I was 11 when this happened. One night, when I had gone to bed, I saw a dream. In a dream I woke up to hear a noise and looked to my open bedroom door, where I saw a dark figure staring at me with red eyes. Thinking that it was my mother, I had called out to her multiple times, each time getting louder and louder. By the third time I called out to her, her red eyes did not move and I was getting frantic, screaming out to my mom and hiding beneath my covers.
Come to find out my mother was in the living room fast asleep and had woken up from my calls, running into my room. When I looked at her, the black figure had gone and I have not seen it since. But I guess I had always been afraid after that of what might be watching me or threatening to harm me at any given moment. I know that was a demon it was too dark and felt too evil.
