It occurred to me while noodling around with some writing practice today that I'm really not that good at writing very tense scenes. In fact I'd like to be better at writing frightening scenes - so, I put it to you esteemed worthies of the Workshop: how do you go about it? Have you seen it done particularly well somewhere (In fanfic or published fiction?)? And so on.
As for myself, I'm not really much of a horror aficionado, so there's a real gap in my knowledge where this is concerned
