@Nobody7568 Yes. You know those weird dreams you get after a night of being really stressed? Or when you start to disassociate from reality and your train of thought ends up somewhere really weird?
Listen to that stuff. Some of my best story ideas came from letting my train of thought go off the tracks. Like "Lunars of the Caribbean". I believe the thought I first had that arrived at the then story idea was "Wow, what a**hole named that poor Pokemon Gloom? Why does he have to hate of a flower, damn." Then I thought of Orlando Bloom because gloom and bloom rhyme. Then I was thinking of his roles, specifically pirates of the Caribbean. Then I thought about "Captain" Jack Sparrow and how he had to remind everyone he was a captain, and "THORNE HAD TO DO THAT TOO!" popped into my head. "I SHOULD PUT THEM TOGETHER!!!" So yeah, listen to all your weird thoughts that don't really make sense. They can lead you to a story that does.
Also, if you start writing a story, you don't necessarily have to know the ending, or even the middle. Like "The Fire Didn't Stop Her." I honestly had no idea what was gonna happen past chapter 5 besides Kai and Cinder getting to be happy together - which I didn't really know how I was going to do that. I have started so many stories with no idea how to end them, because I know that if you stick with a story that it can write itself. Sometimes I feel like a reader with my own work because even I have no idea where the story is going. And to be honest, most of the things people point out and say, "Oh my gosh, you were planning that all along, weren't you!", are just things that popped into my head last second or I had no idea were in the story to begin with.
References to other fandoms are never horrible. If they're relevant and make you smile, go for it.
I listen to music while I write. For specific emotions I want in my writing, I'll listen to specific songs. Ex: Action scene, I listen to Phoenix by Fall Out Boy
