s soul.

  “Leave this place, spirit-feeder,” Xuan Zhen projected his thought, his voice echoing strangely in the dream-logic of the realm. “This mind is not your pasture.”

  The Mo let out a low hiss, a sound that vibrated in Xuan Zhen’s teeth. It released the weeping image of Hua An and lumbered towards the Daoist, its shadowy form seeming to grow larger, more menacing. Illusory horrors erupted from the black lake – twisted figures from Hua An’s darkest fears, specters of failure, monstrous distortions of loved ones – all converging on Xuan Zhen.

  Knowing physical confrontation was likely useless here, Xuan Zhen stood his ground, calming his mind, reinforcing his own psychic defenses. He drew upon Daoist principles of clarity and emptiness, becoming a mirror reflecting the illusions back upon themselves. He didn’t fight the nightmares; he acknowledged their unreality, their origin in Hua An’s fear, amplified by the Mo. As the horrors reached him, they dissolved against his focused tranquility, unable to find purchase.

  Seeing its illusions fail, the Mo lunged, its shadowy mass attempting to engulf Xuan Zhen, to drain his consciousness directly. Xuan Zhen reacted swiftly, not with force, but with focused intent. He visualized a potent symbol of pure Yang energy – the rising sun – and projected it outwards. The dreamscape recoiled from the sudden burst of conceptual light. The Mo shrieked, a sound of static and tearing fabric, its shadowy form contracting, weakened by the pure, clarifying energy.

  It hesitated, assessing this unexpected resistance. Xuan Zhen pressed his advantage, projecting not aggression, but a clear, firm command: Depart. Feed elsewhere. This source is shielded. He amplified the feeling of pure Yang, making the dreamscape increasingly inhospitable for the Yin-aligned creature.

  The Mo seemed to understand. It gave another low, resentful hiss, its form flickering. It cast a final, lingering look at the weeping figure of Hua An, then slowly, reluctantly, dissolved back into the black sludge of the lake, its presence fading like a bad dream upon waking.

  Xuan Zhen maintained his focus until he was certain the entity was gone. He then approached the dream-figure of Hua An, placing a conceptual hand on his shoulder, projecting feelings of calm, strength, and clarity. The weeping subsided. The distorted landscape began to stabilize, the colors shifting towards normalcy, though shadows lingered at the edges.

  Withdrawing his consciousness carefully, Xuan Zhen returned to the waking world. He opened his eyes to find Vice-Minister Lu watching anxiously, the first rays of dawn filtering into the studio. Hua An was still asleep, but his breathing was deep and even, his face relaxed for the first time in months.

  When Hua An awoke later that morning, he felt… lighter. The oppressive weight was gone, the constant hum of anxiety silenced. He remembered fragments of the dream – the terrifying lake, the shadowy beast, but also a feeling of light, of rescue. He looked at his hands, then at the canvases around him. The disturbing images now seemed alien, echoes of a fever passed.

  Xuan Zhen explained what had transpired. Hua An, humbled and grateful, destroyed the nightmare paintings. He rested for several weeks, slowly regaining his strength and peace of mind. When he finally picked up his brush again, his work retained its technical brilliance, but now possessed a new depth, a subtle awareness of the shadows that coexist with light, adding a layer of profound wisdom to his art that surpassed even his former mastery. The Imperial Academy, and the court, marveled at his 'recovery' and the evolution of his style. Only Hua An, Vice-Minister Lu, and Xuan Zhen knew the true price and nature of his inspiration's return.
