I had a dream that the ground I was standing on vanished before the Chile quake, and woke up suddenly!

Abstract In two surveys of headaches it was noted that their incidence had increased significantly within 48 h prior to earthquakes from an incidence of 17% to 58% in the first survey using correlated samples and from 20.4% to 44% in the second survey using independent samples. It is suggested that an increase in positive air ions from rock compression may trigger head pain via a decrease in brain levels of the neurotransmitter serotonin. The findings are presented as preliminary, with the hope of generating further research efforts in areas more prone to earthquakes.

I found this on headaches and earthquakes. Apparently, there's been a study on it. The paper can be found at International Journal of Biometeorology
