My story goes back to when I was around 13 years old sometime in the month of September. It happened on a Saturday morning sometime between one & three a.m. I had been having bad dreams for the last few nights and I had woken up to get a drink of water. Across from my bed there was a window with the shades drawn and an electronic piano standing underneath it. Next to the piano on the left side stood a tall black figure with its back to me. It looked almost like my sister (my sister tended to sleepwalk back then so that's just who I assumed it was).
It had long flowing black hair and was dressed in a long black dress. Everything about it was just pure black. It almost blended in with the shadows casted by my nightlight (under my piano). It just stood there with its head bowed and shoulders slumped. I slid out of bed (again, just thinking it was my sister sleepwalking) and walked over to her, not to wake her but to help her back to bed. I put my hand gently on her shoulder and felt what was beneath my hand stiffen.
Slowly the head turned to face me and all I saw were deep red eyes staring back at me. I felt my body tighten up in fear but I couldn't remove my hand from this thing's shoulder. It just stared at me not with anger or hatred but what looked like dark curiosity. It slowly turned its whole body to face me and finally I could take my hand away. I backed away and it seemed to smile at me. Its whole silhouette seemed fuzzy like static around its edges. It began to break apart from the feet into what seemed like ash. It just kept smiling at me until it completely vanished.
Of course after this I freaked out and ran back to bed and dove inside the covers. I stayed awake another hour out of fear and wore my nerves so much I passed out hidden under the covers. I awoke the next morning and there was nothing but what seemed like vague dusty footprints where the ghost (or demon...I'm not sure what it was) had stood. I told my mother about this and she thinks I was dreaming. I'm 18 now and I still think about that all the time...
