"The Box"

Have you ever glanced in a mirror and admired, not only your reflection but the grand detail of the small things behind you, how it's not like looking at a mirror, but instead a window, peering into another world? Have you ever wondered what the world would be like on the other side? What if it was your own reflection looking back at you as you're distracted?

He picked up another cardboard box from the garage and carried it over to the living room. As he carried it, he looked around the room, admiring it for this would be the last time it would ever look like this, like home, before the move. He wasn't feeling saddened, but instead, he felt comfortable. No place had ever felt more like home than the house he shared with his wife.
He sat the box in front of his couch, just next to the coffee table. The table was littered with coasters, as well as little odds and ends things that he'd found on the floor earlier that he wanted to pack, all sitting on top of a checkerboard tablecloth. He admired the little things on the table for a moment, as if this was the last time he'd ever see them. He grabbed a green bouncy ball and was about to drop it in the box- before what looked like the same ball shot up from out of the box and landed on the floor beside him.
Startled, he let out a scream. As he screamed, he must have dropped the ball he was holding, as it was no longer in his hand. Hurried footsteps approached from the other room. Emerging through the doorway was his wife, a worried look on her face.
"What happened?" she asked worriedly, her eyes scanning the room before landing on her confused husband.
"You're not going to believe me," he said, staring at the green ball on the floor. He bent down and picked it up, eyeing it over. "This ball came out of the box. The exact same ball that we have."
"Are you sure it's not the same ball and it just bounced out?" she asked, an eyebrow raised and her arms crossed.
In response, his eyes quickly scanned the room for the ball he once had in his hands. It was nowhere to be found. His eyes then turned to the box. Maybe it had landed inside? Unfortunately, the box was empty.
"I don't have time for your little jokes right now," his wife said before turning and walking away. "I have my own stuff to pack."
He felt bad for disturbing her, but it was such a weird thing to have happened. Perhaps he was crazy, perhaps he dropped the ball in the box without realizing it and it bounced out. He tried shrugging the thought from his mind and carried on backing.
As he grabbed things off the table and put them in the box, his mind began to wonder, thinking about what life would be like in the new house they were about to move into. He fantasized about the back patio that lead to an open backyard that his future kids would play in. He imagined all of the extra room they would have and the beautiful bedroom that he and his wife would share.
Turning his attention back to the box, as it must be full by now, he gasped and called for his wife once again. She ran to him, half skeptical that what he was screaming about would be anything other than a joke.
"What's wrong, hun?" she asked, standing in the doorway.
He had his gaze fixed on the empty box, frozen in shock. "I had this box nearly filled," he said. "I'd packed so many things into this box and now it's all gone."
His wife rolled her eyes. "I don't know why you keep messing around when you know we're supposed to have everything packed by tomorrow afternoon. We don't have time for this."
"But I'm not joking around," he said frantically. "Something is seriously wrong with this box."
"Babe, I love you, but please stop messing around and help pack things up," she said before turning and going back to our bedroom to finish packing. "We don't have a lot of time left."
"Great," he sighed. "What else could go wrong?"
As if on cue, the weirdest thing that could happen with the box, came at full force. He wanted to scream as an entire human arm rose from the bottom of the box. It waved itself around like it was trying to feel for something. Slowly, he made his way over to the hand and reached a single finger toward it. He touched it and the hand immediately retreated back into the bottom of the box and vanished. He screamed as it did and he heard footsteps from behind him. It was his wife.
"What the hell is going on now?" she demanded, narrowing her eyes at him. He was speechless, staring at the box in horror.
"If this is about the box again, I swear to god-" she started before he turned to her, still in shock. 
"There was a hand," he said, slowly turning back to the box. "It came out of the box. I touched it and it vanished."
"That's it," she stomped over to the box and attempted to kick it away. In doing so, her foot got caught inside of the box. She screamed as she felt it sink into the box, much lower than it should have been able to.
She felt something grab her foot and pull her even further into the box. Her husband grabbed her arm, hoping to keep her from her fate with the box, but it was no use. Whatever was pulling her was far stronger than himself. She slipped from his grasp and disappeared inside the box.

As she came through, the world around her looked familiar, only upside down. There was this slight blue-ish tint over the world that made it look rather off. She looked at the person holding her by her feet. It was her husband. But her husband looked a little off. She couldn't quite place her finger on it.
He placed her gently on the floor and she looked around, still in shock at what had just happened to her. This was her home. But, once again, it looked a little off. Nothing stood out to her but something felt a little out of place.
She climbed to her feet and looked around. Suddenly her look-alike husband grabbed her arms and called out, "Honey, you're not going to believe who I just found."
Heavy footsteps came thudding into the living room. She was in shock. Whoever it was standing in the doorway looked almost exactly like her. Only she looked over-joyed.
"Oh my lord, honey, it worked!" she proclaimed. "And you know what we must do next."
