If you want to write a good Creepypasta, you need to feel the story from the heart. I know, it sounds cheesy, but my friends and I all write Creepypasta stories, and it's because we feel strongly about what we're writing about. My character Feral is a Creepypasta, and I hold her dear to my heart. If you want to write a good pasta, here's my advice: You have to care about it! A Creepypasta you don't care about isn't one people are going to enjoy cause they can tell in your reading. Saying something like "she was scared" isn't telling the reader you WANT to write this. Saying "her eyes where wide with fear, and her body turned still like a statue with terror" that's what people want to read. :) I hope this helped!
