I can still remember this, even though I was about nine years old when it happened. I was at my friend's house (we call her DJ. Still do) for a sleep over. I had to sleep on an air mattress because I was the only one who could stand it. My head was on the side nearest the door. I woke up later that night, only to find the outlines of three people. I knew they were ghosts because I had heard about that kind of thing. One looked like a woman, like she was holding a baby and watching some non-existent show on the turned off TV screen. The third was leaning over me, looking at me. I was so scared! Being only nine, I thought that hiding under the blanket would work, so I did, and eventually got back to sleep.
The next day, I was driving to McDonalds or something and I told my friend and her mom. Her mom said that she knew there were ghosts in the house. One time, while DJ's dad was at work and DJ was at school, one of DJ's stuffed animals was thrown across the hallway. Another time, her mom was downstairs playing pool and her grandparents said that they had heard her laughing upstairs... They got kind of ticked because they thought DJ's mom had tricked them. She also went on to tell other stories, but I can't remember them.
I've seen these ghosts and others several times since.
