Story me and my friends are working on... (cant post the whole thing but) is it any good? When a Demon and a Serial Killer Meet

Introduction
Hi my name is Elizabeth and I am the only survivor of the Demon/Serial Kil ler attack. You might be wondering what I am talking about, or you might be like the rest and think I am crazy and that I kil led them all, but I didn’t, I can only tell the truth even though the truth got me put in an insa ne asylum. But I am gonna tell you the whole story so it all started about a month or two ago.

Chapter 1

Around 2 months ago me and my sister, Katara, were home alone. Our parents are on a 3 month vacation. I’m surprised they trusted us for 3 months. So Katara and I were reading books, watching Television. You know like what normal kids would do. My Parents arranged it so that every 2 days a lot of food would come so we don’t have to go to the market. So the food had just arrived and I saw a shadow out of the corner of my eye. I said “Katara, where are you?” She screamed “UP HERE!” Sorry did I not mention we live in a mansion. Anyway, I went to where Katara was. So Katara wasn't pranking me, but what was that shadow? I went to where the shadow was but of course nothing was there. Dang the shadow must have gone somewhere else. Wait this is kind of like those Mur der Mystery shows! Oh but those aren’t real. Anyway I go up and check on Katara but she isn't there. “KATARA!” I yell. There is no answer. I slowly walk downstairs yelling Katara’s name. I look in closets and bedroom’s everywhere. Finally I find Katara in the office with ropes on her hands. I said “Katara, why did you tie yourself up and why didn’t you answer me?” Katara said “Elizabeth there was someone who did it.” I said “Don’t be silly Katara no more jokes.” “It’s not a joke.” she protested! I untied her and we walked downstairs, Katara went to watch T. V in the living room so I decided to get some food and watch T. V in my room. After 3 hours I got bored and went downstairs. Katara was still watching T. V I said “You're a couch potato.” Katara said “Yeah, yeah so are you, you were just watching television in your room.” I rolled my eyes
“Katara, do you mind if I have a friend over for the night?” I asked, “No I don’t mind as long as I can have a friend over as well.” she said. “Ok I am having Sky over. Who are you wanting to stay the night?” I asked. “I want to invite Erin.” she said. Just to clarify Erin is a girl. “Ok I will call them.” I grabbed my phone. Katara and I are exactly a year apart from each other in age. She was born Dec.18 2002 and I was born Dec.18 2001. I am 18 and she is 17 so her friends and I get along and my friends and her get along.
They came around 6:00 pm. “Hey Elizabeth, maybe we should have a scary movie night? What are your thoughts?” “I mean it does seem fun, let’s do it.” We picked Halloween, the one with Jamie Lee Curtis in it. It is the newest one. We all sat down to watch the movie. I cooked some popcorn and we all had drinks too. But, for some reason in the middle of it, I saw the shadow again. I am still wondering why my sister was tied up? But, hey we have friends over so I think we are fine for now. Then, all of a sudden the power went out.

I said “Dang the power went out!” Sky said, “Why don’t we get some flashlights and do spooky stories?” We are in a spooky story, I thought. We got flashlights and again I saw the shadow. I yelled “LEAVE ME ALONE!” All my friends jumped. “Umm ... Elizabeth are you ok?” said Sky. Katara said “Nah, she’s never been ok.” “Katara sh ut up. I saw a shadow, I saw this shadow before I found you tied up earlier!” I shouted “What are you talking about? I was never tied up?” said Katara. I screamed “WHAT?!?! Yes you were, earlier don’t you remember?” Katara looked at me weird. I screamed at the Shadow “WHAT DO YOU WANT FROM ME, LEAVE ME ALONE!” Now, I feel I should admit, I thought it was in my imagination for a while but then I realized that it was too real to be in my imagination. I saw my friends tied up and I said “Are you guys ok?” I blinked and my friends were standing right in front of me and were looking at me with concern. Katara said “She’s usually weird but not this weird. Elizabeth, are you ok?” I sobbed and said “No someone is messing with me, it's the guy in the shadow.”
