You told me to write something about JRR Tolkien in my journal, I started to forget even as I was writing it down.

It's strange how people show up in our dreams.
It takes months for a new baby sibling to become a regular; or suddenly a person you know about, an actor or writer or anybody will just be there one night, saying and doing things you don't quite remember on waking.
You might fall in love with a boy you actually thought was kind of ugly after a particular dream of him, and then you'll start watching him and notice how kind and sweet he is to his little sister, and you'll know something about him, something new and rare and precious. He'll become a part of you, or maybe he was already a part of you, but it took a dream for you to understand that.
