I like taking advantage of preconceived notions that everyone has and takes for granted, and flipping them inside out. I like taking something that everyone else accepts as a given, implying that it is how it usually is, and then flipping it on its head in dramatic fashion.
I also like just implying things in general that aren't necessarily true, and watching what theories people end up with.
I also seem to be totally incapable of writing things grounded in reality. There must always be something incredibly fantastic or unrealistic in my stories...
