What do you think of my chilling story?

I was home alone watching tv downstairs when I heard noises upstairs like someone banging at a door. I turned the tv off and walked up stairs cautiously. The lights were off so I turned it on. I walked down to the corridor where the bedrooms were presuming that's where the noise was coming from but there no one in any of the rooms. Suddenly the light went out. I was afraid and chills ran down my spine as if someone was watching me in the dark. I tried turning the lights back on, unfortunately they didn't work. I could her breathing in my parents room.I walked nervously toward the bedroom not knowing who would be in there. When suddenly I felt someone grab me on the shoulder. I was startled and instantly turned around in fear ?
