February 9.  Had a (mild) migraine tonight.  I get the funky lights/aura before I get a headache.  It’s like when you look at a light and then look away and you can still see the light.  There’s a blob that gets bigger and bigger, blocking my vision on one eye, with wiggly rainbow lights around the edges.  Here’s my drawing of it.  Luckily I was home, and I don’t get them too often.
