I've noticed for a couple of months, that if I've had a very vivid dream-like the most recent one of me being a member of the RCMP as a passenger on a bus full of dizzy people, I will more ofthen then not, wake up with a migraine. Not only do I have the pain, but there are the usual associated symptoms-like the noise, light and motion sensitivities. So I'm sure I'm not having a tension headache or tmj trouble from grinding my teeth. I don't see any flashes or spots, or sparkles in the dreams- some of my usual aura. I wonder if there's any correlation between vivid dreams/nightmares and migraine?
