Is it normal to have some... twisted thoughts?
Ever since I can remember I've had some thoughts, which haven't really seemed naturally (if you can put it that way).
Like sometimes when I walk on the street late at night and I see at girl, suddenly I find myself thinking: "I could rape that girl. Nobody is around to notice". Or when I see a knife, I start thinking about killing somebody. Doesn't have to be somebody I know, just the first person I can find.
It's not because I'm mad at somebody. I've always had thoughts like that. And I doubt I could ever hurt anybody like that.
Is it normal to have those thoughts? And if not, should I go to a psychologist? And if I should that, how should I tell my parents it? Please say I'm normal; I'm worried.
