This happened last year, i'm no to sure what month or day exactly. I was on my computer and my brother was next to me, he was playing the xbox. It got kinda cold and i sat next to my brother to tell him something. When i sat down on the couch i glanced over to my door and i saw a girl sitting in the corner. She was obviously a ghost because she was kinda white gray-ish and i saw through her, she was sitting with her legs up against her chest and her arms were wrapped around them. I couldn't really see her face, she staring down, she had long black hair that fell to the sides, i could kinda see her face, but it was black, there wasn't anything there, she was wearing a hospital dress. She didn't look up at me and she never said a word to me, i looked away and i looked back, she was gone. I do think she's here in the house because at some points my house gets really cold, but i know it's her because most of the time the air is off. Sometimes when my door is opened a little it kinda moves little by little, my mom says it's the air but the air never hits my room. I don't know why the girl is here, i don't here her talk, but sometimes i feel someone touching me, sometimes i wake up with a bruise or a weird scratch on my body. I think it's her trying to tell me something, what do you guys think?
