Day dreaming. It's therapeutic and completely necessary for artists of all kinds. Yet we live in a culture that flings all kinds of accusations about laziness, worthlessness, and 'wasted' time. Add modern technology into the mix and most people over twelve have precious little time for the 'silliness' of day dreaming.
In an attempt to reclaim some brain space, time, and day dreaming, I'm working my way through a book called Bored and Brilliant by Manoush Zomorodi. It's a treatise on how our devices have stolen away the free time our brains once filled with day dreams and with synthesizing our experiences.
It's also a useful walk through the brain science that explains why we need wandering minds and 'useless' day dreaming.
So yes. Day dreaming - the fun, the terrible, the startling. Bring it all on. It's necessary. It's enlivening. Certainly, creativity and stories are built on the foundation of day dreaming.
The interesting piece is that with migraine, you get hallucinations. Not every time. But it seems to be a feature. Hallucinations are the feral cousins of day dreaming. Day dreams can be directed. Hallucinations can't. Yet they're useful, too. Some of the grimmest of my scenes came straight out of migraine hallucination. To be clear, tho, I'd flat give them up if I could exorcise the migraines. There are other ways to get into the altered states required to bring up vision, if not hallucination. I'd take it if I could get it. Until then, day dreams are welcome companions. Hallucinations, well. They show up, welcome or not, and stay until they're good and ready to leave.
