"The Halloween Book"

Horror is a thing that can be debated, is it something that's created or is it something that only exists for the sake of a scare? The answer to this, as most horror stories go, is that horror is something that can easily exist but causes nothing but harm to the people associated with it. But what if it were created out of nothing? Who would do it? And why?

It was Halloween night and my friend, Charles and I, were awaiting the arrival of two other guests, Kara and Michelle. Of course, they were supposed to be our dates for tonight. Well, Kara was supposed to be mine, whereas Michelle was Charles' girlfriend. I was planning on making my move on Kara tonight.
We heard the doorbell ring just as our scary movie had finished. It felt almost as though they'd planned it to try to get out of watching the movie with us.
We all sat down on the couch, next to our dates. Charles put his arm around his girlfriend while Kara and I just sat next to each other, awkwardly chuckling and stealing glances at each other.
I jumped up from the couch to escape the awkward tension and asked the group if they wanted to play a scary game, 'Bloody Goji'. They seemed interested, so I laid down the rules. We all have to take turns in the bathroom. We had to turn off the lights and say, "Bloody Goji" three times fast. If you chicken out and leave before your turn is done, you lose.
Kara already admitted she didn't want to play, so the rest of us did. I went first, then Michelle, than Charles. Nobody chickened out and left early, but it was a scary experience nonetheless.
We all had a good laugh, and I stood by Kara in defending her so that she didn't feel bad about not participating. I felt her cling to my arm somewhat, and it filled me with an indescribably, warm joyous feeling.
We were about to return to the living room when we heard a witches cackle, followed by a dark shadow escaping the opening to the bathroom door. Who was making that shadow appear? I glared at Charles as I noticed Kara freaking out.
"Don't look at me, I didn't do this," he defended himself.
Our eyes followed the shadow to this book that had mysteriously appeared on the coffee table. Now I knew for a fact that Charles had done it, no matter how hard he insisted he hadn't.
We approached the book with curiosity. Charles grabbed it and opened it, each of us looking over his shoulder and gazing at the contents. As he flipped through, I saw things about Unicorns and Yellow Jacket swarms.
Finally, he stopped flipping when he saw the page that had a creeping looking porcelain doll on it. The title below read, 'Summoning the Demonic Doll'. He read it aloud, trying to hold back a laugh as he was doing so. There's no way this book was for real.
Without warning he began to read this foreign language aloud. The way he read it so fluently lead me to believe even further that he had planted the book there.
There was a slight breeze inside the house, then nothing else happened.
We found ourselves looking around in hopes that the doll might appear. After what seemed like no luck was on our side, we gathered and sat down to watch a horror movie. Kara and Michelle claimed they didn't want to, but once it started they were clinging to our arms.
At the most inconvenient spot possible, the moment right before a jump scare was supposed to hit, we heard a noise coming from down the hall, a little girl's voice?
We got up and followed the sound of the voice. There, at the end of the hall, we found a doll. It was the same doll from the book.
"I want to play a game," it said in a disturbingly cheery voice.
"What game?" I asked, terrified completely of the situation.
"Hide and Seek," she said in a deep and demonic voice. Then, the lights went out. "Ready or not, here I come!"
