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

that some kind of solider was about to kill me,
i had this one when i was little kid.

I was being chased

Being chased da a psychotic killer and balls of fuoco shooting from the sky. I have some pretty weird dreams.

One time I had a nightmare where I was 25 years old and still going to a certain fandom based website that makes Chernobyl look like Times Square on NYE just to give out my most intellectual, well thought out risposte to various domande such as this one

Seeing a nuclear warhead drop in a field in front of me while I was standing in my backyard.
