Strange Brain

Recently I've had two examples of the strangeness of the brain (I'm going to assume they're general quirks of all brains, not just mine). First, my warning signs for an oncoming migraine have changed over the past few months. They are now quite fascinating, not to mention handy. Whereas before I would get drowsy and dizzy only an hour before the migraine struck (often to the point where I shouldn't safely drive myself home), now I get a tingling in my hand or whole arm the day before. Then a few hours before the migraine I see spots. Because I'm not mentally impaired yet at the time these flags wave, I can admire their usefulness and bizarreness. The second strangeness has kept me awake the last two nights. My brain has been firing interesting, creative ideas around for my current novel as well as other stories. The night before last, I lay in bed typing half a chapter on my tiny phone screen so I could stay warm but not wake up my husband. Last night I got an idea for possibly my next novel. I noticed myself get really interested and fired up about it. Two problems, though: it was the middle of the night, and I'm not really all that close to finishing the current one. All I could do was get my ideas down and then lie there trying to tell my brain to calm down. I'm going to bed now to see what strangeness, if any, my brain offers tonight - hopefully it's in the form of dreams while I'm sound asleep.
