I am watching you

Where?

I woke up. As I opened my eyes, I was at my room. At my bed. But, but... Who was that...monster?
I looked at the clock. It said 12:00 pm. Wow, I slept a lot for sure. As I stood up... I felt like I was being watched. And every time I would turn around, I would see a shadow of the corner of my eye...
