I'm not quite sure about "mindbreak", but I've had plenty of very scary dreams. I can't remember them much at all, but I know for sure there are plenty of violent ones and some semi-sexual-related ones. I say semi-sexual because I don't ever recall having an erotic dream -- mine are more so along the lines of suddenly realizing (in the midst of a completely unrelated plot) I'm only wearing a blanket or towel with nothing underneath at school, and proceed to semi-panicking about what should I do. Yeah, usually my dreams don't make sense. One moment there are robots chasing me and the next moment I'm trying to make a fried egg (I don't even know why) but failing even though I know how to make them just fine irl and the next moment I don't have pants. Good for all of you(?) who have sensible dreams with actual plot.
