When I was about 16/17, I would randomly daydream about how I would kill a nondescript, hypothetical person based on specifics such as motive, victim specs (habits and skills), location, and so on, how I would cover it up, and what my alibi would be. I also would daydream about how I would booby trap a house/alleyway/woods/whatever, and mentally design the mechanisms needed to make the traps work. Sometimes in great detail, depending on how bored I was. I still do.

Don't get me wrong. I don't intend to ever carry out the idle imaginings. I don't even intend to have them, they come about when I get bored and my mind wanders. I'm not violent at all. A little piss-y at times, sure- but hey, I'm a teenager, female (damn hormones), and am on corticosteroids for weak kidneys (even more moodiness! yah! /sarcasm).

I am an 18yo female of above average intelligence (133 IQ), and am not stupid enough to actually tell anyone I know about this, and am too shy and proud to seek help, not that I could trust it.

Oh, and BTW: one of my spam prevention words is "spurple", which sounds really, really funny when spoken aloud.
