Thanks Kimmy, I feel less kooky now!
I was browsing through the 'Mayo Clinic' and found an 'Exploding Head Syndrome' that seemed a little more plausable. Then I googled that name and was reading on Wikipedia and found this
http://en.wikipedia.org/wiki/Exploding_head_syndrome. Prettying interesting but one disclaimer made me laugh. . .
"Note that exploding head syndrome is not an example of spontaneous human combustion, nor does it otherwise involve the head actually exploding."
