Hi there! I don’t really know much about this area, but I like the theory that dreams are a useful way for our brains to process information. For example, I’ve got exams coming up and all I seem to dream about at the moment is sitting those damn things — which I guess is my brain’s way of mentally preparing me for all the different outcomes.
And we can reach syntheses through them too — the best thing I ever drew came to me in a dream. I dream fragments of music as well, although I never remember them.
