Seeing Things...Migraine, Aura, Hallucinations...
A break from Gilgamesh to talk about migraines, as in I saw something similar to this for half an hour this afternoon. They usually start as little tiny things in the center of my vision and then they grow and grow until they expand beyond the edge of my vision and then they are gone.
The reason I have three tries on here is that what I really need is something that moves and shimmers like a psychedelic special effect and I'm just not that good at creating special effects. If there is a filter that can turn a portion of an image into some kind of optical line effect like the pattern behind the old Green Hornet logo or something off Star Trek then I would probably have the right pattern, because the thing shimmers and shifts and seems to move, sort of like the electric marquee lights on Broadway, but in zig-zags and an arc.
These are known as "fortification auras" and a former Behavioral Science colleague of mine used to seem to delight in telling me that I had hallucinations. I seem to see them more often in the southern U.S. than in the west and they may be triggered by weather and humidity. I have 5 daughters and three of them see some type of aura, but everyone's is different, from a white snow effect to colorful spots to nauseating washes of icky cream and vegetable colors.
Below is a sequence description I made in 2003.
