I fantasize about horrific situations to subject fictional characters to. This I recently recognized as being due to my long-term work on decompartmentalizing new information. Essentially I find rules of the fictional realm, put them together in ways not intended by the original author, and get the small rush of self-congratulations for "taking an idea to its logical conclusion." This results in being "too realistic" for many fantasy settings. On the other hand, it is why rationalist fiction so pleases me - it reminds me of how I think!
