The girl in the roller skates(ano funny name )

My very first paranormal experience happened when I was maybe about 7 or 8 years old. At this time we lived in an older trailer, it was remodeled but still old, on a farm. I shared a room with my little sister at the time so we had 2 beds in the room. I had my bed on the opposite side of the room as her right under our window, right by the door. If I was laying on my back in bed I could look right down the hallway.Anyway, one night I for some reason couldn't sleep. I knew it was really late so I kept trying to sleep but something was keeping me up. I don't remember what exactly. Eventually I fell asleep. But it was a restless sleep. I had a dream about a girl in bellbottom (I don't know how to spell that) jeans with long straight blonde hair. She was running through our back yard, she looked scared, she ran to the barn. She hid in the far right corner of the barn then I saw a man standing in the door way. I mean, I assume he was a man it was just a dark shadow with a big build. Then I woke up.When I looked down the hallway to where my mother's room was I saw the same girl standing right in front of the door with her hand on the door knob as if she was about to enter the room. She was wearing the same bellbottom jeans but this time she had roller skates on. I put the covers over my head and hid that way for the rest of the night. I guess, considering I was only 7ish it could've just been my imagination or maybe my mind playing tricks from something I saw on tv. I'm not really sure. It's just always stuck in my mind.
