Sweet Dreams are made of these

I have strange dreams. The inside of my head is a very odd place. For instance, I'm the only person I know who occasionally dreams in text. The dream is going along "normally" or whatever the equivalent is for dreams, until I find myself reading the dream in a book. I don't always notice, because I'm picturing what I'm reading as I go along. So how do I realize that I'm reading and picturing my dream, rather than dreaming directly? I run across a misspelling.

Last night, I dreamed that I woke up and my computer was broadcasting a boxing match. It actually took me a while to figure out it was a dream when I later woke up for real. I was in my bed. My fan was running (I use it to cover up the noise from my building's parking lot). The only thing that later clued me in that it was a dream was that I was able to turn the computer off while crouched at the end of my bed. In real life, it's about 6 inches too far to reach from there.

For the funkiest dream I've had recently, it would be the dream that highlights my work as a librarian. I was cataloged. They tattooed my call number around my right ankle. Interestingly enough, I was cataloged under KF (US law, including legal research texts) and not Z (librarianship in general).
