Had this video suggested to me by http://pebblinator.tumblr.com/ and it is really cool if you’re like me and have no previous understanding of 4D! 

Because dimensions are based on a range of frequencies, eventually this will be true. When the Earth’s frequency increases to the level where it will not support a 3D or 4D reality, everyone living on the planet will have to maintain a fifth dimensional vibration. 4D arrived in 2012, and will most likely be perceivable to everyone by mid-2014. –Sandra Walker
