What's the worst dream you've ever had?

I had the most horrible dream, that is, the dream should be a particularly dark feeling, just like the street lamps in the city, all of them were broken. Then I felt like I was being chased. Then when I woke up suddenly, I was hiding in a dark alley, with street lights on and a trash can under the camera. Then I watched a black man dragging a very big garbage bag, and there was a garbage bag inside. There should be someone inside, and then I felt like there was a smell of blood around me, so I ran like crazy, ran like crazy, and then I woke up.
