Crop Circles/Glyphs

This phenomenon did not start now, it started centuries ago and has gotten more complex.

You can detect the proximity of the circles/glyphs by the ionization of the air near you, i.e.:changes of the temperature and/or a characteristic sound produced by the accerlation of particles, when they are semi-stable in our reality.

How? The result of natural electro-magnetic force field created by water and undeground quartz deposits. The build up of an electrical magnetic charge from the quartz produces periodic energy discharge. These energy 'bolts' give the right conditions for these other dimensional civilizations to be able to communicate with us.

It has to do with perspective and perception.
