Dear Dead Dad

This is something I wrote in response to a prompt in school. It was "a hand in the dark holding a knife" and I had to continue it. I don't know how good this is or if i should continue...?

There was a hand in the darkness, and it held a knife. I spun around, grabbed the hand, and kicked. I hit where I thought the persons back should be. The man fell into the shallow light coming through the window. He dropped the knife. I took action quickly and grabbed it. I never thought those self-defense classes would pay off. Backing away slowly I demanded "Who are you? What are you doing in my house?"

"Trust me," the man said, "you don't want to know." I vaguely recognized the voice. But I couldn't be hearing what I thought I was. As I approached the light switch my attacker stood. He turned to face me just as the lights flickered to life. I saw somebody I never thought I would see again.

Standing in front of me was my dead father.

Should I continue with this?
