Wow, I had a dream the other night that I killed somebody too! This girl was threatening my family with a gun, and I went up to her and confronted her. She put the gun to my head. Then I saw a gun on the table next to me, so I quickly picked it up and put it to her head. I hesitated, hoping she'd lower her weapon, but I was afraid the longer I waited, the more likely it was that she would fire and I'd be dead, so I pulled the trigger and killed her. But I realised at that moment that just an instant before I pulled the trigger, she'd dropped her gun. I felt terrible, and I woke up.
