Vanessa,
Like you, I see metaphors everywhere. That's what those literature courses do to our brains. I also suppose that it has to do with these fast-changing times. Suddenly everyone is seeing metaphors everywhere. I kind of followed Fantasy and Science Fiction last summer. I joined in the middle of the course, so I didn't participate or write essays, but I read all the books and watched most of the videos. I couldn't join the winter course, but if they offer it again next summer, I would like to participate. I like it.
