Walk in the Dark

Last night's walk and my keys clinking. I could smell the lemon crushed by a passing car on the street. Too dark to be out alone. "What if someone is following me?"
And then, later in the night, the dream: I was taking my finals at University. I hadn't studied. I was looking at the paper, and the paper was looking at me. I have been in this dream several times in my life. It follows me.
