My Memory (Slender Man)

(??/??/2016)
(I'm sorry if my English still bad)
~~~~~~~~~~~~\\\~~~~~~~~~~~
I remember I'm at my school. My class has a camp to the woods. My Parents won't let me to go. But my sister  (16) defend me. My parents worried about me. But my sister said 'She Will be Fine.'
I'm Happy but Scared At the same time. I don't know why I'm Scared but i really have bad feeling.

And next day, I'm at school waiting all students. We prepared and talking about other things.
After that, we get into the bus.
I'm sitting with my best friend.
I'm daydreaming while my other friends talking and playing.

When we arrived at woods, I'm starting to throw up. And nosebleeds. My Teacher starting to worried me.
But I'm said 'I'm Fine.'
We started walking around. I feel watched. And my nosebleeds won't stop.
I saw something moving in the bush.
I started thinking 'Maybe it's just my imagination..'

And I began to walk again but I lost my friends.
I'm scared in that time
I feel someone behind me.
I turned my head..
I'm farsighted so I can't see shit.
That 'Thing' begin walking toward me.
He has no face.
Black suit and tie..
Tall..
Long arms..

And i fainted..😅

I can't remember the next tho..
