So the scariest moment of my life takes place about 5 years ago when I was 9. Keep in mind that no one was inside the house at all.
  So one day my mother told me to go inside and put my clothes away. Being the respectful kid I am I did what she said. I grabbed the freshly folded basket of clothes and brought it inside to my room.
On my way to my room I pass my sisters room. (She wasn't home at the time.) I look over into her darkened room with only the slightest bit of light peeking through her very small window with the curtains closed. As I peered through the doorway I saw this black human shaped shadow sitting on her bed just looking at me. At first I wasn't really scared of seeing this black figure sitting at the edge of her bed I just thought it was a figment of my imagination. Turns out I was wrong.
I dropped the basket into my room as quickly as I could and ran back outwit to my mom. I told her about it and she replied with,
"I saw the same thing a few days ago walking in the living room."
  From that day on I have always  believed in ghosts. When ever I'm home alone and hear something I get so scared. I see dark shadows all the time. Even as I'm writing this. It's freaky.
