Why me?

I always had the feeling that I was being watched, for as long as I can remember actually. I was looking out the window of my living room one day and when I opened the curtains, someone was standing right in front of me, outside of my house, just watching me. As soon as I screamed, this person bolted off into the woods. Why was this person standing there, watching me? Is it a man or a woman? I couldn't tell because whoever it was was wearing a black ski mask and dark clothing. I always had the feeling that I had been watched but I thought it was all just in my head.
