I recommend the book "The Skull speaks" for anyone interested in the crystal skulls.
It was originally released in 1985. A real copy fetches an high price, luckily it has now been re-released as an E-book.
Anyway, so far I've only read 28 pages but the content is really stunning.
It's 9 sessions with Carole Davis, a medium, who talks as the skulls voice.
The skull contain multiple minds
According to the (Mitchell-Hedges) skull, it's 17000 years old
It was made by energy beings from another galaxy.
Seems like they created the crystals and a lot of the other matter with their mind.
And, yes according to the skull, Atlantis will rise...
Anyway, 117 pages very interesting reading.
Crystalskulls.com sells it...
