And then, thinking back, I noticed other things - such as the fact that you rarely have conversations with other people in dreams, and that most people, if they can find a dream-book to open, find nothing useful or intelligible inside.
And then I thought, these kinds of limitations are quite understandable - after all, your brain is literally inventing an entire fantasy environment around you in real time. Looking at it like that, it's staggering how realistic dreams are, in spite of their shortcomings. On the Crescent sites, a lot of us are creatives of some kind - including writers - so we know how hard is is to produce something halfway realistic in real life. In fact, it suddenly struck me to ask, 'Looking at the sheer amount of creativity that goes into a dream, and knowing how much mental effort it takes to do anything similar when up and about, how come dreaming isn't more mental effort than being awake??'
