Last night, I dreamed I was a werewolf. According to the dream, werewolfness was an autosomal recessive inherited condition, because my dreams like to be specific about those sorts of things. Symptoms typically manifest in mid-teens to mid-20s and include pronounced excitement or anxiety at the prospect of the next full moon followed by turning into a wolf for the duration of any night in which a full moon is in the sky. Exact nature of the symptoms vary, with some werewolves retaining full mental faculties while transforming physically while others act like wolves for the duration of their transformation.
In the dream, I secluded myself in a construction site for my first transformation, and discovered that I transformed physically while remaining mentally human. Except the next morning, I discovered that I'd killed four people who were trespassing in the construction site. After reverting to human the following morning, I was captured and imprisoned by an organisation that hunts werewolves but sued for my freedom on the grounds that being a werewolf isn't actually a criminal offence.
I was actually surprised to discover my subconscious wrote what sounds like a passable story. I don't think I'm actually going to write it though.
