Hey, a lot of spiritual people believe in a new age on 21st of December 2012. To name one really interesting site where they all believe this look up TheSpiritSceince Great Shift They believes that the world will shift into the Fifth dimension and we will go throw three days of Darkness and come out into some type of new "world" or new age with no memory maybe in the fourth / fifth dimension.
This has actually got me quite worried. Whats your thoughts on these groups of people and the theory?
