Girl, just do what আপনি do. If it ends up being a story about E.T. and a zombie falling in love, I don't think that we'd even care! I'll read in whichever way আপনি go with it, and I will support আপনি the whole time through.
আপনি should think about the story that আপনি want to write. If it's paranormal, then run with it. If not, then go with it. You're allowed to write আরো than one story, so try a little bit of everything.
