Back when I was younger (I was around 14 years old) I was living in my old house in Shafter, CA. It's a small town, with some haunted places (the Green Hotel, for one). Now, I was never a doubter in the supernatural, but I was never a believer. My room was separated from the living room by a tiny... Hallway isn't the right word. It was like a little intersection that fanned to the bathroom, living room, my room, and my parent's room. I used to share a bunk with my younger brother (he was 10 at the time).
Before this, I never had any kind of supernatural or otherworldly experience. I was sleeping soundly, when all of a sudden I woke up. It was Tuesday night, my dad was away at work for the week, and I could hear my mother and brother snoring. They are both overweight, so I was surprised when I turned around (my back was facing the "hallway" and saw a lady in a gray dress. She was skinny, wearing a gray dress. The light in the living room (I assume it was that, or she was radiating herself) was on, and I could faintly through the dress, much like her silhouette in the dress fabric. She just stood there, and her face, while dark, had a sharp, angular beauty to it. I hid under the sheets, and went back to sleep. The next night, I again woke up at the same time (which was 12:37, I know because this happened for many nights) and saw her again. I told no one, and eventually I just stopped seeing her. Every night was the same though - I awake with my back towards the "hallway" and turn around to see her for a few minutes before I go back to sleep.
Anyone know what it might have been?
