Paranormal psychology?
Hm... I don't write that category, so I'm not sure. I think as long as you have a paranormal concept, flesh it out really well. Psychology I would think you'd need to have a lot of internal dialogue or a more thoughtful speculative feel to it. What's the concept you have in mind?
Honestly, I just write to write. I try not to get caught up in what the 'rules' or guidelines are. I mean, it's good to know those things, but innovation and creativity don't stay within those bounds.
