Given that it happens in a dream, would it be a Vaporeyawn? Anyway, the prompt for this day was Noise. My first idea was to have the protagonist hear a mysterious noise and, while trying to find the source, transforming into something related to it. It just didn't click with me though, so I ultimately decided to go with this. Also, this marks the point where I've started avoiding giving the protagonists names, because I'm worried that after I while I might start unintentionally repeating names, then people will wonder whether X person is the same as Y person with the same name, and bleh.

Doing the traditional comparison with what CrizBN did, our ideas were pretty far apart. Both noises were initiated by the protagonists, but at very different volume levels and for very different purposes. And also, being more sensitive to loud noises than most, his piece kinda makes me give a sympathetic wince.
