I was going to read the article, but when I clicked on it, the page said it was no longer there. Anyway...
When I was probably 10 years old, I was staying overnight at a family friend's house. I woke up in the middle of the night to see two of the sisters that lived there just standing over the bed smoking cigarettes. I couldn't see their faces, but I could see the silhouettes and the ends of their smokes lit up. They were just standing there, side by side, not talking, looking at us as we slept. The next morning when I asked them about it, they said they hadn't been in that room at all the night before. Creepy.
Once, during the day, I was just sitting in my room writing or something. I had a candle lit. All of a sudden, while I was on the other side of the room, the candle just blew up into little pieces. Scared the shit out of me!
When I was maybe 12, my mom and I were the only two home and I was going to bed. When I went to my room and was just about to get ready to hop into bed, there was a loud pounding on my closet doors from the inside. They were closed. I was scared shitless, but I opened them to see if something might have fallen off the shelf. Nope. Everything was in its place. I went down our 2 flights of stairs to tell my mom and ask her to come check it out, but she dismissed it and told me to stop lying and go to bed.
There were a few other instances and of course scary movies make it difficult for me to go to bed sometimes (though I LOVE scary movies!). I'm not so sure if I believe in ghosts. Maybe a little... What's scary is not knowing what's out there.
