The news bulletins flashed across the screens, the anchors wearing somber expressions as they delivered the astonishing report. "In a shocking turn of events, an entire class of students and their teacher have vanished without a trace from Miyst-Yida University today. Ten students and 28-year-old English teacher Eliza Hartley were last seen entering classroom 3B at approximately 2:30 this afternoon. When the bell rang for the next period, the room was found empty, with only a cryptic message scrawled on the blackboard - 'Between the worlds, we wander.' Authorities are currently investigating the scene, but no evidence of foul play has been found."

The news spread like wildfire across every major media outlet. Reporters stood outside the university, their faces illuminated by camera lights as they described the inexplicable disappearance. "Authorities are baffled by the unprecedented event," stated one reporter, as the camera panned over the chaotic scene behind her. "Witnesses report seeing the students and their teacher inside the classroom just moments before their disappearance. When school officials entered shortly after, they found it empty save for that single, mysterious message."

Amidst the media frenzy, you trudged home from another exhausting day at the office. Your navy blue suit felt constricting, your sensible black pumps pinching your feet with each step. Dark circles ringed your weary eyes - sleep had been elusive for years, haunted by the same recurring nightmare. The streetlights flickered on as evening fell, casting long shadows over the sidewalk as you passed Miyst-Yida University, its brick buildings now cordoned off with police tape.

For as long as you could remember, you'd dreamed of a trapped class of students and their teacher, forever ensnared in a parallel dimension within that very school. In your dreams, you could see them clearly - their ghostly figures distorted by the edges of their reality, their voices muffled as if speaking through water. You'd always dismissed these visions as stress-induced nightmares, the product of your overworked mind.

You fumbled with your keys at the door of your modest apartment, eager to escape into the sanctuary of your personal space. The familiar scent of home greeted you as you stepped inside, and you kicked off your shoes with a sigh of relief. Collapsing onto the sofa, you closed your eyes, only to immediately find yourself in that haunted classroom again.

This time, the scene was more vivid than ever before. The students huddled together, some sobbing, their faces etched with despair. Eliza Hartley moved among them, her voice trembling but determined: "Please, everyone, we need to stay strong. We'll find a way out of this, I promise you."

Their desperation was palpable, sending a chill down your spine. As you watched, Eliza suddenly turned toward you, her eyes locking directly onto yours with penetrating intensity. In that moment, you felt a connection unlike anything before - as if she could actually see you through the veil between worlds. Just before you woke with a start, you clearly heard her whisper two words: "Help us."

The shrill ring of your phone shattered the silence of your apartment, making you jump. You fumbled for it in the darkness, your heart pounding. The caller ID showed an unfamiliar number with a local area code. With trembling fingers, you answered.

"Hello?" Your voice sounded hoarse with exhaustion.

"Is this...?" A gruff male voice asked, hesitating for a moment before continuing. "My name is Detective Marcus Sullivan with the Major Crimes Unit. I'm investigating the Miyst-Yida University disappearances. I understand you've been having some... unusual dreams about the missing class. Could I speak with you about them?"
