If you wish to understand the vortex phenomenon, go to this site:
http://www.thesonsofthelawofone.com/
and click on the PDF'S on the left. Download all of the David Wilcock books
and read them. They are regular books, just free. It will take you awhile to get through the material, but you will understand that the vortex is higher dimensional (frequency) energy streaming into our 3-D world.
I've been to Burlington, Wisconsin where a 'haunted woods' has a vortex that allows people to photo all kinds of transdimensional phenomenon. Mary Sutherland gives the tour on Saturday nights, contact her at:
