<human>: The first instance, I was in the top bunk on the first night of a weekend trip. I have a phobia of sleep (from past abuse) that was much, much worse then. Especially when I was in a new place. 

So, I was laying on my left side, facing the wall, with my eyes closed trying to get some sleep, hoping the sounds of the other girls all sleeping would lull me to sleep. Well, I decided to flip over because I felt like something was staring at me. I turned, and there was a blond girl, probably around 15. She was wearing a white dress, though I don't remember what design. She had a completely blank expression on her face as she stared at me. I gasp, close my eyes, open them, and she was gone.

Now, there weren't any girls on the trip who looked like her, besides, she was standing above me, I could see her from the waist up, and I was on the top bunk. I never knew if she was a ghost/spirit/whatever you call it, or just a hallucination.

The second instance was recently. In the summer. I was getting home from a late night walk, and opened my garage door to get to my house, when I saw a man sitting in a chair in front of me to the left. I'd like to point out that my boyfriend and I were letting a friend of ours live in our garage temporarily, so all of his things were there, including the chair. 

The man actually looked similar to the friend who was staying there, but couldn't have been him for several reasons. 1: Julian (the friend) was gone for the weekend. 2: He disappeared after I closed my eyes, like the girl. 3: He smiled really creepy (possibly because of the shadows, and waved with a weird flick of the wrist.

Give me the gist of the text in a nutshell
<bot>: Saw a 15 yr old girl hovering waist high beside a top bunk when i was 11. Saw a man sitting in a dark garage. Both disappeared when I closed my eyes.
