I got another! This happened like, a long time ago, I mean 8, 9-ish. But the memory is still livid in my head.
I used to live in a very cheap home, small one bedroom with Mommy and Daddy, people even died there. But I was happy, I got a little room all to myself, plenty of toys, I was pretty much oblivious to it all. 
I had a closet to the wall on the right side of my bed, it came with the house, and it just was filled with bags and toys. Also a dead body that was cleaned out years ago. However, I slept easy for a few nights, but then came that dreaded night.
It was late, I was tucked in and unable to sleep. A soft blue shone outside my door, my parents couldn't get their hands on a night-light so they just left the TV on for me, and so deep shadows were casted all over my room. Long, dark, tendrils slithered across my walls, but I was used to it. As my eyes fluttered close for what I hoped was the last time, the closet creaked. 
The wooden door swung open, and a shadow [i]walked[/i]. Not just encased in black, but a literal shadow of a human. Flat, and jerky moving, it slid across the dirty-walls, out of my room, and the door banged shut. I was so terrified I couldn't even move, only after sunlight came did I dare jump out of my covers crying and running to Mommy. She was confused, I didn't dare tell her what I saw.
I since moved out of that house, but I can't shake off the memories.
