ANYONE ELSE EXPERIENCE AURA WITHOUT MIGRAINE?

I never would have looked this up if it weren't for that Serene Branson incident at the Grammies a few years ago. (If you have no idea what I'm talking about: https://m.youtube.com/watch?v=dwHpBwAxDIs )
  1. This is aura:
  2. It doesn't look exactly like that, but it's close
  3. It's a visual thing that sometimes accompanies migraines (or so I've read.)
  4. Except I don't think I've ever had a migraine. And I've experienced this my entire life
    Seems like it happens more often in winter/autumn. Also night driving, caffeine or lack thereof seem to be variables.
  5. So, yeah. Anyone else experience this?
    I don't really want to go to WebMD - I'd rather not go down that particular hypochondria rabbit-hole. Just curious if anyone else experiences this and what it's like for them.
