After having an oft-recurring dream several years ago, I made a point to remember it and puzzle over it.
In the dream, I visit continents number 8 and 9. In the dream, I always visualize a globe and zoom in on one or the other; usually both, and spend some time there. As usual in dreams, all is hazy, including the names and exact locations. (I sort of feel they belong in the Indian Ocean or even the South Atlantic, but I assembled this illustration by another feeling: remoteness.) And today I'll call them Yelliria and Xillmiu.
In the dream, I am always sort of amazed, but then I recall that these are the "continents everybody always forgets." We all learned about them in elementary school, but no one has really thought about them since. As always, in dreams, this makes perfect sense.
One of them is quite wild and relatively unpopulated. The other has a larger colonized population of modern sorts, with a feel of '50s Australia or New Zealand, only wilder, and without any particular negative attributes. I visit and have entertaining dream adventures. It's all new and bizarre and exciting..
I keep a globe in my living room, and one day while pondering another matter, I recalled my dream. And that's when I realized I had known about continents 8 and 9 all along. It was an "aha!" moment.
