Weirdness abounds

Understand that I have not written anything even remotely fictional since about the fifth grade. Suddenly, last month, a story came into my head and I had to write it down. It's only two pages long, but it's fiction. Then another one, though that one is on hiatus, because the muse doesn't know how it's going to end. Then nothing for about a month. Then this morning, an idea came to me. I have the visual for it in my head, but I don't know how it happened - it's based on TV characters and there has to be some impetus for these two characters to do what I'm picturing.

I've never wanted to be a writer, so these strange ideas out of nowhere are kinda freaking me out.
