Last night, I dreamt I was dreaming about having accepted a commission to write a book about dreaming.
I then dreamt that I woke up, realized I'd been dreaming, and told about my dream to an editor (no one I know in real life), who looked skeptical when I suggested that perhaps, after all, I should write a book about dreaming.
Then I woke up and realized I'd been dreaming about dreaming about having to write a book about dreaming, and then dreaming about telling someone about this dream I'd had.
So now I'm telling you.
I feel it's my duty.
