I'm probably a biological aberration in the sense that I could be dreaming (not daydreaming!) and at the same time aware of the surroundings of my sleeping body. I don't really know how that's possible. It was doubly weird a few days ago when I was quite tired and sleepy, and in my dream, I was still sleepy. I'm already sleeping... what more does my dream-self want, to sleep in my dreams too?
Of course just now, I awoke from a dream that revolves around a motif that recurs over the year. I don't get it often yet the theme is always the same. It's not exactly a nightmare but neither is it a pleasant experience. My bad dream? Learning Chinese, complete with answering exams you're bound to fail because you leave too many blanks.
