The Old Lady in the Stairs

Had I not seen it with my eyes, or heard about it through people I trust, I truly don't know if I would believe it. Nevertheless, I had always been 50/50 on whether or not I believed in ghosts, until this date.

I was 13 years old at the time, approximately some 7 years ago to date. And still, after all this time I can vividly see the ghost that lived in our home. My mother was busy getting my little sister's costume ready in the bathroom, and I stood alone in our living room. It all happened so quickly and unexpectedly. I was standing on the living room floor, just inside the entrance leading to the kitchen. I glanced left, where the couch sat, and couldn't believe what I saw. It was a half witch, half demon looking figure. Its body was a greyish color, with loose wrinkly skin. It had the facial structures of a witch, the long nose, some warts, and the eyes were nothing but empty holes. Long thin hair sat upon both of her shoulders. The most memorable thing though, was the green shimmering light that came from the being. Upon seeing its presence, I let out a scream, and then it vanished. My mother asked what was the matter, but now I was a bit confused with the monster no longer sitting upon the couch. Had I simply been seeing things? I finally replied to my mom, telling her nothing had happened, and figured I was just imagining things. It actually completely slipped my mind until a few weeks later.
