In a school's hallway, a student who appears to be a girl is walking blindly. It was as if she was seeing nothing, despite her eyesight working perfectly.

Many people would have thought that she is just immersed in her thoughts—but that case wasn't simply that.

She was in another world altogether.

In her mind, was a world created by her. They were not illusions, nor were they her hallucinations, they were her imagination.

A world where everything is different from the reality, a world where her dreams exist.

Imagination is a human's nature, and everybody has one. However, hers was different, almost every encounter to any item will trigger it.

It was because she is diagnosed with Maladaptive daydreaming.

As she was walking, she accidentally bumped onto a wall and hit her forehead. A couple of people saw her, but she was not a bit embarrassed, she was already used to it since it often happened.

She stepped back from the wall, and continued walking towards the exit. She has stopped daydreaming, but then she saw a cat licking its paws near the exit's door which brought her back to her imagination.

"Ah! Kitties sure are adorable, perhaps if people looked a more like them, maybe we would have been cuter?"

She pictured a cat girl's image in her mind, a cat girl doing what a cat does in a body which is similar to a human's. It continued to a point where the topic wasn't about cat girls anymore.

Her daydreaming was once again cut off when a girl of similar age to her put her hand on her shoulder.

The girl was quite a beauty, with her raven black hair and cool blue eyes, she was certainly this school's idol.

"Sky! You're soon going to fall off a cliff if you continue your bad habits!"

The girl nagged to Sky, the student who is diagnosed with Maladaptive daydreaming, Sky was used to this because it happens everyday, she found it annoying but she still understood the girl's reasoning. Her constant daydreaming may lead to such accidents.

Sky chuckled at the girl, she found it sweet that the girl would often remind her of such a thing even if the girl knows that Sky is very much aware of that fact.

"W-what are you laughing at?!"

The girl stuttered at her words, Sky would rarely laugh at her nagging but for the first time she did. She found it unsettling.

"It's just cute that you still choose that metaphor to remind me of my predicament, Diana."

Diana's face burns up of embarrassment, she then pouts.

"Well, I'm just worried for you, I mean—!"

"Yes, yes. I know, you don't have to nag me any further."

Sky cut Diana's statement before it gets out of hand, this is the way Sky usually replies to her when she starts to nag her.

"Whatever, let's just go home."

Diana grabbed Sky's wrist and dragged her out of the school all the way to their homes, the reason Diana does this is so Sky can safely go home. She fears that Sky would one day be swept away by her imagination and get lost or get into a car accident. Luckily, they are neighbors so it wasn't too much of a drag from Diana.

Sky complained about that while they were walking home, although she would still daydream from time to time.

30 minutes later when Sky have finally reached her home and escaped Diana's wicked dragging, she went to her room first like any other shut-in would have done.

She threw herself on her bed without changing her clothes, then instantly fell asleep, it was such a long day for her after all.

Tik, tok. Tik, tok.

Sky suddenly heard loud noises, that seem to be coming from a clock as large as the London Tower's clock, that woke her up.

"Huh...? What was that?"

She got up, she inspected her surroundings and she figured out that she was in an unusually large room. Everything in the room had clocks in it, except for the floor that is pitch black.

She felt scared. Why was she here?

She looked for an exit, she attempted to pry open the clocks on walls but none budged, there was nowhere to go out to.

Tears started to fall down on her face, she was fearful.

She tried to rely on her imagination to calm herself down, but for some reason, all her mind can think of was... nothing.

When she figured that she was going to be stuck in this room for a while, she laid down on the floor with her last shred of hope—sleep.

"I was sleeping when I got here, perhaps if I sleep once again I would be back in my room and this was all a bad dream."

All she could do was hope that that was the case.

But it was not.
