I need help with my creative writing. What mark and grade would i get for this?

It is quite confusing to follow to be honest. But here are some simple edits to improve the SPAG part of your mark:Check your spellings - showering, haunted, bloodthirsty, throughCareful with punctuation - you have some random capital letters midway through sentencesDon't repeat words - splattered is used twice.Make sure it makes sense.

I really need help and tell me what I need to do to improve.

I jumped up all of a sudden, I saw it again! A dim mysterious and slender like figure. I clench my eyes and open them again to the cracked white ceiling which greets me every day. The canvas of the morning sky splattered with featureless colours. I try to let it slip of what corrupt creature I saw. My eyes were tired as an old man. I sprinted downstairs to help myself with food, however This place felt like a deserted island. My parents had left me for a week, but I didn’t know why? I was in a hotel! Where is everyone?
Forget it, I just could only think of eating there was rats in my stomach, I could eat a tonne of food! I rushed on devouring my inviting food. An idea jumped in my mind! I was thinking to go outside but I catch on I couldn’t go outside; I have a mountain of homework to do! Before I go back home.
Swiftly I saw it again the hair-raising, horrifying, and hideous mutant. My heart froze in seconds, It, gave a fearless star It had long crusty violent nails, I dashed upstairs as making a loud “thump” sound. My heart weighed a tonne I ran like a snail, I saw the dark figure It beamed closer and closer to me. I quickly leaped in my bed and showered the blanket over me and hid myself in here like a turtle. My brain was flooded with questions and fear, but after 100 years I finally pushed trough it and slowly got up. I was so gentle and quite as my life depended on it. This place is Huanted!
The breeze in the room went from gentle to a sharp, solid, and stiff atmosphere as I got closer to the door. My gut feeling told me not go near the door, I stopped in a heart beat and all I could think of is getting out of this mass situation. As the Rain smashed like a loud drum against the windows I leaped back closer to the window. I stared outside I saw, the storm was an untrained animal in a cage. Crashing. Roaring. Trying to destroy everything on its path. The door opened it make a “crunch” sound, I had no thought in my mind. I looked back. I saw that being again.
I felt nothing.

With no single thought! I jumped. I thought my life was flashing before my eyes. The sky was showring daggers. I finally got to the ground and I decided to sprint it down the road for safety as I was running, I looked back and The blunt creature gave me a hideous bloodthirst glare. "You are the chosen one" roared the frightening projection. I did nothing but worry and worry about what he meant but as my mind was running with paired thoughts, I ran myself to a haunted shed. The shed smelt like rotting apples and dead rats. I helplessly searched for the light switch, I was finally able to find the treasure and I turned the light on. I froze once again? Without not knowing why I did. Then I realized it took hold of me. I felt his long tentacle nails forcing me not to move. It gave me deadly look as I was its prey. I decided to jump so I can escape its ruthless hands.

Then finally I jumped. And my eyes closed without my permission

I jumped up all of a sudden. Then at last when I opened them, I was in my bed? The sky was splattered with unimaginative colours. The breeze was a warm blanket. The singing birds greeted me. I was back home! Where was I?

I thought to myself was it a dream?
