I Slit His Throat With a Bread Knife

So that was disturbing.

Just had a flashback of last night's dream. I remember sleeping fitfully, as I've been sick. But the most striking part of the dream was about killing a man. Who it was, I don't remember. I don't think he was anyone, and yet he could have been anyone.

First, it was a nick. Then I slice a C-shape into his abdomen. It was totally effortless. Finally, I reach over and slit his throat. With a serrated bread knife. I watched as I made contact, but close my eyes when I hit the adam's apple - I couldn't watch that much.

What had he done?
