Frenemies

Let me start off saying that I know I haven't written in a while, and I'm sorry. Well, it's not like anyone actually reads this anyway, so I guess I'm not apologizing to anyone in particular. Before I forget, I'd like to kick this entry off with a strange dream I'd had last night.
Last night, I was too afraid to sleep in my own room. I'd been paranoid that Slenderman was watching me (ha ha). I decided to sleep on the couch, and before long, I was out. That was when this weird, alternate reality happened. I can only remember bits and pieces, but it started with me at my house. It was cloudy and cold which matched the tense atmosphere and emptiness in the streets. I had a large comforter of a beige shade around my shoulders, adorned with maroon flowers. Even then, I could feel eyes staring into my back along with a cold breeze whipping against my cheeks. I was sitting on my dad's metal black box in the trunk of his pick-up truck. That's when it got even stranger.
Shelbey was there. Shelbey was an old friend of mine; we got into an argument and ended up splitting. She used to be my closest friend, and I told her absolutely everything. She was sitting over to my left, looking pretty despite the dreary weather. The dream skips at this point, and I begin to speak.
I smiled genuinely. "Hey, hell with this."
She looked at me in shock, like I'd done something horrible. Yet only her head turned to face me as she hunched over.
"Can't we just be friends; Forget about that old crap?"
She was still confused. "...just... forget?"
"Yeah," I grinned.
The dream then skipped again, though I feel as if we went inside my kitchen for a short period of time. We were back outside. This time, Shelbey was on the opposite side of the truck bed, sitting on the edge of about where the handle would be to release the drop door. I started to talk again.
"Shelbey... There's some weird things... about me." She waited. I continued. The air felt tight. "I went through a lot of... er..."
"You lost weight,"
"A lot of it." I glanced to my feet. "That's what anorexia does,"
There was an extended period of silence. Then I tried to get to another subject.
"Shelbey, someone's watching me. It's serious - Slenderman."
She laughed at me, but in the dream, I felt clenching terror. It was ripping at my stomach. I looked over my shoulder in fear, and that's when it ended.
