Well, in my mind the jury is still out on the dissociation question - I just need to know a lot more about it. No question when I get the "dreaded green spot " it's a migraine, grateful I don't have actual head pain, but the bad ones cause my to get nausea, shiver, and break out in a cold sweat. Just not sure when I have lesser visual distortions if it is a lesser degree silent migraine or somehow emotional/mental.
