When I was 7, I woke up in the middle of the night with an earache. I decided to tell my mom and step dad and walked out of my room. Someone was sitting on the chair in the living room (about 3 feet away from my bedroom door). The person looked strange (the face was just kind of distorted) but it was dark and I couldn't see well. "Mom?" I asked. The person shook their head, and I started getting scared. "Mike?". The person shook their head again. I decided the best course of option was to go back to bed so I wouldn't have to walk past this...person. I climbed in bed, and closed my eyes for a second, before opening them and seeing the person standing in my doorway, smiling madly and nodding furiously.
Edited: I screamed at the top of my lungs and closed my eyes. My step dad came running out of his room in his underwear with a baseball bat (that was a scary sight in itself). There was nothing there, but clothes my mom had folded and put on the chair where strewn about the living room. For the longest time I told myself it was my cat, sitting on the clothes.
