Would a creative writing topic be acceptable to write about (Common App Essay)

Yes, I do understand that it must be written well, be personal, and match the prompt (of course) or else the essay is going to suck anyway. However, I would really like to know is whether this could be a valid topic to write about. In short, I would basically explain how/why I am passionate about creative/fiction writing an get into detail.

How would colleges typically view an essay like this? Do they just prefer personal experiences instead of things like passions or interests, even if those may also be personal? Because I’m gonna be honest, I can’t think of a single personal experience I can write about.
