I was about 13 or 14, and yes odd stuff always happens to me. No one in my family believe in ghosts at all. I went to stay in my cousin's house for two nights, her birthday party was the day after the first night there. Her house was very old, cold, and it was built in the late 19th century. However, I wasn't expecting anything weird to happen, because she has loads of sisters and brothers who were everywhere in the house, but this happened in the early hours of the morning.
When you went up stairs, there is still a window where the other conservatory is built on, but this window has no glass so you can look into it or climb in to the other room, but you don't use it as a door. Well, the room I had to stay in was facing this window.
I fell asleep, and the covers where falling off me when I woke up at around 4:00 in the morning. I couldn't go back to sleep, so I just laid in the bed looking around the room, and outside on the landing. It was pitch black and the only sign of light was from the back yard lantern shining through the glass opposite the window facing me. I didn't even notice her, but she was there all the time as I was awake for about 45 minutes. I knew she was there because I could see her but it never clicked with me. When I came around, I glanced, and then it clicked. Who's that? I thought to myself, standing there, looking at me, was a tiny child looking around 5 or 6. She looked terrified, and she was frozen, pale and her mouth was open and she looked like she was going to break down crying or even scream. As usual, I crawled over the bed to the door and slammed it shut, put the light on, and got my mobile to try and see if my friends where awake, it makes me feel better.
