Zach/David in “The Dream Sequence Always Rings Twice”

(in voiceover) I walked the streets for hours that night, my mind was reeling. I felt alone, adrift, I had never murdered anyone before. I had so many questions. How long was I supposed to walk the streets? How much guilt was I supposed to be feeling? How long will those signs float over my head?... (walks into a bar, still in voiceover) I wasn't ready to stop talking to myself yet, so I figured I might be better company if I had a couple of drinks.
